NASA Technical Reports Server (NTRS)

Earthquake engineering research capabilities of the National Aeronautics and Space Administration (NASA) facilities at George C. Marshall Space Flight Center (MSFC), Alabama, were evaluated. The results indicate that the NASA/MSFC facilities and supporting capabilities offer unique opportunities for conducting earthquake engineering research. Specific features that are particularly attractive for large scale static and dynamic testing of natural and man-made structures include the following: large physical dimensions of buildings and test bays; high loading capacity; wide range and large number of test equipment and instrumentation devices; multichannel data acquisition and processing systems; technical expertise for conducting large-scale static and dynamic testing; sophisticated techniques for systems dynamics analysis, simulation, and control; and capability for managing large-size and technologically complex programs. Potential uses of the facilities for near and long term test programs to supplement current earthquake research activities are suggested.

The Challenge of Centennial Earthquakes to Improve Modern Earthquake Engineering  

SciTech Connect

The recent commemoration of the centennial of the San Francisco and Valparaiso 1906 earthquakes has given the opportunity to reanalyze their damages from modern earthquake engineering perspective. These two earthquakes plus Messina Reggio Calabria 1908 had a strong impact in the birth and developing of earthquake engineering. The study of the seismic performance of some up today existing buildings, that survive centennial earthquakes, represent a challenge to better understand the limitations of our in use earthquake design methods. Only Valparaiso 1906 earthquake, of the three considered centennial earthquakes, has been repeated again as the Central Chile, 1985, Ms = 7.8 earthquake. In this paper a comparative study of the damage produced by 1906 and 1985 Valparaiso earthquakes is done in the neighborhood of Valparaiso harbor. In this study the only three centennial buildings of 3 stories that survived both earthquakes almost undamaged were identified. Since for 1985 earthquake accelerogram at El Almendral soil conditions as well as in rock were recoded, the vulnerability analysis of these building is done considering instrumental measurements of the demand. The study concludes that good performance of these buildings in the epicentral zone of large earthquakes can not be well explained by modern earthquake engineering methods. Therefore, it is recommended to use in the future of more suitable instrumental parameters, such as the destructiveness potential factor, to describe earthquake demand.

Proceedings of the third U. S. national conference on earthquake engineering. Volume II  

SciTech Connect

During the past quarter century the North American continent has experienced a number of damaging earthquakes, among which were the 1964 Alaska earthquake, the 1971 San Fernando, California, earthquake, and most recently the 1985 Mexico City earthquake. A large number of smaller earthquakes have occurred during this period, all of which, along with large earthquakes that have occurred in other parts of the world, serve to remind one that the earthquake hazard is real. In view of potential loss of life and the economic losses that could result from large earthquakes, it is important that the United States continue its vigorous efforts towards mitigating the hazards of earthquakes including developing and implementing safe and economic methods of earthquake-resistant design and construction. In the light of the foregoing observations it it fitting that this Third U.S. National Conference on Earthquake Engineering be held in 1986 at Charleston, South Carolina, on the one-hundred-year anniversary of the 1886 Charleston earthquake. Although intended primarily for participation by U.S. practitioners and researchers, participants from many other parts of the world are also present. From the more than 300 papers offered for publication and presentation, over 200 papers are published in the three volumes of Proceedings and the single volume of Post-Conference Proceedings.

An Online Platform for Resources and Collaborative Research on Earthquake Source  

NASA Astrophysics Data System (ADS)

We develop the online platform http://equake-rc.info for collaborative research on earthquake sources. The platform has three main features: (1) finite-fault earthquake source models (SRCMOD) database, (2) Source Inversion Validation (SIV) Benchmarks and its Wiki, and (3) software Codes for Earthquake Rupture and ground-motion Simulation (CERS). SRCMOD collects and disseminates source models of past earthquakes. SIV aims at benchmarking the current state-of-the-art in earthquake source inversions and developing robust approaches to quantify uncertainties in the source models. CERS currently has three software packages. These include 'RupGen' for generating synthetic earthquake rupture models, 'Stress2Slip' for computing on-fault static stress changes corresponding to a slip distribution, and 'BB-Simulation' for computing and integrating high frequency synthetics with low frequency waveforms to generate hybrid broadband seismograms. We envision that this online platform will be useful in advancing research on earthquake source processes and earthquake engineering.

Engineering Seismic Base Layer for Defining Design Earthquake Motion  

SciTech Connect

Engineer's common sense that incident wave is common in a widespread area at the engineering seismic base layer is shown not to be correct. An exhibiting example is first shown, which indicates that earthquake motion at the ground surface evaluated by the analysis considering the ground from a seismic bedrock to a ground surface simultaneously (continuous analysis) is different from the one by the analysis in which the ground is separated at the engineering seismic base layer and analyzed separately (separate analysis). The reason is investigated by several approaches. Investigation based on eigen value problem indicates that the first predominant period in the continuous analysis cannot be found in the separate analysis, and predominant period at higher order does not match in the upper and lower ground in the separate analysis. The earthquake response analysis indicates that reflected wave at the engineering seismic base layer is not zero, which indicates that conventional engineering seismic base layer does not work as expected by the term 'base'. All these results indicate that wave that goes down to the deep depths after reflecting in the surface layer and again reflects at the seismic bedrock cannot be neglected in evaluating the response at the ground surface. In other words, interaction between the surface layer and/or layers between seismic bedrock and engineering seismic base layer cannot be neglected in evaluating the earthquake motion at the ground surface.

Deep Downhole Seismic Testing for Earthquake Engineering Studies  

SciTech Connect

Downhole seismic testing is one field test that is commonly used to determine compression-wave (P) and shear-wave (S) velocity profiles in geotechnical earthquake engineering investigations. These profiles are required input in evaluations of the responses to earthquake shaking of geotechnical sites and structures at these sites. In the past, traditional downhole testing has generally involved profiling in the 30- to 150-m depth range. As the number of field seismic investigations at locations with critical facilities has increased, profiling depths have also increased. An improved downhole test that can be used for wave velocity profiling to depths of 300 to 600 m or more is presented.

One research from turkey on groundwater- level changes related earthquake  

NASA Astrophysics Data System (ADS)

Groundwater levels are recorded by limnigraphs in drilling wells in order to determine groundwater potential accurately and reliable under hydrogeological studies in Turkey State Haydraulic Works (DSI) set the limnigraphs to estimate mainly groundwater potential. Any well is drilled to determine and to obtain data on water level changes related earthquake up today. The main purpose of these studies are based on groundwater potential and to expose the hydrodynamic structure of an aquifer. In this study, abnormal oscillations, water rising and water drops were observed on graphs which is related with water level changes in groundwater. These observations showed that, some earthquakes has been effective on water level changes. There is a distance ranging to 2000 km between this epicentral and water wells. Water level changes occur in groundwater bearing layers that could be consisting of grained materials such as, alluvium or consolidated rocks such as, limestones. The biggest water level change is ranging to 1,48 m on diagrams and it is recorded as oscillation movement. Water level changes related earthquake are observed in different types of movements below in this research. 1-Rise-drop oscillation changes on same point. 2-Water level drop in certain periods or permanent periods after earthquakes. 3-Water level rise in certain periods or permanent periods after earthquakes. (For example, during Glck Earthquake with magnitude of 7.8 on August, 17, 1999 one artesian occured in DSI well ( 49160 numbered ) in Adapazari, Dernekkiri Village. Groundwater level changes might easily be changed because of atmosferic pressure that comes in first range, precipitation, irrigation or water pumping. Owing to relate groundwater level changes with earthquake on any time, such changes should be observed accurately, carefully and at right time. Thus, first of all, the real reason of this water level changes must be determined From 1970 to 2001 many earthquakes occured in Turkey ( Ktahya-Gediz Earthquake on March, 28, 1970, Diyarbakir-Lice Earthquake on September, 6, 1975, Van-Muradiye Earthquake on November, 24, 1976, Erzurum-Kars Earthquake on October, 30, 1983, Glck Earthquake on August, 17, 1999 , Afyon-Sultanhisar Earthquake on February, 3, 2002). Furthermore, Iran Earthquake on November, 27, 1979 has been measured and recorded from thousands kilometeres away in drilling wells in Turkey. Altough there are a lot of studies and researches on earthquake prediction and groundwater level changes related earthquake, it is still difficult to say certain results are obtained on this subject. Nowadays, it is well known the importance of these researches on earthquakes. Due to take certain results on earthqauke-water level changes relations, studies must be carried out on this way.

SCEC-VDO is written in Java/Java3D with an extensible, scalable architecture. An increasing number of SCEC-VDO datasets are obtained on the fly through web services and connections to remote databases; and user sessions may be saved in xml-encoded files. Currently users may display time-varying sequences of earthquake hypocenters and focal mechanisms, several 3-dimensional fault and rupture models, satellite imagery - optionally draped over digital elevation models - and cultural datasets including political boundaries. The ability to juxtapose and interactively explore these data and their temporal and spatial relationships has been particularly important to SCEC scientists who are evaluating fault and deformation models, or who must quickly evaluate the menace of evolving earthquake sequences. Additionally, SCEC-VDO users can annotate the display, plus script and render animated movies with adjustable compression levels. SCEC-VDO movies are excellent communication tools and have been featured in scientific presentations, classrooms, press conferences, and television reports.

Performance-based seismic design of nonstructural building components: The next frontier of earthquake engineering  

NASA Astrophysics Data System (ADS)

With the development and implementation of performance-based earthquake engineering, harmonization of performance levels between structural and nonstructural components becomes vital. Even if the structural components of a building achieve a continuous or immediate occupancy performance level after a seismic event, failure of architectural, mechanical or electrical components can lower the performance level of the entire building system. This reduction in performance caused by the vulnerability of nonstructural components has been observed during recent earthquakes worldwide. Moreover, nonstructural damage has limited the functionality of critical facilities, such as hospitals, following major seismic events. The investment in nonstructural components and building contents is far greater than that of structural components and framing. Therefore, it is not surprising that in many past earthquakes, losses from damage to nonstructural components have exceeded losses from structural damage. Furthermore, the failure of nonstructural components can become a safety hazard or can hamper the safe movement of occupants evacuating buildings, or of rescue workers entering buildings. In comparison to structural components and systems, there is relatively limited information on the seismic design of nonstructural components. Basic research work in this area has been sparse, and the available codes and guidelines are usually, for the most part, based on past experiences, engineering judgment and intuition, rather than on objective experimental and analytical results. Often, design engineers are forced to start almost from square one after each earthquake event: to observe what went wrong and to try to prevent repetitions. This is a consequence of the empirical nature of current seismic regulations and guidelines for nonstructural components. This review paper summarizes current knowledge on the seismic design and analysis of nonstructural building components, identifying major knowledge gaps that will need to be filled by future research. Furthermore, considering recent trends in earthquake engineering, the paper explores how performance-based seismic design might be conceived for nonstructural components, drawing on recent developments made in the field of seismic design and hinting at the specific considerations required for nonstructural components.

Research Spotlight: Spooky action at a distance, for earthquakes  

NASA Astrophysics Data System (ADS)

On 27 February 2010 a magnitude 8.8 earthquake rocked millions of Chileans from their slumber, but the South American people weren't the only ones so affected. New research by Peng et al. suggests that the trembling off the Chilean coast could have triggered a swarm of shallow earthquakes nearly 10,000 kilometers away in central California. The team identified four earthquakes with magnitudes of 2 or higher, with the largest of the group being a M 3.5 quake that rattled the Coso geothermal field. The affected region is plagued by small earthquakes, but when the authors calculated the chance of a swarm so neatly following the Chilean earthquake, they inferred that the two seismic events were probably connected. The authors also saw a cluster of deep, low-frequency earthquakes along the Parkfield-Cholame section of the San Andreas Fault that also appeared to be influenced by the Chilean event. The researchers suggest that the timing of the California earthquakes was affected by the arrival of Love waveshorizontal surface movement that would have traveled out from the epicenter of the Chilean earthquake, pushing already stressed faults over the edge.

K12 Education Program Lessons Learned at the Center for Earthquake Research and Information  

NASA Astrophysics Data System (ADS)

The Center for Earthquake Research and Information at the University of Memphis has been committed to increasing awareness for Seismic Hazard, Earthquake Engineering, and Earth Science among Mid-America's policy-makers, engineers, emergency managers, the general public, and K-12 teachers and students for nearly three decades. During that time we have learned many lessons related to providing effective education and outreach programs, especially for K-12 students. The lessons learned from these activities may be particularly appropriate for other regions where large earthquakes occur infrequently but have disproportionately high consequence areas due to low attenuation of seismic waves. Effective education programs in these settings must provide a consistent message across many states to a wide variety of socio-economic groups and professional communities through the leveraged resources of various groups and agencies. It is also beneficial to hire and train staff with K-12 teaching experience to work directly K-12 education organizations, and science curriculum coordinators.

Academic Research Engine  

NSDL National Science Digital Library

Last week, Student Advantage announced its new academic research engine, developed in partnership with Northern Light (see the September 19, 1997 Scout Report). Students can keyword search 25 different subjects either individually or simultaneously. Some features adopted from Northern Light's search engine make Student Advantage likely to reduce, at least, the ratio of student frustration to success when attempting to do Internet research. First, results of an initial search include a sidebar that organizes returns in subject folders allowing users to focus only on those that seem most promising. Second, the "drill and search" feature allows students to then refine their searches within these subject folders. This two-step process mitigates the centrifugal Internet experience most student-researchers encounter. The site also features a listing of online reference sources and a free download of Q-Notes, software for electronic note-taking (for PCs only). (Caveat: Many of the book-length texts listed in results are merely links to Amazon.com, and some of the articles listed are held in Northern Light's fee-based Special Collection.)

Multi-disciplinary Hazard Reduction from Earthquakes and Volcanoes in Indonesia - International Research Cooperation Program  

NASA Astrophysics Data System (ADS)

Indonesian and Japanese researchers started a three-year (2009-2011) multi-disciplinary cooperative research project as a part of "Science and Technology Research Partnership for Sustainable Development" supported by the Japanese government. The ultimate goal of this project is to reduce disaster from earthquakes, tsunamis and volcanoes by enhancing capability of forecasting hazards, reducing social vulnerability, and education and outreach activity of research outcomes. We plan to provide platform of collaboration among researchers in natural science, engineering and social sciences, as well as officials in national and local governments. Research activities are grouped into: (1) geological and geophysical surveys of past earthquakes, monitoring current crustal activity, and simulation of future ground motion or tsunamis, (2) short-term and long-term prediction of volcanic eruptions by monitoring Semeru, Guntur and other volcanoes, and development of their evaluation method, (3) studies to establish social infrastructure based on engineering technologies and hazard maps, (4) social, cultural and religious studies to reduce vulnerability of local communities, and (5) studies on education and outreach on disaster reduction and restoration of community. In addition, to coordinate these research activities and to utilize the research results, (6) application of the research and establishment of collaboration mechanism between researchers and the government officials is planned. In addition to mutual visits and collaborative field studies, it is planned to hold annual joint seminars (in Indonesia in 2009 and 2011, in Japan in 2010) that will be broadcasted through internet. Meetings with Joint Coordinating Committee, composed of representatives of relevant Indonesian ministries and institutions as well as project members, will be held annually to oversee the activities. The kick-off workshop was held in Bandung in April 2009 and the research plans from 22 different themes were explained and panel discussion was conducted. Then, the project officially started in June 2009. The first plenary workshop was held in October 11-14 in Aceh, Indonesia, at the occasion of Indian Ocean-wide tsunami evacuation drill of IOC (Inter-governmental Oceanographic Commission). Considering that disastrous earthquakes occurred on 2nd September 2009 (Mw7.0) in the south of Java and on 30th September 2009 (Mw7.5) nearby Padang, central Sumatra, special reports for these earthquakes were presented. In particular, the latter earthquake that devastated the city of Padang was of great interest because its epicenter is located in a seismic gap called "Mentawai gap" where a large interplate earthquake is expected to occur in the near future. Research teams from our project were urgently deployed to the area for investigating disasters due to the September 2009 earthquake and trying to find effective countermeasures to the coming larger event.

Ease of data access and data standards are two issues critical to the success of GIS technology when applied to earthquake hazards research problems that require geotechnical engineering and related data. Efforts to reduce data accession costs and to streamline the data exchange process will result in short-term cost and time saving and will add long-term value to the data sets themselves. Such efforts might include centralized data centers, standardized data base designs and formats, cooperative efforts to fill data gaps, and standardized distribution methods and media.

In this lesson, students explore the causes of earthquakes and their impact on the geology of an area and on human societies. They begin by looking at the role tectonic plates play in creating the forces that cause earthquakes, to help them understand why earthquakes occur when and where they do. Hands-on activities illustrate how rocks can withstand a certain amount of stress, but that every material has its breaking point. When rocks break underground, an earthquake occurs. In the last section, students explore the impact earthquakes have on humans and look at the efforts scientists are making to better understand and predict these sometimes deadly events.

Reflections from the interface between seismological research and earthquake risk reduction  

NASA Astrophysics Data System (ADS)

Scientific understanding of earthquakes and their attendant hazards is vital for the development of effective earthquake risk reduction strategies. Within the global disaster reduction policy framework (the Hyogo Framework for Action, overseen by the UN International Strategy for Disaster Reduction), the anticipated role of science and scientists is clear, with respect to risk assessment, loss estimation, space-based observation, early warning and forecasting. The importance of information sharing and cooperation, cross-disciplinary networks and developing technical and institutional capacity for effective disaster management is also highlighted. In practice, the degree to which seismological information is successfully delivered to and applied by individuals, groups or organisations working to manage or reduce the risk from earthquakes is variable. The challenge for scientists is to provide fit-for-purpose information that can be integrated simply into decision-making and risk reduction activities at all levels of governance and at different geographic scales, often by a non-technical audience (i.e. people without any seismological/earthquake engineering training). The interface between seismological research and earthquake risk reduction (defined here in terms of both the relationship between the science and its application, and the scientist and other risk stakeholders) is complex. This complexity is a function of a range issues that arise relating to communication, multidisciplinary working, politics, organisational practices, inter-organisational collaboration, working practices, sectoral cultures, individual and organisational values, worldviews and expectations. These factors can present significant obstacles to scientific information being incorporated into the decision-making process. The purpose of this paper is to present some personal reflections on the nature of the interface between the worlds of seismological research and risk reduction, and the implications for scientists and information delivery.

Why is earthquake prediction research not progressing faster?  

NASA Astrophysics Data System (ADS)

As a physical phenomenon, earthquakes must be predictable to a certain degree. However, the problem is difficult, because the source volume inside the earth is inaccessible to direct observation and because the most important parameter, the stress level, cannot be measured directly. Also, seismology is such a young science that the cause of earthquakes was discovered in the 1960s only. Advanced seismograph networks as well as modern techniques to measure crustal deformations, such as the Global Positioning System (GPS) and the Synthetic Aperture Radar Interferometry technique (InSAR), have come on line only recently, and only in Japan are they deployed with the densities necessary for significant advances in the understanding of the rupture initiation process. In addition, no real program for earthquake prediction research exists in the United States, largely because funding agencies and peer reviewers shy away from a field in which unprofessional, but motivated individuals are active. Although claims of successful predictions are often not justified, a few correct predictions have been made. Most of these had time-windows of years, but some were accurate to days and allowed preparatory actions. To make significant progress, we must learn how to conduct rigorous science in a field where amateurs cannot be discouraged to venture. Leadership is necessary to raise the funding to an adequate level and to involve the best minds in this promising, potentially extremely rewarding, but controversial research topic.

Road Surfaces And Earthquake Engineering: A Theoretical And Experimental Study  

SciTech Connect

As is well known, road surfaces greatly affect vehicle-road interaction. As a consequence, road surfaces have a paramount influence on road safety and pavement management systems. On the other hand, earthquakes produce deformations able to modify road surface structure, properties and performance. In the light of these facts, the main goal of this paper has been confined into the modelling of road surface before, during and after the seismic event. The fundamentals of road surface texture theory have been stated in a general formulation. Models in the field of road profile generation and theoretical properties, before, during and after the earthquake, have been formulated and discussed. Practical applications can be hypothesised in the field of vehicle-road interaction as a result of road surface texture derived from deformations and accelerations caused by seismic or similar events.

Integrated Program of Multidisciplinary Education and Research in Mechanics and Physics of Earthquakes  

NASA Astrophysics Data System (ADS)

Studying earthquake source processes is a multidisciplinary endeavor involving a number of subjects, from geophysics to engineering. As a solid mechanician interested in understanding earthquakes through physics-based computational modeling and comparison with observations, I need to educate and attract students from diverse areas. My CAREER award has provided the crucial support for the initiation of this effort. Applying for the award made me to go through careful initial planning in consultation with my colleagues and administration from two divisions, an important component of the eventual success of my path to tenure. Then, the long-term support directed at my program as a whole - and not a specific year-long task or subject area - allowed for the flexibility required for a start-up of a multidisciplinary undertaking. My research is directed towards formulating realistic fault models that incorporate state-of-the-art experimental studies, field observations, and analytical models. The goal is to compare the model response - in terms of long-term fault behavior that includes both sequences of simulated earthquakes and aseismic phenomena - with observations, to identify appropriate constitutive laws and parameter ranges. CAREER funding has enabled my group to develop a sophisticated 3D modeling approach that we have used to understand patterns of seismic and aseismic fault slip on the Sunda megathrust in Sumatra, investigate the effect of variable hydraulic properties on fault behavior, with application to Chi-Chi and Tohoku earthquake, create a model of the Parkfield segment of the San Andreas fault that reproduces both long-term and short-term features of the M6 earthquake sequence there, and design experiments with laboratory earthquakes, among several other studies. A critical ingredient in this research program has been the fully integrated educational component that allowed me, on the one hand, to expose students from different backgrounds to the multidisciplinary knowledge required for research in my group and, on the other hand, to communicate the field insights to a broader community. Newly developed course on Dynamic Fracture and Frictional Faulting has combined geophysical and engineering knowledge at the forefront of current research activities relevant to earthquake studies and involved students in these activities through team-based course projects. The course attracts students from more than ten disciplines and received a student rating of 4.8/5 this past academic year. In addition, the course on Continuum Mechanics was enriched with geophysical references and examples. My group has also been visiting physics classrooms in a neighboring public school that serve mostly underrepresented minorities. The visits were beneficial not only to the high school students but also for graduate students and postdocs in my group, who got experience in presenting their field in a way accessible for the general public. Overall, the NSF CAREER award program through the Geosciences Directorate (NSF official Eva E. Zanzerkia) has significantly facilitated my development as a researcher and educator and should be either maintained or expanded.

Review of NASA's Hypersonic Research Engine Project  

NASA Technical Reports Server (NTRS)

The goals of the NASA Hypersonic Research Engine (HRE) Project, which began in 1964, were to design, develop, and construct a hypersonic research ramjet/scramjet engine for high performance and to flight-test the developed concept over the speed range from Mach 3 to 8. The project was planned to be accomplished in three phases: project definition, research engine development, and flight test using the X-15A-2 research aircraft, which was modified to carry hydrogen fuel for the research engine. The project goal of an engine flight test was eliminated when the X-15 program was canceled in 1968. Ground tests of engine models then became the focus of the project. Two axisymmetric full-scale engine models having 18-inch-diameter cowls were fabricated and tested: a structural model and a combustion/propulsion model. A brief historical review of the project with salient features, typical data results, and lessons learned is presented.

Stirling Laboratory Research Engine: Preprototype configuration report  

NASA Technical Reports Server (NTRS)

The concept of a simple Stirling research engine that could be used by industrial, university, and government laboratories was studied. The conceptual and final designs, hardware fabrication and the experimental validation of a preprototype stirling laboratory research engine (SLRE) were completed. Also completed was a task to identify the potential markets for research engines of this type. An analytical effort was conducted to provide a stirling cycle computer model. The versatile engine is a horizontally opposed, two piston, single acting stirling engine with a split crankshaft drive mechanism; special instrumentation is installed at all component interfaces. Results of a thermodynamic energy balance for the system are reported. Also included are the engine performance results obtained over a range of speeds, working pressures, phase angles and gas temperatures. The potential for a stirling research engine to support the laboratory requirements of educators and researchers was demonstrated.

The New Madrid earthquakes; an engineering-geologic interpretation of relict liquefaction features  

USGS Publications Warehouse

Earthquake-induced sand blows and sand-filled fissures are present in a belt 40 to 60 km. wide that extends from near Charleston, Mo., southward to about 20 km. south of Marked Tree, Ark. This region of earthquake-induced sand blows and other liquefaction-related features is almost exclusively in the St. Francis Basin, an alluvial lowland that typically has a thin (2 to 8 m thick), clay-bearing topstratum underlain by about 30 to 60 m of unconsolidated sand (the substratum). Liquefaction of the substratum sands has made the sand blows. The sand blows and other liquefaction-related features on the ground surface in the St. Francis Basin are almost certainly results of the New Madrid earthquakes of 1811-12. In this report, geologic and engineering properties of the alluvium are used in combination with a map showing the bounds of the liquefaction-related features to locate approximately the epicentral zones for two of the major shocks: the earthquakes of December 16,1811, and February 7,1812. Properties used for the analysis included the Standard Penetration Resistance of the substratum sands, characteristics of the sand's grain size, thickness of the topstratum, and the thickness of the post-Tertiary alluvium. The method of analysis relies largely on the evaluation of the liquefaction potential of the sands. This is done by using the Standard Penetration Test blow counts and by devising a method that uses all possible combinations of liquefaction potential and a realistic relation between attenuation of earthquake accelerations and distance from the epicenter (or more correctly, energy-release center). Two interpreted 1811-12 energy-release centers generally agree well with zones of seismicity defined by modern, small earthquakes. Bounds on accelerations are placed at the limits of sand blows that were generated by the 1811-12 earthquakes in the St. Francis Basin. Conclusions show how the topstratum thickness, sand size of the substratum, and thickness of alluvium affected the distribution of sand blows in the St. Francis Basin.

Applications of research from the U.S. Geological Survey program, assessment of regional earthquake hazards and risk along the Wasatch Front, Utah  

USGS Publications Warehouse

INTERACTIVE WORKSHOPS: ESSENTIAL ELEMENTS OF THE EARTHQUAKE HAZARDS RESEARCH AND REDUCTION PROGRAM IN THE WASATCH FRONT, UTAH: Interactive workshops provided the forum and stimulus necessary to foster collaboration among the participants in the multidisciplinary, 5-yr program of earthquake hazards reduction in the Wasatch Front, Utah. The workshop process validated well-documented social science theories on the importance of interpersonal interaction, including interaction between researchers and users of research to increase the probability that research will be relevant to the user's needs and, therefore, more readily used. REDUCING EARTHQUAKE HAZARDS IN UTAH: THE CRUCIAL CONNECTION BETWEEN RESEARCHERS AND PRACTITIONERS: Complex scientific and engineering studies must be translated for and transferred to nontechnical personnel for use in reducing earthquake hazards in Utah. The three elements needed for effective translation, likelihood of occurrence, location, and severity of potential hazards, and the three elements needed for effective transfer, delivery, assistance, and encouragement, are described and illustrated for Utah. The importance of evaluating and revising earthquake hazard reduction programs and their components is emphasized. More than 30 evaluations of various natural hazard reduction programs and techniques are introduced. This report was prepared for research managers, funding sources, and evaluators of the Utah earthquake hazard reduction program who are concerned about effectiveness. An overview of the Utah program is provided for those researchers, engineers, planners, and decisionmakers, both public and private, who are committed to reducing human casualties, property damage, and interruptions of socioeconomic systems. PUBLIC PERCEPTIONS OF THE IMPLEMENTATION OF EARTHQUAKE MITIGATION POLICIES ALONG THE WASATCH FRONT IN UTAH: The earthquake hazard potential along the Wasatch Front in Utah has been well defined by a number of scientific and engineering studies. Translated earthquake hazard maps have also been developed to identify areas that are particularly vulnerable to various causes of damage such as ground shaking, surface rupturing, and liquefaction. The implementation of earthquake hazard reduction plans are now under way in various communities in Utah. The results of a survey presented in this paper indicate that technical public officials (planners and building officials) have an understanding of the earthquake hazards and how to mitigate the risks. Although the survey shows that the general public has a slightly lower concern about the potential for economic losses, they recognize the potential problems and can support a number of earthquake mitigation measures. The study suggests that many community groups along the Wasatch Front, including volunteer groups, business groups, and elected and appointed officials, are ready for action-oriented educational programs. These programs could lead to a significant reduction in the risks associated with earthquake hazards. A DATA BASE DESIGNED FOR URBAN SEISMIC HAZARDS STUDIES: A computerized data base has been designed for use in urban seismic hazards studies conducted by the U.S. Geological Survey. The design includes file structures for 16 linked data sets, which contain geological, geophysical, and seismological data used in preparing relative ground response maps of large urban areas. The data base is organized along relational data base principles. A prototype urban hazards data base has been created for evaluation in two urban areas currently under investigation: the Wasatch Front region of Utah and the Puget Sound area of Washington. The initial implementation of the urban hazards data base was accomplished on a microcomputer using dBASE III Plus software and transferred to minicomputers and a work station.

A Bibliometric Analysis of Climate Engineering Research  

NASA Astrophysics Data System (ADS)

The past five years have seen a dramatic increase in the number of media and scientific publications on the topic of climate engineering, or geoengineering, and some scientists are increasingly calling for more research on climate engineering as a possible supplement to climate change mitigation and adaptation strategies. In this context, understanding the current state of climate engineering research can help inform policy discussions and guide future research directions. Bibliometric analysis - the quantitative analysis of publications - is particularly applicable to fields with large bodies of literature that are difficult to summarize by traditional review methods. The multidisciplinary nature of the published literature on climate engineering makes it an ideal candidate for bibliometric analysis. Publications on climate engineering are found to be relatively recent (more than half of all articles during 1988-2011 were published since 2008), include a higher than average percentage of non-research articles (30% compared with 8-15% in related scientific disciplines), and be predominately produced by countries located in the Northern Hemisphere and speaking English. The majority of this literature focuses on land-based methods of carbon sequestration, ocean iron fertilization, and solar radiation management and is produced with little collaboration among research groups. This study provides a summary of existing publications on climate engineering, a perspective on the scientific underpinnings of the global dialogue on climate engineering, and a baseline for quantitatively monitoring the development of climate engineering research in the future.

Scientific Research Database of the 2008 Ms8.0 Wenchuan Earthquake  

NASA Astrophysics Data System (ADS)

Nearly 5 years after the 2008 Ms8.0 Wenchuan Earthquake, the Ms7.0 Lushan earthquake stroke 70km away along the same fault system. Given the tremendous life loss and property damages as well as the short time and distance intervals between the two large magnitude events, the scientific probing into their causing factors and future seismic activities in the nearby region will continue to be in the center of earthquake research in China and even the world for years to come. In the past five years, scientists have made significant efforts to study the Wenchuan earthquake from various aspects using different datasets and methods. Their studies cover a variety of topics including seismogenic environment, earthquake precursors, rupture process, co-seismic phenomenon, hazard relief, reservoir induced seismicity and more. These studies have been published in numerous journals in Chinese, English and many other languages. In addition, 54 books regarding to this earthquake have been published. The extremely diversified nature of all publications makes it very difficult and time-consuming, if not impossible, to sort out information needed by individual researcher in an efficient way. An information platform that collects relevant scientific information and makes them accessible in various ways can be very handy. With this mission in mind, the Earthquake Research Group in the Chengdu University of Technology has developed a website www.wceq.org to attack this target: (1) articles published by major journals and books are recorded into a database. Researchers will be able to find articles by topics, journals, publication dates, authors and keywords e.t.c by a few clicks; (2) to fast track the latest developments, researchers can also follow upon updates in the current month, last 90days, 180 days and 365 days by clicking on corresponding links; (3) the modern communication tools such as Facebook, Twitter and their Chinese counterparts are accommodated in this site to share favorite research information with friends; (4) This site also serves as a bridge between readers and authors by providing messaging boards in many forms; (5) we also track relevant meeting presentations, ongoing researches as well as earthquake-related news; (6) furthermore, we also collect publications of earthquakes in the eastern Tibetan plateau and selected ones from other regions for comparison purpose. After nearly one year of operation, the database has been growing steadily with time and the major functionalities have been well developed and stabilized. Up to August 6 2013, totally 847 papers have been collected in our database. Among them 673, 21 and 153 papers are of Wenchuan, Lushan and Tohoko earthquake in interest, respectively. For the Wenchuan earthquake articles, nearly 10%, 20%, 25%,15%, 15% are of studies in seismogenic environment, precursors, rupture process, hazard relief and aftershocks & coseismic events, respectively. Built upon the ever growing database, the next move would be to do more analysis. One ongoing project would be to collect figures from articles that are of special interest to people in the field. A parallel project will also start to extend the database to include Tibetan Plateau studies.

Earthquake precursory research in western Himalaya based on the multi-parametric geophysical observatory data  

NASA Astrophysics Data System (ADS)

The opening of cracks and influx of fluids in the dilatancy zone of impending earthquake is expected to induce short-term changes in physical/chemical/hydrological properties during earthquake build-up cycle, which should be reflected in time-varying geophysical fields. With this rationale, eleven geophysical parameters are being recorded in continuous mode at the Multi-Parametric Geophysical Observatory (MPGO), in Ghuttu, Garhwal Himalaya, for earthquake precursory research. The critical analysis of various geophysical time series indicates anomalous behavior at few occasions; however, the data is also influenced by many external forces. These external influences are the major deterrent for the isolation of precursory signals. The recent work is focused on the data adoptive techniques to estimate and eliminate effects of solar-terrestrial and hydrological/environmental factors for delimiting the data to identify short-term precursors. Although any significant earthquake is not reported close to the observatory, some weak precursory signals and coseismic changes have been identified in few parameters related to the occurrence of moderate and strong earthquakes.

Physics Education Research in an Engineering Context  

NSDL National Science Digital Library

We report on an ongoing investigation of student understanding in several introductory engineering courses at Hamburg University of Technology. Preliminary results from a first-year electrical engineering course indicate that many students did not gain a conceptual understanding of the material. Some students had difficulty interpreting graphical representations of information or displayed a lack of understanding of basic principles. Specific examples concerning load lines and three-phase systems are used to illustrate how general findings from physics education research can guide investigations of student understanding and the development of curriculum in an introductory engineering context.

Earthquakes in Arkansas and vicinity 1699-2010  

USGS Publications Warehouse

This map summarizes approximately 300 years of earthquake activity in Arkansas. It is one in a series of similar State earthquake history maps. Work on the Arkansas map was done in collaboration with the Arkansas Geological Survey. The earthquake data plotted on the map are from several sources: the Arkansas Geological Survey, the Center for Earthquake Research and Information, the National Center for Earthquake Engineering Research, and the Mississippi Department of Environmental Quality. In addition to earthquake locations, other materials presented include seismic hazard and isoseismal maps and related text. Earthquakes are a legitimate concern in Arkansas and parts of adjacent states. Arkansas has undergone a number of significant felt earthquakes since 1811. At least two of these events caused property damage: a magnitude 4.7 earthquake in 1931, and a magnitude 4.3 earthquake in 1967. The map shows all historical and instrumentally located earthquakes in Arkansas and vicinity between 1811 and 2010. The largest historic earthquake in the vicinity of the State was an intensity XI event, on December 16, 1811; the first earthquake in the New Madrid sequence. This violent event and the earthquakes that followed caused considerable damage to the then sparsely settled region.

Defeating Earthquakes  

NASA Astrophysics Data System (ADS)

The 2004 M=9.2 Sumatra earthquake claimed what seemed an unfathomable 228,000 lives, although because of its size, we could at least assure ourselves that it was an extremely rare event. But in the short space of 8 years, the Sumatra quake no longer looks like an anomaly, and it is no longer even the worst disaster of the Century: 80,000 deaths in the 2005 M=7.6 Pakistan quake; 88,000 deaths in the 2008 M=7.9 Wenchuan, China quake; 316,000 deaths in the M=7.0 Haiti, quake. In each case, poor design and construction were unable to withstand the ferocity of the shaken earth. And this was compounded by inadequate rescue, medical care, and shelter. How could the toll continue to mount despite the advances in our understanding of quake risk? The world's population is flowing into megacities, and many of these migration magnets lie astride the plate boundaries. Caught between these opposing demographic and seismic forces are 50 cities of at least 3 million people threatened by large earthquakes, the targets of chance. What we know for certain is that no one will take protective measures unless they are convinced they are at risk. Furnishing that knowledge is the animating principle of the Global Earthquake Model, launched in 2009. At the very least, everyone should be able to learn what his or her risk is. At the very least, our community owes the world an estimate of that risk. So, first and foremost, GEM seeks to raise quake risk awareness. We have no illusions that maps or models raise awareness; instead, earthquakes do. But when a quake strikes, people need a credible place to go to answer the question, how vulnerable am I, and what can I do about it? The Global Earthquake Model is being built with GEM's new open source engine, OpenQuake. GEM is also assembling the global data sets without which we will never improve our understanding of where, how large, and how frequently earthquakes will strike, what impacts they will have, and how those impacts can be lessened by our actions. Using these global datasets will help to make the model as uniform as possible. The model must be built by scientists in the affected countries with GEM's support, augmented by their insights and data. The model will launch in 2014; to succeed it must be open, international, independent, and continuously tested. But the mission of GEM is not just the likelihood of ground shaking, but also gaging the economic and social consequences of earthquakes, which greatly amplify the losses. For example, should the municipality of Istanbul retrofit schools, or increase its insurance reserves and recovery capacity? Should a homeowner in a high-risk area move or strengthen her building? This is why GEM is a public-private partnership. GEM's fourteen public sponsors and eight non-governmental organization members are standing for the developing world. To extend GEM into the financial world, we draw upon the expertise of companies. GEM's ten private sponsors have endorsed the acquisition of public knowledge over private gain. In a competitive world, this is a courageous act. GEM is but one link in a chain of preparedness: from earth science and engineering research, through groups like GEM, to mitigation, retrofit or relocate decisions, building codes and insurance, and finally to prepared hospitals, schools, and homes. But it is a link that our community can make strong.

Research Skills in a Mechanical Engineering Curriculum  

NSDL National Science Digital Library

All teaching and learning in a university is rooted in research1. On the one hand that is so, because learning to become a researcher is a core objective of University training. However, there are also pedagogic arguments. The understanding of scientific method helps the students to develop a generic approach to problem situations. Students who are exposed to research during their graduate years will be encouraged to develop a questioning and inquiring mind and will be less likely to accept uncritically and passively the "truth" as propounded and handed down in the lecture books and by the professional expert. Several publications on undergraduate research in technology education suggest that research enhances student learning, increases retention, increases enrollment, stimulates critical thinking and directs the students towards a richer innovative culture. In most European engineering curricula, however, learning how to conduct research is reserved for the more advanced students. In the Bologna declaration the European countries agreed to implement a Bachelor-Master structure (3+2 years) as a unifying structure for higher education in Europe. During the first three years of the Bachelor program students focus on fundamental knowledge and basic skills. Students with a bachelor degree can opt for a variety of Master programmes inside or outside their own institution. Usually, the Master programmes are closely linked to a research group. As a consequence, most students get the first opportunity to familiarize themselves with scientific research during the Masters phase6.

7th U.S. / Japan Natural Resources (UJNR) Panel on Earthquake Research: Abstract Volume and Technical Program  

USGS Publications Warehouse

The U.S. / Japan Natural Resources (UJNR) Panel on Earthquake Research promotes advanced study toward a more fundamental understanding of the earthquake process and hazard estimation. The Panel promotes basic and applied research to improve our understanding of the causes and effects of earthquakes and to facilitate the transmission of research results to those who implement hazard reduction measures on both sides of the Pacific and around the world. Meetings are held every other year, and alternate between countries with short presentation on current research and local field trips being the highlights. The 5th Joint Panel meeting was held at Asilomar, California in October, 2004. The technical sessions featured reports on the September 28, 2004 Parkfield, California earthquake, progress on earthquake early warning and rapid post-event assessment technology, probabilistic earthquake forecasting and the newly discovered phenomenon of nonvolcanic tremor. The Panel visited the epicentral region of the M 6.0 Parkfield earthquake and viewed the surface ruptures along the San Andreas Fault. They also visited the San Andreas Fault Observatory at Depth (SAFOD), which had just completed the first phase of drilling into the fault. The 6th Joint Panel meeting was held in Tokushima, Japan in November, 2006. The meeting included very productive exchanges of information on approaches to systematic observation of earthquake processes. Sixty eight technical papers were presented during the meeting on a wide range of subjects, including interplate earthquakes in subduction zones, slow slip and nonvolcanic tremor, crustal deformation, recent earthquake activity and hazard mapping. Through our discussion, we reaffirmed the benefits of working together to achieve our common goal of reducing earthquake hazard, continued cooperation on issues involving densification of observation networks and the open exchange of data among scientific communities. We also reaffirmed the importance of making information public in a timely manner. The Panel visited sites along the east coast of Shikoku that were inundated by the tsunami caused by the 1946 Nankai earthquake where they heard from survivors of the disaster and saw new tsunami shelters and barriers. They also visited the Median Tectonic Line, a major onshore strike-slip fault on Shikoku. The 7th Joint Panel meeting was held in Seattle, Wash., U.S.A. from October 27-30, 2008.

Scientific, Engineering, and Financial Factors of the 1989 Human-Triggered Newcastle Earthquake in Australia  

NASA Astrophysics Data System (ADS)

This presentation emphasizes the dualism of natural resources exploitation and economic growth versus geomechanical pollution and risks of human-triggered earthquakes. Large-scale geoengineering activities, e.g., mining, reservoir impoundment, oil/gas production, water exploitation or fluid injection, alter pre-existing lithostatic stress states in the earth's crust and are anticipated to trigger earthquakes. Such processes of in- situ stress alteration are termed geomechanical pollution. Moreover, since the 19th century more than 200 earthquakes have been documented worldwide with a seismic moment magnitude of 4.5earthquakes increased rapidly. An example of a human-triggered earthquake is the 1989 Newcastle event in Australia that was a result of almost 200 years of coal mining and water over-exploitation, respectively. This earthquake, an Mw=5.6 event, caused more than 3.5 billion U.S. dollars in damage (1989 value) and was responsible for Australia's first and only to date earthquake fatalities. It is therefore thought that, the Newcastle region tends to develop unsustainably if comparing economic growth due to mining and financial losses of triggered earthquakes. An hazard assessment, based on a geomechanical crust model, shows that only four deep coal mines were responsible for triggering this severe earthquake. A small-scale economic risk assessment identifies that the financial loss due to earthquake damage has reduced mining profits that have been re-invested in the Newcastle region for over two centuries beginning in 1801. Furthermore, large-scale economic risk assessment reveals that the financial loss is equivalent to 26% of the Australian Gross Domestic Product (GDP) growth in 1988/89. These costs account for 13% of the total costs of all natural disasters (e.g., flooding, drought, wild fires) and 94% of the costs of all earthquakes recorded in Australia between 1967 and 1999. In conclusion, the increasing number and size of geoengineering activities, such as coal mining near Newcastle or planned carbon dioxide Geosequestration initiatives, represent a growing hazard potential, which can negatively affect socio-economic growth and sustainable development. Finally, hazard and risk degrees, based on geomechanical-mathematical models, can be forecasted in space and over time for urban planning in order to prevent economic losses of human-triggered earthquakes in the future.

Collaborative Engineering for Research and Development  

NASA Technical Reports Server (NTRS)

Research and development (R&D) organizations are being required to be relevant, to be more application-oriented, and to be partners in the strategic management of the business while meeting the same challenges as the rest of the organization, namely: (1) reduced time to market; (2) reduced cost; (3) improved quality; (4) increased reliability; and (5) increased focus on customer needs. Recent advances in computer technology and the Internet have created a new paradigm of collaborative engineering or collaborative product development (CPD), from which new types of relationships among researchers and their partners have emerged. Research into the applicability and benefits of CPD in a low/no production, R&D, and/or government environment is limited. In addition, the supply chain management (SCM) aspects of these relationships have not been studied. This paper presents research conducted at the NASA Glenn Research Center (GRC) investigating the applicability of CPD and SCM in an R&D organization. The study concentrates on the management and implementation of space research activities at GRC. Results indicate that although the organization is engaged in collaborative relationships that incorporate aspects of SCM, a number of areas, such as development of trust and information sharing merit special attention.

Research on the Relation between Anomalous Infrasonic waves and several Earthquakes  

NASA Astrophysics Data System (ADS)

It is well known that earthquakes can generate infrasound signals often detected by infrasound monitoring system. Some of the observations suggest that infrasound with a typical frequency of a few Hz can be generated by vibrating ground surface and propagate at distances of a few thousands kilometers from an earthquake epicenter. In order to receive the anomalous infrasonic waves before earthquakes, we have built three infrasonic monitoring stations in Beijing. And atmospheric pressure is parallel observing at the same time. At first, two infrasonic monitoring equipment was putted in the same station. The data was observed from them has a very good correlation, this means that the performance of the instruments is good. After half a year, three instruments were putted in different stations. Large amounts of data have been acquired and lots of anomalous information has been found before earthquakes, such as Lushan 7.0 earthquake, Okhotsk 8.0 earthquake and Nantou 6.7 earthquake. The anomalous data before three earthquakes is about 7-8days before each earthquake. Moreover, the co-seismic infrasonic waves have been received, which is the similar to seismic wave, so we can know where the earthquake happened through co-seismic infrasonic waves. Using this method, we can inference where the next earthquake will be happened according to the anomalous information. we developed an infrasound generation model for a so-called slow earthquake to show that such kind of earthquake can generate long-period acoustic-gravity waves often observed several days prior to the strong earthquakes. With this model the atmospheric pressure perturbations generated by slow earthquake were calculated, and the occurrence of low frequencies and high amplitudes in the observed signal was explained. A consistency between the results of simulation and observation data indicates that slow earthquake may be a possible source of atmospheric pressure oscillations observed prior to strong earthquakes.

Charles Darwin's earthquake reports  

NASA Astrophysics Data System (ADS)

As it is the 200th anniversary of Darwin's birth, 2009 has also been marked as 170 years since the publication of his book Journal of Researches. During the voyage Darwin landed at Valdivia and Concepcion, Chile, just before, during, and after a great earthquake, which demolished hundreds of buildings, killing and injuring many people. Land was waved, lifted, and cracked, volcanoes awoke and giant ocean waves attacked the coast. Darwin was the first geologist to observe and describe the effects of the great earthquake during and immediately after. These effects sometimes repeated during severe earthquakes; but great earthquakes, like Chile 1835, and giant earthquakes, like Chile 1960, are rare and remain completely unpredictable. This is one of the few areas of science, where experts remain largely in the dark. Darwin suggested that the effects were a result of the rending of strata, at a point not very deep below the surface of the earth' and when the crust yields to the tension, caused by its gradual elevation, there is a jar at the moment of rupture, and a greater movement...'. Darwin formulated big ideas about the earth evolution and its dynamics. These ideas set the tone for the tectonic plate theory to come. However, the plate tectonics does not completely explain why earthquakes occur within plates. Darwin emphasised that there are different kinds of earthquakes ...I confine the foregoing observations to the earthquakes on the coast of South America, or to similar ones, which seem generally to have been accompanied by elevation of the land. But, as we know that subsidence has gone on in other quarters of the world, fissures must there have been formed, and therefore earthquakes...' (we cite the Darwin's sentences following researchspace. auckland. ac. nz/handle/2292/4474). These thoughts agree with results of the last publications (see Nature 461, 870-872; 636-639 and 462, 42-43; 87-89). About 200 years ago Darwin gave oneself airs by the problems which began to discuss only during the last time. Earthquakes often precede volcanic eruptions. According to Darwin, the earthquake-induced shock may be a common mechanism of the simultaneous eruptions of the volcanoes separated by long distances. In particular, Darwin wrote that the elevation of many hundred square miles of territory near Concepcion is part of the same phenomenon, with that splashing up, if I may so call it, of volcanic matter through the orifices in the Cordillera at the moment of the shock;'. According to Darwin the crust is a system where fractured zones, and zones of seismic and volcanic activities interact. Darwin formulated the task of considering together the processes studied now as seismology and volcanology. However the difficulties are such that the study of interactions between earthquakes and volcanoes began only recently and his works on this had relatively little impact on the development of geosciences. In this report, we discuss how the latest data on seismic and volcanic events support the Darwin's observations and ideas about the 1835 Chilean earthquake. The material from researchspace. auckland. ac. nz/handle/2292/4474 is used. We show how modern mechanical tests from impact engineering and simple experiments with weakly-cohesive materials also support his observations and ideas. On the other hand, we developed the mathematical theory of the earthquake-induced catastrophic wave phenomena. This theory allow to explain the most important aspects the Darwin's earthquake reports. This is achieved through the simplification of fundamental governing equations of considering problems to strongly-nonlinear wave equations. Solutions of these equations are constructed with the help of analytic and numerical techniques. The solutions can model different strongly-nonlinear wave phenomena which generate in a variety of physical context. A comparison with relevant experimental observations is also presented.

Virtual earthquake engineering laboratory with physics-based degrading materials on parallel computers  

NASA Astrophysics Data System (ADS)

For the last few decades, we have obtained tremendous insight into underlying microscopic mechanisms of degrading quasi-brittle materials from persistent and near-saintly efforts in laboratories, and at the same time we have seen unprecedented evolution in computational technology such as massively parallel computers. Thus, time is ripe to embark on a novel approach to settle unanswered questions, especially for the earthquake engineering community, by harmoniously combining the microphysics mechanisms with advanced parallel computing technology. To begin with, it should be stressed that we placed a great deal of emphasis on preserving clear meaning and physical counterparts of all the microscopic material models proposed herein, since it is directly tied to the belief that by doing so, the more physical mechanisms we incorporate, the better prediction we can obtain. We departed from reviewing representative microscopic analysis methodologies, selecting out "fixed-type" multidirectional smeared crack model as the base framework for nonlinear quasi-brittle materials, since it is widely believed to best retain the physical nature of actual cracks. Microscopic stress functions are proposed by integrating well-received existing models to update normal stresses on the crack surfaces (three orthogonal surfaces are allowed to initiate herein) under cyclic loading. Unlike the normal stress update, special attention had to be paid to the shear stress update on the crack surfaces, due primarily to the well-known pathological nature of the fixed-type smeared crack model---spurious large stress transfer over the open crack under nonproportional loading. In hopes of exploiting physical mechanism to resolve this deleterious nature of the fixed crack model, a tribology-inspired three-dimensional (3d) interlocking mechanism has been proposed. Following the main trend of tribology (i.e., the science and engineering of interacting surfaces), we introduced the base fabric of solid particle-soft matrix to explain realistic interlocking over rough crack surfaces, and the adopted Gaussian distribution feeds random particle sizes to the entire domain. Validation against a well-documented rough crack experiment reveals promising accuracy of the proposed 3d interlocking model. A consumed energy-based damage model has been proposed for the weak correlation between the normal and shear stresses on the crack surfaces, and also for describing the nature of irrecoverable damage. Since the evaluation of the consumed energy is directly linked to the microscopic deformation, which can be efficiently tracked on the crack surfaces, the proposed damage model is believed to provide a more physical interpretation than existing damage mechanics, which fundamentally stem from mathematical derivation with few physical counterparts. Another novel point of the present work lies in the topological transition-based "smart" steel bar model, notably with evolving compressive buckling length. We presented a systematic framework of information flow between the key ingredients of composite materials (i.e., steel bar and its surrounding concrete elements). The smart steel model suggested can incorporate smooth transition during reversal loading, tensile rupture, early buckling after reversal from excessive tensile loading, and even compressive buckling. Especially, the buckling length is made to evolve according to the damage states of the surrounding elements of each bar, while all other dominant models leave the length unchanged. What lies behind all the aforementioned novel attempts is, of course, the problem-optimized parallel platform. In fact, the parallel computing in our field has been restricted to monotonic shock or blast loading with explicit algorithm which is characteristically feasible to be parallelized. In the present study, efficient parallelization strategies for the highly demanding implicit nonlinear finite element analysis (FEA) program for real-scale reinforced concrete (RC) structures under cyclic loading are proposed.

Engineering for a Changing World: A Roadmap to the Future of Engineering Practice, Research, and Education  

NSDL National Science Digital Library

Powerful forces, including demographics, globalization, and rapidly evolving technologies are driving profound changes in the role of engineering in society. The changing workforce and technology needs of a global knowledge economy are dramatically changing the nature of engineering practice, demanding far broader skills than simply the mastery of scientific and technological disciplines. The growing awareness of the importance of technological innovation to economic competitiveness and national security is demanding a new priority for application-driven basic engineering research. The nonlinear nature of the flow of knowledge between fundamental research and engineering application, the highly interdisciplinary nature of new technologies, and the impact of cyber infrastructure demand new paradigms in engineering research and development. Moreover, challenges such as the off-shoring of engineering jobs, the decline of student interest in scientific and engineering careers, immigration restrictions, and inadequate social diversity in the domestic engineering workforce are also raising serious questions about the adequacy of our current national approach to engineering.

California Earthquakes: Science, Risks, and the Politics of Hazard Mitigation  

NASA Astrophysics Data System (ADS)

"Politics" should be the lead word in the sub-title of this engrossing study of the emergence and growth of the California and federal earthquake hazard reduction infrastructures. Beginning primarily with the 1906 San Francisco earthquake, scientists, engineers, and other professionals cooperated and clashed with state and federal officials, the business community, " boosters," and the general public to create programs, agencies, and commissions to support earthquake research and hazards mitigation. Moreover, they created a "regulatory-state" apparatus that governs human behavior without sustained public support for its creation. The public readily accepts that earthquake research and mitigation are government responsibilities. The government employs or funds the scientists, engineers, emergency response personnel, safety officials, building inspectors, and others who are instrumental in reducing earthquake hazards. This book clearly illustrates how, and why all of this came to pass.

Research program on Indonesian active faults to support the national earthquake hazard assesments  

NASA Astrophysics Data System (ADS)

In mid 2010 an Indonesian team of earthquake scientists published the new Indonesian probabilistic seismic hazard analysis (PSHA) map. The new PSHA map replaced the previous version that is published in 2002. One of the major challenges in developing the new map is that data for many active fault zones in Indonesia is sparse and mapped only at regional scale, thus the input fault parameters for the PSHA introduce unavoidably large uncertainties. Despite the fact that most Indonesian islands are torn by active faults, only Sumatra has been mapped and studied in sufficient details. In other areas, such as Java and Bali, the most populated regions as well as in the east Indonesian region, where tectonic plate configurations are far more complex and relative plate motions are generally higher, many major active faults and plate boundaries are not well mapped and studied. In early 2011, we have initiated a research program to study major active faults in Indonesia together with starting a new graduate study program, GREAT (Graduate Research for Earthquake and Active Tectonics), hosted by ITB (Institute of Technology bandung) and LIPI (Indonesian Institute of Sciences) in partnership with the Australia-Indonesia Facility for Disaster Reduction (AIFDR). The program include acquisition of high-resolution topography and images required for detailed fault mapping, measuring geological slip rates and locating good sites for paleoseismological studies. It is also coupled by seismological study and GPS surveys to measure geodetic slip rates. To study submarine active faults, we collect and incorporate bathymetry and marine geophysical data. The research will be carried out, in part, through masters and Ph.D student theses. in the first four year of program we select several sites for active fault studies, particulary the ones that pose greater risks to society.

The quiet, clean, general aviation turbofan engine and nacelle system was designed and tested. The engine utilized the core of the AiResearch model TFE731-3 engine and incorporated several unique noise- and emissions-reduction features. Components that were successfully adapted to this core include the fan, gearbox, combustor, low-pressure turbine, and associated structure. A highly versatile workhorse nacelle incorporating interchangeable acoustic and hardwall duct liners, showed that large-engine attenuation technology could be applied to small propulsion engines. The application of the mixer compound nozzle demonstrated both performance and noise advantages on the engine. Major performance, emissions, and noise goals were demonstrated.

The Central and Eastern European Earthquake Research Network - CE3RN  

NASA Astrophysics Data System (ADS)

The region of the Central and Eastern Europe is an area characterised by a relatively high seismicity. The active seismogenic structures and the related potentially destructive events are located in the proximity of the political boundaries between several countries existing in the area. An example is the seismic region between the NE Italy (FVG, Trentino-Alto Adige and Veneto), Austria (Tyrol, Carinthia) and Slovenia. So when a destructive earthquake occurs in the area, all the three countries are involved. In the year 2001 the Agencija Republike Slovenije za Okolje (ARSO) in Slovenia, the Department of Mathematics and Geoscience of the University of Trieste (DMG), the OGS (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale) in Italy and the Zentralanstalt fr Meteorologie und Geodynamik (ZAMG) in Austria signed an agreement for the real-time seismological data exchange in the Southeastern Alps region. Soon after the Interreg IIIa Italia-Austria projects "Trans-National Seismological Networks in the South-Eastern Alps" and "FASTLINK" started. The main goal of these projects was the creation of a transfrontier network for the common seismic monitoring of the region for scientific and civil defense purposes. During these years the high quality data recorded by the transfrontier network has been used, by the involved institutions, for their scientific research, for institutional activities and for the civil defense services. Several common international projects have been realized with success. The instrumentation has been continuously upgraded, the installations quality improved as well as the data transmission efficiency. In the 2013 ARSO, DMG, OGS and ZAMG decided to name the cooperative network "Central and Eastern European Earthquake Research Network - CE3RN". The national/regional seismic networks actually involved in the CE3RN network are: Austrian national BB network (ZAMG - OE) Friuli Veneto SP network (OGS - FV) Friuli VG accelerometric network (DMG - RF) NE Italy BB Network, (OGS & DMG - NI) Slovene national BB network (ARSO -SL) South Tyrol BB Network, (ZAMG - SI) HAREIA strong motion stations, (ZAMG & DMG - HA) Starting from the 2001, the CE3RN represents an excellent example of international high quality research infrastructure and the starting point for the enlargement of the transfrontier network to all countries and their seismological institutions of the Central and Eastern Europe region. Furthermore, one of the main goals of the CE3RN is to intensify the cooperation between these institutions through common research activities and preparation of common international projects. The characteristics of the CE3RN will be described along with the examples of some research results and of common projects realized during the first 13 years of network activity.

Experimental Research Progress of the VASIMR Engine  

NASA Astrophysics Data System (ADS)

The Advanced Space Propulsion Laboratory (ASPL) of NASA's Johnson Space Center is performing research on a Variable Specific Impulse MagnetoPlasma Rocket (VASIMR). The VASIMR is a high power, radio frequency (RF) driven magnetoplasma rocket, capable of very high exhaust velocities, > 100 km/s. In addition, its unique architecture allows in- flight mission-optimization of thrust and specific impulse to enhance performance and reduce trip time. A NASA-led research team involving industry, academia and government facilities is pursuing the development of this concept in the United States. The ASPL's experimental research focuses on three major areas: helicon plasma production, ion cyclotron resonant acceleration (ICRA) and plasma expansion in a magnetic nozzle. The VASIMR experiment (VX-10) performs experimental research that demonstrates the thruster concept at a total RF power on the order of 10 kW. A flexible four- magnet system, with a 1.3 Tesla maximum magnetic field strength, is computer controlled to study axial magnetic field profile shape effects. Power generated at 10 - 50 MHz with about 5 kW is used to perform helicon plasma source development. A 3 MHz RF transmitter capable of 100 kW is available for ICRA experiments. The primary diagnostics are: gas mass flow controllers, RF input power, Langmuir probes, Mach probe, retarding potential analyzers (RPA), microwave interferometer, neutral pressure measurements and plasma light emission. In addition, many thermocouples are attached inside the vacuum chamber to measure heat loads around the plasma discharge. Helicon research so far has been done with hydrogen, deuterium, helium, nitrogen, argon, xenon and mixtures of these gases. Optimization studies have been performed with the magnetic field axial profile shape, gas flow rate, gas tube geometry and RF frequency. The highest performing discharges are found with a high magnetic field choke downstream of the helicon antenna. Upwards of a 40% gas utilization is measured. We measure high flow velocities (> ion sound speed) in the exhaust section after the magnetic choke and the velocity increases with the choke field strength. A strong interaction between the neutral gas and the plasma is observed with measurements in the source region, indicating the possible and desirable acceleration of neutrals by the charge exchange process. Heating profiles on the helicon gas tube indicate plasma production profiles. Highlights of the helicon optimization and measurements will be presented and discussed. ICRA experiments have begun, primarily using a helium helicon discharge as a target. Over 4 kW of power has been applied using a simple antenna array. We observe significant effects, plasma density and energy increase, when applying the power near the second harmonic of the helium ion in the magnetic field. These experiments are recent, so further studies and measurements are in progress. The latest results will be highlighted. Plasma flow measurements in the expanding magnetic field of the exhaust are in progress. Some highlights will be discussed, but more of the recent data are presented in another paper in this session.1 REFERENCES 1. Bering, III, EA, et al.

Postseismic Deformation after the 1964 Great Alaskan Earthquake: Collaborative Research with Goddard Space Flight Center  

NASA Technical Reports Server (NTRS)

The purpose of this project was to carry out GPS observations on the Kenai Peninsula, southern Alaska, in order to study the postseismic and contemporary deformation following the 1964 Alaska earthquake. All of the research supported in this grant was carried out in collaboration with Dr. Steven Cohen of Goddard Space Flight Center. The research funding from this grant primarily supported GPS fieldwork, along with the acquisition of computer equipment to allow analysis and modeling of the GPS data. A minor amount of salary support was provided by the PI, but the great majority of the salary support was provided by the Geophysical Institute. After the expiration of this grant, additional funding was obtained from the National Science Foundation to continue the work. This grant supported GPS field campaigns in August 1995, June 1996, May-June and September 1997, and May-June 1998. We initially began the work by surveying leveling benchmarks on the Kenai peninsula that had been surveyed after the 1964 earthquake. Changes in height from the 1964 leveling data to the 1995+ GPS data, corrected for the geoid-ellipsoid separation, give the total elevation change since the earthquake. Beginning in 1995, we also identified or established sites that were suitable for long-term surveying using GPS. In the subsequent annual GPS campaigns, we made regular measurements at these GPS marks, and steadily enhanced our set of points for which cumulative postseismic uplift data were available. From 4 years of Global Positioning System (GPS) measurements, we find significant spatial variations in present-day deformation between the eastern and western Kenai peninsula, Alaska. Sites in the eastern Kenai peninsula and Prince William Sound move to the NNW relative to North America, in the direction of Pacific-North America relative plate motion. Velocities decrease in magnitude from nearly the full plate rate in southern Prince William Sound to about 30 mm/yr at Seward and to about 5 mm/yr near Anchorage. In contrast, sites in the western Kenai peninsula move to the SW, in a nearly trenchward direction, with a velocity of about 20 mm/yr. The data are consistent with the shallow plate interface offshore and beneath the eastern Kenai and Prince William Sound being completely locked or nearly so, with elastic strain accumulation resulting in rapid motion in the direction of relative plate motion of sites in the overriding plate. The velocities of sites in the western Kenai, along strike to the southwest, are opposite in sign with those predicted from elastic strain accumulation. These data are incompatible with a significant locked region in this segment of the plate boundary. Trenchward velocities are found also for some sites in the Anchorage area. We interpret the trenchward velocities as being caused by a continuing postseismic transient from the 1964 great Alaska earthquake.

Contribution of Graduation Thesis Research toward Engineering Education  

NASA Astrophysics Data System (ADS)

Some Japanese universities have been executing engineering design education intended for educational reforms in engineering. However, the Faculty of Engineering at Kyoto University proposes that academic abilities expected in such a curriculum be supplemented with graduation research, experiment subjects, practice subjects, or other programs. Therefore, engineering design education for first- and second-year students is not newly started in the university. To grasp the educational effects of this policy, a questionnaire survey was conducted for seniors who completed the graduation research. The structure of contributions for the graduation research (competence for experts, human relations, and expression) was extracted using factor analysis. Moreover, it was clarified that academic abilities expected in engineering design education are nearly supplemented with graduation research and other types of subjects, including experiments and practice subjects.

Engineering therapeutic processes: from research to commodity  

NASA Astrophysics Data System (ADS)

Three of the most important forces driving medical care are: patient specificity, treatment specificity and the move from discovery to design. Engineers while trained in specificity, efficiency, and design are often not trained in either biology or medical processes. Yet they are increasing critical to medical care. For example, modern medical imaging at US hospitals generates 1 exabyte (10^18 bytes) of data per year clearly beyond unassisted human analysis. It is not desirable to involve engineers in the acquisition, storage and analysis of this data, it is essential. While in the past we have nibbled around the edges of medical care, it is time and perhaps past time to insert ourselves more squarely into medical processes, making them more efficient, more specific and more robust. This requires engineers who understand biology and physicians who are willing to step away from classic medical thinking to try new approaches. But once the idea is proven in a laboratory, it must move into use and then into common practice. This requires additional engineering to make the process robust to noisy data and imprecise practices as well as workflow analysis to get the new technique into operating and treatment rooms. True innovation and true translation will require physicians, engineers, other medical stakeholders and even corporate involvement to take a new, important idea and move it not just to a patient but to all patients.

Heat engine regenerators: Research status and needs  

SciTech Connect

The rapidly oscillating, variable density flows of regenerative heat engines provide a class of poorly understood unsteady flow and heat transfer problems. These problems are not currently amenable to direct experimental resolution. Experiences in engine development and test programs and efforts to develop analysis tools point to the regenerator as a key area of insufficient understanding. Focusing on flow and heat transfer in regenerators, this report discusses similarity parameters for the flows and reviews the experimental data currently available for Stirling analysis. Then a number of experimental results are presented from recent fundamental fluid mechanical and thermal investigations that shed additional light on the functioning of heat engine regenerators. Suggestions are made for approaches for further measurement and analysis efforts.

Steam engine research for solar parabolic dish  

NASA Technical Reports Server (NTRS)

The parabolic dish solar concentrator provides an opportunity to generate high grade energy in a modular system. Most of the capital is projected to be in the dish and its installation. Assurance of a high production demand of a standard dish could lead to dramatic cost reductions. High production volume in turn depends upon maximum application flexibility by providing energy output options, e.g., heat, electricity, chemicals and combinations thereof. Subsets of these options include energy storage and combustion assist. A steam engine design and experimental program is described which investigate the efficiency potential of a small 25 kW compound reheat cycle piston engine. An engine efficiency of 35 percent is estimated for a 700 C steam temperature from the solar receiver.

Seismic Safety Margins Research Program. Regional relationships among earthquake magnitude scales  

SciTech Connect

The seismic body-wave magnitude m{sub b} of an earthquake is strongly affected by regional variations in the Q structure, composition, and physical state within the earth. Therefore, because of differences in attenuation of P-waves between the western and eastern United States, a problem arises when comparing m{sub b}'s for the two regions. A regional m/sub b/ magnitude bias exists which, depending on where the earthquake occurs and where the P-waves are recorded, can lead to magnitude errors as large as one-third unit. There is also a significant difference between m{sub b} and M{sub L} values for earthquakes in the western United States. An empirical link between the m{sub b} of an eastern US earthquake and the M{sub L} of an equivalent western earthquake is given by M{sub L} = 0.57 + 0.92(m{sub b}){sub East}. This result is important when comparing ground motion between the two regions and for choosing a set of real western US earthquake records to represent eastern earthquakes. 48 refs., 5 figs., 2 tabs.

Biomedical engineering: A platform for research and innovation in ultrasound  

NASA Astrophysics Data System (ADS)

An undergraduate or graduate degree in biomedical engineering prepares students to solve problems at the interface between engineering and medicine. Biomedical engineering encompasses evolving areas such as advanced medical imaging for diagnosis and treatment of disease, tissue engineering for designing and manufacturing biological implants for damaged or diseased tissues and organs, and bioinformatics for determining which genes play a major role in health and disease. Biomedical engineering academic programs produce graduates with the ability to pursue successful careers in the biomedical device industry or to obtain advanced degrees leading to careers in biomedical engineering research, medicine, law or business. Biomedical engineering majors take courses in biology, anatomy, physics, chemistry, engineering, mathematics and medical product design and value life-long learning. Students learn to work effectively in interdisciplinary teams comprised of individuals with diverse social, cultural and technical backgrounds. Biomedical engineering is becoming increasingly important in imaging and image-guided research. Some examples of innovative ultrasound technology under development are ultrasound devices to accelerate the dissolution of blood clots, advanced surgical instruments with ultrasound guidance and ultrasound contrast agents for targeted drug delivery. Biomedical engineering is a great career choice for technically minded individuals who endeavor to work on applied problems that are medically relevant.

Deep earthquakes  

SciTech Connect

Earthquakes are often recorded at depths as great as 650 kilometers or more. These deep events mark regions where plates of the earth's surface are consumed in the mantle. But the earthquakes themselves present a conundrum: the high pressures and temperatures at such depths should keep rock from fracturing suddenly and generating a tremor. This paper reviews the research on this problem. Almost all deep earthquakes conform to the pattern described by Wadati, namely, they generally occur at the edge of a deep ocean and define an inclined zone extending from near the surface to a depth of 600 kilometers of more, known as the Wadati-Benioff zone. Several scenarios are described that were proposed to explain the fracturing and slipping of rocks at this depth.

Our intent in this progress report is to provide a summary of the activities pursued by members of the Mechanical Engineering (ME) Department's Engineering Research Program. The Program's mission is to do research for specific applications in mechanical-engineering fields that are of immediate or potential interest to the Laboratory. The FY84 Program comprises nine projects in four thrust areas in the ME Department. The thrust areas are: Surface Measurements and Characterization; Fabrication Technology; Materials Characterization and Behavior; and Computer-Aided Engineering. In the past, our research was supported almost exclusively by weapons programs; recently, however, we significantly increased our involvement in other Laboratory programs as well. In response to this change, we have established new procedures and guidelines for the submission, review, and selection of research proposals.

Aircraft engine noise research in the United States has made considerable progress over the past 10 years for both subsonic and supersonic flight applications. The Advanced Subsonic Technology (AST) Noise Reduction Program started in 1994 and will be completed in 2001 without major changes to program plans and funding levels. As a result, significant progress has been made toward the goal of reducing engine source noise by 6 EPNdB (Effective Perceived Noise level in decibels). This paper will summarize some of the significant accomplishments from the subsonic engine noise research performed over the past 10 years. The review is by no means comprehensive and only represents a sample of major accomplishments.

Research highlights: micro-engineered therapies.  

PubMed

Lab on a chip systems have often focused on diagnostic, chemical, and cell analysis applications, however, more recently the scale and/or precision of micro-engineered systems has been applied in developing new therapies. In this issue we highlight recent work using microfluidic and micro-engineered systems in therapeutic applications. We discuss two approaches that use microfluidic precision to address challenges in filtering blood - to both remove unwanted pathogens and toxins and isolate rare cells of interest that have therapeutic potential. In both cases chemically-modified surfaces, a bioengineered mannose binding lectin on magnetic particles and antibody-functionalized reversibly degradable alginate film, provide the functionality to remove (or isolate) target cells of interest. The third paper we highlight generates microscale gels as protective niches for cell-based therapies. Importantly, the microgels are designed to have controlled porosity but also mechanical rigidity to protect housed therapeutic cells, like mesenchymal stem cells. We expect continued progress in micro- & nano-enabled therapies facilitated by the fabrication of new microstructured materials, precise separations, and closed-loop sensing and drug delivery.

Noise reduction in radon monitoring data using Kalman filter and application of results in earthquake precursory process research  

NASA Astrophysics Data System (ADS)

Monitoring the concentration of radon gas is an established method for geophysical analyses and research, particularly in earthquake studies. A continuous radon monitoring station was implemented in Jooshan hotspring, Kerman province, south east Iran. The location was carefully chosen as a widely reported earthquake-prone zone. A common issue during monitoring of radon gas concentration is the possibility of noise disturbance by different environmental and instrumental parameters. A systematic mathematical analysis aiming at reducing such noises from data is reported here; for the first time, the Kalman filter (KF) has been used for radon gas concentration monitoring. The filtering is incorporated based on several seismic parameters of the area under study. A novel anomaly defined as "radon concentration spike crossing" is also introduced and successfully used in the study. Furthermore, for the first time, a mathematical pattern of a relationship between the radius of potential precursory phenomena and the distance between epicenter and the monitoring station is reported and statistically analyzed.

ARMA models for earthquake ground motions. Seismic safety margins research program  

SciTech Connect

Four major California earthquake records were analyzed by use of a class of discrete linear time-domain processes commonly referred to as ARMA (Autoregressive/Moving-Average) models. It was possible to analyze these different earthquakes, identify the order of the appropriate ARMA model(s), estimate parameters, and test the residuals generated by these models. It was also possible to show the connections, similarities, and differences between the traditional continuous models (with parameter estimates based on spectral analyses) and the discrete models with parameters estimated by various maximum-likelihood techniques applied to digitized acceleration data in the time domain. The methodology proposed is suitable for simulating earthquake ground motions in the time domain, and appears to be easily adapted to serve as inputs for nonlinear discrete time models of structural motions. 60 references, 19 figures, 9 tables.

Sharing Research Models: Using Software Engineering Practices for Facilitation  

PubMed Central

Increasingly, researchers are turning to computational models to understand the interplay of important variables on systems behaviors. Although researchers may develop models that meet the needs of their investigation, application limitationssuch as nonintuitive user interface features and data input specificationsmay limit the sharing of these tools with other research groups. By removing these barriers, other research groups that perform related work can leverage these work products to expedite their own investigations. The use of software engineering practices can enable managed application production and shared research artifacts among multiple research groups by promoting consistent models, reducing redundant effort, encouraging rigorous peer review, and facilitating research collaborations that are supported by a common toolset. This report discusses three established software engineering practices the iterative software development process, object-oriented methodology, and Unified Modeling Languageand the applicability of these practices to computational model development. Our efforts to modify the MIDAS TranStat application to make it more user-friendly are presented as an example of how computational models that are based on research and developed using software engineering practices can benefit a broader audience of researchers.

Strong ground motion data from the 1983 Borah Peak, Idaho earthquake recorded at the Idaho National Engineering Laboratory  

SciTech Connect

The 1983 Borah Peak, Idaho Earthquake was the largest normal faulting event to occur in the last 20 years. There were no near-field recordings of ground motion during the main shock, however, thirteen accelerographs in a permanent array at the Idaho National Engineering Laboratory (INEL) recorded the event at epicentral distances of 90 to 110 km. Peak horizontal accelerations (PGA) recorded at accelerographs above ground-floor level range from 0.037 to 0.187 g. Accelerographs at basement and free-field sites recorded as low as 0.022 g and as high as 0.078 g. Peak vertical accelerations range from 0.016 g at ground level to 0.059 g above ground floor level. A temporary array of digital seismographs deployed by the US Geological Survey (USGS) in the epicentral area recorded ground motion from six large aftershocks at epicentral distances of 4 to 45 km; the largest of these aftershocks also triggered four accelerographs in the INEL array. Two separate analyses were used to estimate near-field ground motion. The first analysis uses the attenuation of the aftershock PGA measurements to extrapolate the INEL main shock PGA measurements into the near-field. This estimates an upper limit of 0.8 g for near-field ground motion. In the second analysis, a set of main shock accelerograms were synthesized. Wave propagation effects were determined from aftershock recordings at one of the USGS portable stations and an INEL seismograph station. These effects were removed from one of the INEL main shock acceleration traces. The synthetic accelerograms were derived for a hypothetical station southwest of Mackay, Idaho. The PGA measured from the synthetic accelerograms were 0.08, 0.14, 0.15, 0.23 g. These estimates correlate well with ground motion expected for an area of Intensity VII.

An International Undergraduate Research Experience in Sustainable Engineering  

NSDL National Science Digital Library

The University of Pittsburghs Swanson School of Engineering (Pitt) recently launched a new International Research Experience for Students Program (IRES) sponsored by the National Science Foundation in sustainable engineering research. The Pitt IRES program presents an innovative international research experience in sustainable design for a select group of undergraduate engineering students who have high potential to pursue graduate education. Interns in the IRES program participate in a 12-week summer internship where they join a multidiscipline research team focused on a complex sustainability problem. Each team is co-led by faculty from the Pitt and the University of Campinas (UNICAMP) in Campinas, So Paolo, Brazil. The first year included eight preparatory weeks in Pittsburgh before traveling to Brazil for four weeks in residence at UNICAMP. The program concludes with the team preparing and presenting a final research report at the end of the summer. Interns have an opportunity to continue in the program for a second year. This paper discusses the experience during and after the first year of the IRES program at Pitt. It also discusses the research conducted during this first year focusing on sustainable drinking water systems. This will be a student-led presentation in which the students discuss their research and experiences with the program.

Earthquake resistant design  

NSDL National Science Digital Library

After having learned about earthquakes in class, through readings and earlier lab assignments, students (in groups of two) are asked to design and construct (using balsa wood, string, paper and glue) a three-story building designed to minimize the effects of shear-wave vibrations that occur during an earthquake. The students are required to research the design concepts on their own and most of the construction work occurs outside of the regular laboratory period. The structures are tested for strength a week before the earthquake occurs - can they support the required load for each floor? On earthquake day, the buildings a tested for a "design earthquake" and then each group is given the opportunity to see how "large" and earthquake their structure can withstand - both in terms of frequency and amplitude variations. In addition to building the structure, each team has to submit a paper reflecting on why they designed and built the structure the way they did.

Cascadia slow slip events and earthquake initiation theories: Hazards research with Plate Boundary Observatory geodetic data (Invited)  

NASA Astrophysics Data System (ADS)

The relationship of transient slow slip events (SSEs) to great earthquakes is a global focus of intense and critical hazards research. Plate Boundary Observatory (PBO) GPS and borehole strainmeter (BSM) networks in the Cascadia forearc provide detailed data that can be compared with simulations predicting how SSEs might evolve as a great earthquake approaches. Cascadia SSEs represent aseismic slip of a few cm in the direction of plate convergence over a period of days or weeks, in a depth range down-dip from the locked zone expected to generate the next great Cascadia subduction earthquake. During an SSE, shear stress borne in the SSE depth range is transferred up-dip at an above-background loading rate. If shear stress on the locked zone is continually accumulating, the daily probability of reaching a threshold failure stress is elevated during an SSE . Alternatively, if dynamic instability is due to rate-weakening fault strength, then SSEs still promote earthquake initiation, but that initiation may be delayed until after the SSE ends, and short-duration SSEs may have negligible effect. In some numerical simulations, great earthquakes could nucleate in the SSE depth range, where effective pressure is assumed to be low. Certain models predict that successive SSEs will slip to increasingly shallower depths, eventually encountering higher effective stress where shear heating can destabilize slip and lead to dynamic rupture. PBO GPS stations have recorded surface deformation from SSEs since inception in 2003; borehole strainmeters (BSMs) have recorded SSE strain signals since 2007. GPS and seismic tremor data show that SSEs reoccur all along the Cascadia subduction zone. An SSE is in progress somewhere in Cascadia much of the time, so the short-term probability increase warranted by a typical SSE is presumably low. We could, however, detect differences among successive SSEs and use criteria informed by the models described above to judge whether a distinctive SSE might represent a higher short-term earthquake probability increase. In all conceptual models, an SSE with more net slip and/or extending further up-dip is more likely to lead to dynamic rupture. There are also models in which faster propagation speed would promote instability by increasing the potential for shear heating. In northernmost Cascadia, BSMs near the coast, up-dip of SSEs, record transient SSE strains at high signal-to-noise ratio. Successive SSEs have differed somewhat in length and propagation speed, but not greatly in up-dip extent or net slip. BSMs up-dip of northern Oregon SSEs have recorded two large SSEs (in 2011 and 2013) having similar strain time series, as well as tremor patterns. In these regions, BSM data could allow an SSE of greater net slip, shallower up-dip extent, or unusual propagation pattern to be identified. Resolution is poorer in reaches of the forearc with BSMs only down-dip of the SSEs. Up-dip BSMs would also be best-positioned to record strain from aseismic slip approaching the locked zone. Some models predict systematic evolution of SSE behavior as a great earthquake approaches, such as decreasing intervals between SSEs, increasing rupture length and slip speed, and slip at successively shallower depths. The northern Cascadia SSEs observed with BSMs since 2007 have not exhibited these patterns, but PBO geodetic instrumentation provides an opportunity to observe them should they develop.

Designing, building, and experimenting with physical simulation models are central problem-solving practices in the engineering sciences. Model-based simulation is an epistemic activity which includes exploration, generation and testing of hypotheses, explanation, and inference. This paper argues that to interpret and understand how these simulation models function in creating knowledge and technologies requires construing problem solving as accomplished by a researcher

Trends in aeropropulsion research and their impact on engineering education  

NASA Technical Reports Server (NTRS)

This presentation is concerned with the trends in aeropropulsion both in the U.S. and abroad and the impact of these trends on the educational process in our universities. In this paper, we shall outline the new directions for research which may be of interest to educators in the aeropropulsion field. Awareness of new emphases, such as emission reductions, noise control, maneuverability, speed, etc., will have a great impact on engineering educators responsible for restructuring courses in propulsion. The information presented herein will also provide some background material for possible consideration in the future development of propulsion courses. In describing aeropropulsion, we are concerned primarily with air-breathing propulsion; however many observations apply equally as well to rocket engine systems. Aeropropulsion research needs are primarily motivated by technologies required for advanced vehicle systems and frequently driven by external requirements such as economic competitiveness, environmental concern and national security. In this presentation, vehicle based research is first described, followed by a discussion of discipline and multidiscipline research necessary to implement the vehicle-focused programs. The importance of collaboration in research and the training of future researchers concludes this presentation.

Research on groundwater radon as a fluid phase precursor to earthquakes  

SciTech Connect

Groundwater radon monitoring work carried out in southern California by the University of Southern California since 1974 is summarized here. This effort began with a sampling network over a locked segment of the San Andreas fault from Tejon to Cajon and was later expanded to cover part of the southern Transverse Mountain ranges. Groundwater samples were brought back weekly to the laboratory for high precision scintillation counting. Needs for more frequent sampling and less labor prompted the development of an economical and field worthy instrument known as the continuous radon monitor. About 10 have been installed in the network since early 1980. The groundwater radon content was found to show anomalous increases (mostly at a single station) before a number of moderate and nearby earthquakes. Our work is hampered by a lack of large earthquakes that may have a regional impact on radon anomalies and by the complexity of the underground hydrological regime. To circumvent this difficulty, we have chosen to monitor only deep artesian wells or hot spring wells.

Estimating surface faulting impacts from the shakeout scenario earthquake  

USGS Publications Warehouse

An earthquake scenario, based on a kinematic rupture model, has been prepared for a Mw 7.8 earthquake on the southern San Andreas Fault. The rupture distribution, in the context of other historic large earthquakes, is judged reasonable for the purposes of this scenario. This model is used as the basis for generating a surface rupture map and for assessing potential direct impacts on lifelines and other infrastructure. Modeling the surface rupture involves identifying fault traces on which to place the rupture, assigning slip values to the fault traces, and characterizing the specific displacements that would occur to each lifeline impacted by the rupture. Different approaches were required to address variable slip distribution in response to a variety of fault patterns. Our results, involving judgment and experience, represent one plausible outcome and are not predictive because of the variable nature of surface rupture. ?? 2011, Earthquake Engineering Research Institute.

Mainland China is situated at the eastern edge of the Eurasian seismic system and is the largest intra-continental region of shallow strong earthquakes in the world. Based on nine earthquakes with magnitudes ranging between 7.0 and 7.9, the book provides observational data and discusses successes and failures of earthquake prediction. Derived from individual earthquakes, observations of various phenomena and seismic activities occurring before and after earthquakes, led to the establishment of some general characteristics valid for earthquake prediction.

Earthquake Myths  

NSDL National Science Digital Library

This site serves to belie several popular myths about earthquakes. Students will learn that most earthquakes do not occur in the early morning and one cannot be swallowed up by an earthquake. In addition, there is no such thing as earthquake weather and California is not falling into the ocean. On the more practical side, students can learn that good building codes do not insure good buildings, it is safer under a table than in a doorway during an earthquake, and most people do not panic during an earthquake.

From biomedical-engineering research to clinical application and industrialization  

NASA Astrophysics Data System (ADS)

The rising costs and aging of the population due to a low birth rate negatively affect the healthcare system in Japan. In 2011, the Council for Science and Technology Policy released the 4th Japan's Science and Technology Basic Policy Report from 2011 to 2015. This report includes two major innovations, 'Life Innovation' and 'Green Innovation', to promote economic growth. Biomedical engineering research is part of 'Life Innovation' and its outcomes are required to maintain people's mental and physical health. It has already resulted in numerous biomedical products, and new ones should be developed using nanotechnology-based concepts. The combination of accumulated knowledge and experience, and 'nanoarchitechtonics' will result in novel, well-designed functional biomaterials. This focus issue contains three reviews and 19 original papers on various biomedical topics, including biomaterials, drug-delivery systems, tissue engineering and diagnostics. We hope that it demonstrates the importance of collaboration among scientists, engineers and clinicians, and will contribute to the further development of biomedical engineering.

Undergraduate Research Co-op in Biomedical Engineering  

NSDL National Science Digital Library

We present our model for expanding a mandatory cooperative education program to include research co-op. We limit the definition of a research co-opto an experiential learning opportunity in academic research laboratory. While we recognize that research experiences can occur in industry, we limit the definition in this way for two reasons. First, any effort to strengthen the nations professorate must begin by exposing undergraduate students to the environment, responsibilities, culture, and demands of the professorate. Second, from an administrative perspective, the process of developing co-op opportunities in academic research labs differs from the process used for industry. We assessed research co-op with respect to traditional industry co-op in terms of administrative overhead and preconceived notions among participants. We also discuss potential pitfalls that face departments seeking to formalize a research co-op program. We demonstrate that research co-ops present several benefits to the students, the engineering program, the university, and to the nation.

Predicting Earthquake Effects  

NASA Astrophysics Data System (ADS)

Advances in the earth sciences and information technology have lead to dramatic improvements in our ability to respond to, as well as anticipate and mitigate, earthquake effects in our communities. The development of Geographic Information System (GIS) based tools such as ShakeMap and HAZUS have ushered in a new era of risk and emergency management. Real-time maps of strong ground motion, coupled with engineering-based descriptions of building and infrastructure inventory and vulnerability enable more accurate determinations of the location and severity of earthquake damage and the socio-economic consequences for emergency managers and officials following significant earthquakes. The ability to map the distribution and growth of seismic risk in the United States has long-term benefits for public policy as well. Long-term forecasts of seismic risk based on varying mitigation strategies can provide guidance for developing national and local earthquake policy. The successful performance of the Trans-Alaska pipeline during the 2002 Denali earthquake illustrates the dependence of performance-based engineering on the ability to predict earthquake effects (e.g., levels of strong ground motion, amounts of fault displacement or ground deformation). Being able to reduce the uncertainty in predicting these parameters has significant economic consequences and enables decision makers to more efficiently prioritize risk management strategies.

Toward ethical norms and institutions for climate engineering research  

NASA Astrophysics Data System (ADS)

Climate engineering (CE), the intentional modification of the climate in order to reduce the effects of increasing greenhouse gas concentrations, is sometimes touted as a potential response to climate change. Increasing interest in the topic has led to proposals for empirical tests of hypothesized CE techniques, which raise serious ethical concerns. We propose three ethical guidelines for CE researchers, derived from the ethics literature on research with human and animal subjects, applicable in the event that CE research progresses beyond computer modeling. The Principle of Respect requires that the scientific community secure the global public's consent, voiced through their governmental representatives, before beginning any empirical research. The Principle of Beneficence and Justice requires that researchers strive for a favorable risk-benefit ratio and a fair distribution of risks and anticipated benefits, all while protecting the basic rights of affected individuals. Finally, the Minimization Principle requires that researchers minimize the extent and intensity of each experiment by ensuring that no experiments last longer, cover a greater geographical extent, or have a greater impact on the climate, ecosystem, or human welfare than is necessary to test the specific hypotheses in question. Field experiments that might affect humans or ecosystems in significant ways should not proceed until a full discussion of the ethics of CE research occurs and appropriate institutions for regulating such experiments are established.

Turkish Compulsory Earthquake Insurance (TCIP)  

NASA Astrophysics Data System (ADS)

Through a World Bank project a government-sponsored Turkish Catastrophic Insurance Pool (TCIP) is created in 2000 with the essential aim of transferring the government's financial burden of replacing earthquake-damaged housing to international reinsurance and capital markets. Providing coverage to about 2.9 Million homeowners TCIP is the largest insurance program in the country with about 0.5 Billion USD in its own reserves and about 2.3 Billion USD in total claims paying capacity. The total payment for earthquake damage since 2000 (mostly small, 226 earthquakes) amounts to about 13 Million USD. The country-wide penetration rate is about 22%, highest in the Marmara region (30%) and lowest in the south-east Turkey (9%). TCIP is the sole-source provider of earthquake loss coverage up to 90,000 USD per house. The annual premium, categorized on the basis of earthquake zones type of structure, is about US90 for a 100 square meter reinforced concrete building in the most hazardous zone with 2% deductible. The earthquake engineering related shortcomings of the TCIP is exemplified by fact that the average rate of 0.13% (for reinforced concrete buildings) with only 2% deductible is rather low compared to countries with similar earthquake exposure. From an earthquake engineering point of view the risk underwriting (Typification of housing units to be insured, earthquake intensity zonation and the sum insured) of the TCIP needs to be overhauled. Especially for large cities, models can be developed where its expected earthquake performance (and consequently the insurance premium) can be can be assessed on the basis of the location of the unit (microzoned earthquake hazard) and basic structural attributes (earthquake vulnerability relationships). With such an approach, in the future the TCIP can contribute to the control of construction through differentiation of premia on the basis of earthquake vulnerability.

Earthquake prediction comes of age  

SciTech Connect

In the last decade, scientists have begun to estimate the long-term probability of major earthquakes along the San Andreas fault. In 1985, the U.S. Geological Survey (USGS) issued the first official U.S. government earthquake prediction, based on research along a heavily instrumented 25-kilometer section of the fault in sparsely populated central California. Known as the Parkfield segment, this section of the Sand Andreas had experienced its last big earthquake, a magnitude 6, in 1966. Estimated probabilities of major quakes along the entire San Andreas by a working group of California earthquake experts, using new geologic data and careful analysis of past earthquakes, are reported.

Integrating Global Hydrology Into Graduate Engineering Education and Research  

NASA Astrophysics Data System (ADS)

Worldwide, polluted water affects the health of 1.2 billion people and contributes to the death of 15 million children under five every year. In addition poor environmental quality contributes to 25 per cent of all preventable ill health in the world. To address some of these problems, at the 2002 World Summit on Sustainable Development, the world community set the goal of halving, by the year 2015, the proportion of people without access to safe drinking water and basic sanitation. Solving sanitation and water resource management problems in any part of the world presents an interdisciplinary, complex challenge. However, when we attempt to solve these problems in an international context, our technical approaches must be tempered with cultural sensitivity and extraordinary management strategies. To meet this challenge, Michigan Tech has developed a unique global partnership with the U.S. Peace Corps to address our acknowledgement of the importance of placing engineering solutions in a global context. The program has graduated 30 students. Program enrollment is now over 30 and over 20 countries have hosted our students. The objective of this presentation is to demonstrate how this unique partnership can be integrated with graduate engineering education and research and also show how such a program may attract a more diverse student population into engineering. All graduate students enrolled in our Master's International Program in Civil and Environmental Engineering must complete specific coursework requirements before departing for their international experience. In CE5993 (Field Engineering in the Developing World) students learn to apply concepts of sustainable development and appropriate technology in the developing world. In FW5770 (Rural Community Development Planning and Analysis) students learn how one involves a community in the decision making process. A common theme in both courses is the role of woman in successful development projects. Technical specialization allows a student to take coursework in hydrology, water planning and management, and water quality engineering. The 2-3 semester residence on campus is then followed by three months of cultural, language, and technical training with the Peace Corps. After training students complete two years of service in the Peace Corps, typically working as a water/sanitation engineer while also completing a research project related to their Peace Corps experience. Some unique aspects of the Peace Corps experience is that it provides students with cultural awareness, language proficiency, community organizing skills, skills in consensus building and sustainable development, appreciation for technology that is economically and culturally sensitive, and a long-term field experience to develop an indepth overseas research project. Perhaps one of the greatest aspects of the Peace Corps experience is it provides students a basis to consider the social, economic, and environmental limitations of water projects in the developing world. Some examples of research projects that have been integrated into this program are: (a) culturally appropriate watershed planning and management, (b) technical capacity building of water supply systems, and (c) life cycle thinking approach applied to water and sanitation projects.

Research and engineering assessment of biological solubilization of phosphate  

SciTech Connect

This research and engineering assessment examined a microbial phosphate solubilization process as a method of recovering phosphate from phosphorus containing ore compared to the existing wet acid and electric arc methods. A total of 860 microbial isolates, collected from a range of natural environments were tested for their ability to solubilize phosphate from rock phosphate. A bacterium (Pseudomonas cepacia) was selected for extensive characterization and evaluation of the mechanism of phosphate solubilization and of process engineering parameters necessary to recover phosphate from rock phosphate. These studies found that concentration of hydrogen ion and production of organic acids arising from oxidation of the carbon source facilitated microbial solubilization of both pure chemical insoluble phosphate compounds and phosphate rock. Genetic studies found that phosphate solubilization was linked to an enzyme system (glucose dehydrogenase). Process-related studies found that a critical solids density of 1% by weight (ore to liquid) was necessary for optimal solubilization. An engineering analysis evaluated the cost and energy requirements for a 2 million ton per year sized plant, whose size was selected to be comparable to existing wet acid plants.

Glacial earthquakes.  

PubMed

We have detected dozens of previously unknown, moderate earthquakes beneath large glaciers. The seismic radiation from these earthquakes is depleted at high frequencies, explaining their nondetection by traditional methods. Inverse modeling of the long-period seismic waveforms from the best-recorded earthquake, in southern Alaska, shows that the seismic source is well represented by stick-slip, downhill sliding of a glacial ice mass. The duration of sliding in the Alaska earthquake is 30 to 60 seconds, about 15 to 30 times longer than for a regular tectonic earthquake of similar magnitude. PMID:14512505

User guide to the Burner Engineering Research Laboratory  

SciTech Connect

The Burner Engineering Research Laboratory (BERL) was established with the purpose of providing a facility where manufacturers and researchers can study industrial natural gas burners using conventional and laser-based diagnostics. To achieve this goal, an octagonal furnace enclosure with variable boundary conditions and optical access that can accommodate burners with firing rates up to 2.5 MMBtu per hour was built. In addition to conventional diagnostic capabilities like input/output measurements, exhaust gas monitoring, suction pyrometry and in-furnace gas sampling, laser-based diagnostics available at BERL include planar Mie scattering, laser Doppler velocimetry and laser-induced fluorescence. This paper gives an overview of the operation of BERL and a description of the diagnostic capabilities and an estimate of the time required to complete each diagnostic for the potential user who is considering submitting a proposal.

Accessing Current, Recent and Historical Earthquake Data  

NSDL National Science Digital Library

This site explains the many Internet tools that are currently available for accessing earthquake data. Students discover that by using these tools one can obtain information (such as location, origin time and magnitude) about the most recent earthquakes; search historical earthquake catalogs for earthquakes in a given region over a selected time period; and view, download or make maps of recent or historical earthquake activity of the world or of a selected region. They also learn that the tools support education and research activities related to earthquakes such as: maintaining a classroom map of significant earthquakes; calculating earthquake magnitude from educational seismograph records and comparing with official magnitude estimates; obtaining historical earthquake data for a specific area to relate a recent event to the background seismicity; and analyzing sequences of earthquake activity. There is a link to information about obtaining and using seismograms.

Young Engineers & Scientists (YES) - Engaging Teachers in Space Research  

NASA Astrophysics Data System (ADS)

The Young Engineers and Scientists (YES) Program is a community partnership between Southwest Research Institute (SwRI) and local high schools in San Antonio. It provides talented high school juniors and seniors a bridge between classroom instruction and real world, research experiences in physical sciences, information sciences, and engineering. YES consists of two parts: 1) An intensive three-week summer workshop held at SwRI where students experience the research environment first-hand; develop skills and acquire tools for solving scientific problems, attend mini-courses and seminars on electronics, C++ programming, the Internet, careers, science ethics, social impact of technology, and other topics; and select their individual research project with their mentor (SwRI staff member) to be completed during the academic year; and 2) A collegial mentorship where students complete individual research projects under the guidance of their mentors and teachers during the academic year and earn honors credit. At the end of the school year, students publicly present and display their work, acknowledging their accomplishments and spreading career awareness to other students and teachers. YES has been highly successful during the past nineteen (19) years. A total of 258 students have completed or are currently enrolled in YES. Of these students, 38% are females and 57% are ethnic minorities, reflecting the local diversity of the San Antonio area. All YES graduates have entered college, several work or have worked for SwRI, two businesses have formed, and three scientific publications have resulted. Sixteen (16) teacher participants have attended the YES workshop and have developed classroom materials based on their experiences in research at SwRI in the past three (3) years. In recognition of its excellence, YES received the Celebrate Success in 1996 and the Outstanding Campus Partner-of-the-Year Award in 2005, both from Northside Independent School District (San Antonio, Texas). Acknowledgments: We are grateful for support from the NASA MMS Mission E/PO Grant, SwRI, Northside Independent School District, and local charitable foundations.

Research on the February 18, 1996 earthquake in the caves of Saint-Paul-de-Fenouillet area, (eastern Pyrenees, France)  

NASA Astrophysics Data System (ADS)

Eight caves have been investigated near Saint-Paul-de-Fenouillet after the earthquake of 5.2 magnitude of February 1996 which occurred in the eastern Pyrenees (France) and caused moderate damage at the ground surface. The earthquake has been associated with the movement of an E-W fault. The caves had not been visited since the earthquake. Some damage, mainly collapses of soda straws and small rocks, could be attributed to this earthquake. The most interesting cave in the epicentral area is the Paradet cave which is situated on a recently activated fault plane. In this cave, soda straw falls could be attributed to the earthquake, but other more ancient damage was also observed. Analysis of the azimuth of fallen speleothems, which are natural pendulums, may indicate the directions, and an estimation of their mechanical properties gives the threshold of the seismic ground motion amplitude responsible for their collapse, thus supplying information to calibrate damage due to past earthquakes. A statistical study indicates that the main direction of the collapsed soda straws is E-W. Numerical simulations confirm that soda straws are relatively strong objects that may break under certain conditions during earthquakes.

The 1868 Hayward Earthquake Alliance: A Case Study - Using an Earthquake Anniversary to Promote Earthquake Preparedness  

NASA Astrophysics Data System (ADS)

Last October 21st marked the 140th anniversary of the M6.8 1868 Hayward Earthquake, the last damaging earthquake on the southern Hayward Fault. This anniversary was used to help publicize the seismic hazards associated with the fault because: (1) the past five such earthquakes on the Hayward Fault occurred about 140 years apart on average, and (2) the Hayward-Rodgers Creek Fault system is the most likely (with a 31 percent probability) fault in the Bay Area to produce a M6.7 or greater earthquake in the next 30 years. To promote earthquake awareness and preparedness, over 140 public and private agencies and companies and many individual joined the public-private nonprofit 1868 Hayward Earthquake Alliance (1868alliance.org). The Alliance sponsored many activities including a public commemoration at Mission San Jose in Fremont, which survived the 1868 earthquake. This event was followed by an earthquake drill at Bay Area schools involving more than 70,000 students. The anniversary prompted the Silver Sentinel, an earthquake response exercise based on the scenario of an earthquake on the Hayward Fault conducted by Bay Area County Offices of Emergency Services. 60 other public and private agencies also participated in this exercise. The California Seismic Safety Commission and KPIX (CBS affiliate) produced professional videos designed forschool classrooms promoting Drop, Cover, and Hold On. Starting in October 2007, the Alliance and the U.S. Geological Survey held a sequence of press conferences to announce the release of new research on the Hayward Fault as well as new loss estimates for a Hayward Fault earthquake. These included: (1) a ShakeMap for the 1868 Hayward earthquake, (2) a report by the U. S. Bureau of Labor Statistics forecasting the number of employees, employers, and wages predicted to be within areas most strongly shaken by a Hayward Fault earthquake, (3) new estimates of the losses associated with a Hayward Fault earthquake, (4) new ground motion simulations of a Hayward Fault earthquake, (5) a new USGS Fact Sheet about the earthquake and the Hayward Fault, (6) a virtual tour of the 1868 earthquake, and (7) a new online field trip guide to the Hayward Fault using locations accessible by car and public transit. Finally, the California Geological Survey and many other Alliance members sponsored the Third Conference on Earthquake Hazards in the East Bay at CSU East Bay in Hayward for the three days following the 140th anniversary. The 1868 Alliance hopes to commemorate the anniversary of the 1868 Hayward Earthquake every year to maintain and increase public awareness of this fault, the hazards it and other East Bay Faults pose, and the ongoing need for earthquake preparedness and mitigation.

Hidden earthquakes  

SciTech Connect

Seismologists generally look for earthquakes to happen along visible fault lines, e.g., the San Andreas fault. The authors maintain that another source of dangerous quakes has been overlooked: the release of stress along a fault that is hidden under a fold in the earth's crust. The paper describes the differences between an earthquake which occurs on a visible fault and one which occurs under an anticline and warns that Los Angeles greatest earthquake threat may come from a small quake originating under downtown Los Angeles, rather than a larger earthquake which occurs 50 miles away at the San Andreas fault.

USEMS & GLASS: investigator-driven frontier research in earthquake physics. Ground-breaking research in Europe enhances outreach to the general public  

NASA Astrophysics Data System (ADS)

USEMS and GLASS are two projects financed by the European Research Council (ERC) as part of the ERC starting grants scheme within the FP7 framework. The rationale behind the funding scheme is to support some of the most promising scientific endeavours in Europe that are being led by young researchers, and to emphasize the excellence of individual ideas rather than specific research areas; in other words, to promote bottom-up frontier research. The general benefits of this rationale are evident in the two ongoing projects that deal with earthquake physics, as these projects are increasingly recognized in their scientific community. We can say that putting excellence at the heart of European Research strongly contributes to the construction of a European knowledge-based society. From a researcher point-of-view one of the most challenging aspects of these projects is to approach and convey the results of the projects to a general public, contributing to the construction of knowledge-based society. Luckily, media interest and the availability of a number of new communication tools facilitate the outreach of scientific achievements. The largest earthquakes during the last ten years (e.g. Sumatra 2004 and Japan 2011) have received widespread attention in the media world (TV, W.W.W., Newspaper and so on) for months, and successful research projects such as those above also become media protagonists, gaining their space in the media bullring. The USEMS principal investigator and his team have participated in several dissemination events in the Mass Media, such as interviews wit Italian and French TV national broadcasts (RAI Due TG2, RAI Uno Unomattina, Rai Tre Geo & Geo, FRANCE 2); interviews in scientific journals: SCIENCE (Sept. 2010), newspapers and web (Corriere della Sera, Il Gazzettino, Il Messagero, La Stampa, Libero, Il Mattino, Yahoo, ANSA, AdnKronos and AGI); radio (RadioRai Uno, RadioRai Tre Scienza); documentary "Die Eroberung der Alpen" produced by Tangram Film (Munchen, Germany). The USEMS project started in June 2008, and the GLASS project in October 2010. For both projects we developed a number of web pages through the official web site of the host institution, the National Institute of Geophysics and Volcanology (INGV) in Rome. In these pages we describe the projects, publish pictures and short-movies of the experimental activities and keep the project results up to date. In addition the research teams collaborate within various INGV outreach schemes (school and student visits in the laboratory, writing short news reports for the INGV press office, and interviews with journalists) as well as using WWW channels (Facebook, Youtube) to make the project results available to the general public. Finally, it is notable that the ERC funding agency itself is fully involved in the outreach activities using its own communication channels and its highly skilled resources which promote through brochures, web pages, publications and documentaries the best projects. We are going to improve our effort in this direction up to the end of the projects.

SR-71 Research Engineer Marta Bohn-Meyer  

NASA Technical Reports Server (NTRS)

This 1992 photo shows SR-71 flight engineer Marta Bohn-Meyer in front of one of NASA's SR-71 aircraft on the ramp at the Ames-Dryden Flight Research Facility (later, Dryden Flight Research Center), Edwards, California. An aerospace engineer who has been at Dryden since 1979, Bohn-Meyer is the first female crew member ever assigned to fly in the SR-71. Data from the SR-71 program carried out by NASA will be used to aid designers of future supersonic aircraft and propulsion systems. Two SR-71 aircraft have been used by NASA as testbeds for high-speed and high-altitude aeronautical research. The aircraft, an SR-71A and an SR-71B pilot trainer aircraft, have been based here at NASA's Dryden Flight Research Center, Edwards, California. They were transferred to NASA after the U.S. Air Force program was cancelled. As research platforms, the aircraft can cruise at Mach 3 for more than one hour. For thermal experiments, this can produce heat soak temperatures of over 600 degrees Fahrenheit (F). This operating environment makes these aircraft excellent platforms to carry out research and experiments in a variety of areas -- aerodynamics, propulsion, structures, thermal protection materials, high-speed and high-temperature instrumentation, atmospheric studies, and sonic boom characterization. The SR-71 was used in a program to study ways of reducing sonic booms or over pressures that are heard on the ground, much like sharp thunderclaps, when an aircraft exceeds the speed of sound. Data from this Sonic Boom Mitigation Study could eventually lead to aircraft designs that would reduce the 'peak' overpressures of sonic booms and minimize the startling affect they produce on the ground. One of the first major experiments to be flown in the NASA SR-71 program was a laser air data collection system. It used laser light instead of air pressure to produce airspeed and attitude reference data, such as angle of attack and sideslip, which are normally obtained with small tubes and vanes extending into the airstream. One of Dryden's SR-71s was used for the Linear Aerospike Rocket Engine, or LASRE Experiment. Another earlier project consisted of a series of flights using the SR-71 as a science camera platform for NASA's Jet Propulsion Laboratory in Pasadena, California. An upward-looking ultraviolet video camera placed in the SR-71's nosebay studied a variety of celestial objects in wavelengths that are blocked to ground-based astronomers. Earlier in its history, Dryden had a decade of past experience at sustained speeds above Mach 3. Two YF-12A aircraft and an SR-71 designated as a YF-12C were flown at the center between December 1969 and November 1979 in a joint NASA/USAF program to learn more about the capabilities and limitations of high-speed, high-altitude flight. The YF-12As were prototypes of a planned interceptor aircraft based on a design that later evolved into the SR-71 reconnaissance aircraft. Dave Lux was the NASA SR-71 project manger for much of the decade of the 1990s, followed by Steve Schmidt. Developed for the USAF as reconnaissance aircraft more than 30 years ago, SR-71s are still the world's fastest and highest-flying production aircraft. The aircraft can fly at speeds of more than 2,200 miles per hour (Mach 3+, or more than three times the speed of sound) and at altitudes of over 85,000 feet. The Lockheed Skunk Works (now Lockheed Martin) built the original SR-71 aircraft. Each aircraft is 107.4 feet long, has a wingspan of 55.6 feet, and is 18.5 feet high (from the ground to the top of the rudders, when parked). Gross takeoff weight is about 140,000 pounds, including a possible fuel weight of 80,280 pounds. The airframes are built almost entirely of titanium and titanium alloys to withstand heat generated by sustained Mach 3 flight. Aerodynamic control surfaces consist of all-moving vertical tail surfaces, ailerons on the outer wings, and elevators on the trailing edges between the engine exhaust nozzles. The two SR-71s at Dryden have been assigned the following NASA tail numbers: NASA 844 (A model), military serial 61-79

Ethical issues in engineering models: an operations researcher's reflections.  

PubMed

This article starts with an overview of the author's personal involvement--as an Operations Research consultant--in several engineering case-studies that may raise ethical questions; e.g., case-studies on nuclear waste, water management, sustainable ecology, military tactics, and animal welfare. All these case studies employ computer simulation models. In general, models are meant to solve practical problems, which may have ethical implications for the various stakeholders; namely, the modelers, the clients, and the public at large. The article further presents an overview of codes of ethics in a variety of disciples. It discusses the role of mathematical models, focusing on the validation of these models' assumptions. Documentation of these model assumptions needs special attention. Some ethical norms and values may be quantified through the model's multiple performance measures, which might be optimized. The uncertainty about the validity of the model leads to risk or uncertainty analysis and to a search for robust models. Ethical questions may be pressing in military models, including war games. However, computer games and the related experimental economics may also provide a special tool to study ethical issues. Finally, the article briefly discusses whistleblowing. Its many references to publications and websites enable further study of ethical issues in modeling. PMID:20535643

Earthquake Precursors in Thermal Infrared Data  

NASA Astrophysics Data System (ADS)

As part of an agreement between NASA and the Arab Youth Venture Foundation (AYVF), three engineering students from the United Arab Emirates (UAE) participated in a 10-week experiential learning program this summer. This educational program is managed by the NASA Ames Research Center Office of Education and Public Outreach and is administered by the Education Associates Program (EAP). One of the research projects under this program tested the hypothesis that signals emitted by the Earths surface prior to the occurrence of an earthquake, including thermal infrared (TIR) emissions, can be detected through appropriate analysis of data collected by the Moderate-resolution Imaging Spectroradiometer (MODIS) satellite sensors. After applying a set of preprocessing algorithms to the satellite data, we analyzed MODIS images showing the TIR emitted by a ground area in the days prior to an eventual earthquake. We used computing tools and software, such as MATLAB and ENVI, to isolate these pre-seismic signals from the background noise. The development of a technique to monitor pre-seismic signals holds promise in finding a method to predict earthquakes.

Software Engineering Research/Developer Collaborations (C104)  

NASA Technical Reports Server (NTRS)

The goal of this collaboration was to produce Flight Software Branch (FSB) process standards for software inspections which could be used across three new missions within the FSB. The standard was developed by Dr. Forrest Shull (Fraunhofer Center for Experimental Software Engineering, Maryland) using the Perspective-Based Inspection approach, (PBI research has been funded by SARP) , then tested on a pilot Branch project. Because the short time scale of the collaboration ruled out a quantitative evaluation, it would be decided whether the standard was suitable for roll-out to other Branch projects based on a qualitative measure: whether the standard received high ratings from Branch personnel as to usability and overall satisfaction. The project used for piloting the Perspective-Based Inspection approach was a multi-mission framework designed for reuse. This was a good choice because key representatives from the three new missions would be involved in the inspections. The perspective-based approach was applied to produce inspection procedures tailored for the specific quality needs of the branch. The technical information to do so was largely drawn through a series of interviews with Branch personnel. The framework team used the procedures to review requirements. The inspections were useful for indicating that a restructuring of the requirements document was needed, which led to changes in the development project plan. The standard was sent out to other Branch personnel for review. Branch personnel were very positive. However, important changes were identified because the perspective of Attitude Control System (ACS) developers had not been adequately represented, a result of the specific personnel interviewed. The net result is that with some further work to incorporate the ACS perspective, and in synchrony with the roll out of independent Branch standards, the PBI approach will be implemented in the FSB. Also, the project intends to continue its collaboration with the technology provider (Dr. Forrest Shull) past the end of the grant, to allow a more rigorous quantitative evaluation.

Does knowledge signify protection? The SEISMOPOLIS centre for improvement of behavior in case of an earthquake  

NASA Astrophysics Data System (ADS)

It is vastly accepted that earthquake education is the way to earthquake protection. Nonetheless experience demonstrates that knowing what to do does not necessarily result in a better behaviour in case of a real earthquake. A research project titled: "Seismopolis" - "Pilot integrated System for Public Familiarization with Earthquakes and Information on Earthquake Protection" aimed at the improvement of the behaviour of people through an appropriate amalgamation of knowledge transfer and virtually experiencing an earthquake situation. Seismopolis combines well established education means such as books and leaflets with new technologies like earthquake simulation and virtual reality. It comprises a series of 5 main spaces that the visitor passes one-by-one. Space 1. Reception and introductory information. Visitors are given fundamental information on earthquakes and earthquake protection, as well as on the appropriate behaviour in case of an earthquake. Space 2. Earthquake simulation room Visitors experience an earthquake in a room. A typical kitchen is set on a shake table area (3m x 6m planar triaxial shake table) and is shaken in both horizontal and vertical directions by introducing seismographs of real or virtual earthquakes. Space 3. Virtual reality room Visitors may have the opportunity to virtually move around in the building or in the city after an earthquake disaster and take action as in a real-life situation, wearing stereoscopic glasses and using navigation tools. Space 4. Information and resources library Visitors are offered the opportunity to know more about earthquake protection. A series of means are available for this, some developed especially for Seismopolis (3 books, 2 Cds, a website and an interactive table game). Space 5. De-briefing area Visitors may be subjected to a pedagogical and psychological evaluation at the end of their visit and offered support if needed. For the evaluation of the "Seismopolis" Centre, a pilot application of the complete complex took place with the participation of different groups (schoolchildren, university students, adults, elderly persons, emigrants and persons with special needs). This test period recorded positive impression and reaction from the visitors and indicated the pedagogical and psychological appropriateness of the system. Seismopolis is the outcome of collaboration of public, academic and private partners and of a range of disciplines, namely seismologists, geologists, structural engineers, geographers, sociologists and psycologists. It is actually hosted by the Municipality of Rendis in Athens. More information on Seismopolis can be found in www.seismopolis.org .

Research on hypersonic aircraft using pre-cooled turbojet engines  

NASA Astrophysics Data System (ADS)

Systems analysis of a Mach 5 class hypersonic aircraft is performed. The aircraft can fly across the Pacific Ocean in 2 h. A multidisciplinary optimization program for aerodynamics, structure, propulsion, and trajectory is used in the analysis. The result of each element model is improved using higher accuracy analysis tools. The aerodynamic performance of the hypersonic aircraft is examined through hypersonic wind tunnel tests. A thermal management system based on the data of the wind tunnel tests is proposed. A pre-cooled turbojet engine is adopted as the propulsion system for the hypersonic aircraft. The engine can be operated continuously from take-off to Mach 5. This engine uses a pre-cooling cycle using cryogenic liquid hydrogen. The high temperature inlet air of hypersonic flight would be cooled by the same liquid hydrogen used as fuel. The engine is tested under sea level static conditions. The engine is installed on a flight test vehicle. Both liquid hydrogen fuel and gaseous hydrogen fuel are supplied to the engine from a tank and cylinders installed within the vehicle. The designed operation of major components of the engine is confirmed. A large amount of liquid hydrogen is supplied to the pre-cooler in order to make its performance sufficient for Mach 5 flight. Thus, fuel rich combustion is adopted at the afterburner. The experiments are carried out under the conditions that the engine is mounted upon an experimental airframe with both set up either horizontally or vertically. As a result, the operating procedure of the pre-cooled turbojet engine is demonstrated.

Earthquake Location  

NSDL National Science Digital Library

Earthquake location is an interesting and significant aspect of seismology. Locating earthquakes is necessary for compiling useful seismicity information, calculating magnitudes, and study of fault zones, Earth structure and the earthquake process. Methods of earthquake location involve understanding of seismic waves, wave propagation, interpretation of seismograms, Earth velocity structure, triangulation, and the concepts (and mathematics) of inverse problems. Because earthquake location can be approached with relatively simple to very complex methods, it can be included in various levels of educational curricula and for "in-depth" study. Progressively developing a deep understanding of concepts, computational techniques and applications (and the capabilities, limitations and uncertainties of these applications) is a characteristic of science and an opportunity to "learn science by doing science." A number of methods that vary from simple to complex are available for learning about earthquake location. The methods also allow connections to other important concepts in seismology and provide a variety of approaches that address different learning styles and can be used for reinforcement and assessment.

Earthquake and ambient vibration monitoring of the steel-frame UCLA factor building  

USGS Publications Warehouse

Dynamic property measurements of the moment-resisting steel-frame University of California, Los Angeles, Factor building are being made to assess how forces are distributed over the building. Fourier amplitude spectra have been calculated from several intervals of ambient vibrations, a 24-hour period of strong winds, and from the 28 March 2003 Encino, California (ML = 2.9), the 3 September 2002 Yorba Linda, California (ML = 4.7), and the 3 November 2002 Central Alaska (Mw = 7.9) earthquakes. Measurements made from the ambient vibration records show that the first-mode frequency of horizontal vibration is between 0.55 and 0.6 Hz. The second horizontal mode has a frequency between 1.6 and 1.9 Hz. In contrast, the first-mode frequencies measured from earthquake data are about 0.05 to 0.1 Hz lower than those corresponding to ambient vibration recordings indicating softening of the soil-structure system as amplitudes become larger. The frequencies revert to pre-earthquake levels within five minutes of the Yorba Linda earthquake. Shaking due to strong winds that occurred during the Encino earthquake dominates the frequency decrease, which correlates in time with the duration of the strong winds. The first shear wave recorded from the Encino and Yorba Linda earthquakes takes about 0.4 sec to travel up the 17-story building. ?? 2005, Earthquake Engineering Research Institute.

Consequently, the purposes of this study are as follows: (1) to gain an understanding of the workload policies associated with the engineering and engineering technology disciplines at public doctoral and research universities, (2) to determine the extent by which such policies have provisions for reducing or increasing course load, and (3) to determine administrator and faculty preference for the inclusion of "flexible elements" in a policy, and if such preference can be linked to various demographic, career, and research related attributes. A number of literature sources were consulted in an effort to obtain the background needed for this study including ERIC documents, periodical literature, past dissertations, and books. In addition, the literature section contains information reflecting analyses performed on data retrieved from the 1993 National Study of Postsecondary Faculty. Three types of data were collected for the study: (1) surveys, (2) documented workload policies, and (3) case study interviews. The data were obtained from public doctoral and research universities which have engineering and engineering technology programs accredited by the Accreditation Board for Engineering and Technology. As a result of the study, it was determined that the majority of public doctoral and research universities have written workload policies at either the university level or at the department level. Unwritten policies also exist, but for many institutions, classification of the policies by the deans and chairs differ. The majority of workload policies contain provisions for reducing course load, however, only a small percentage of the policies contain provisions for increasing course load. The frequency of use of reduced course load provisions is greater than the frequency of use of increased course load provisions. Research results indicate that administrators and faculty desire workload policies which contain "flexible elements." In addition, a substantial percentage of faculty stated that they would prefer to teach a greater load for a stated period of time in lieu of performing advisement, research, or service.

Software Engineering Research/Developer Collaborations in 2005  

NASA Technical Reports Server (NTRS)

In CY 2005, three collaborations between software engineering technology providers and NASA software development personnel deployed three software engineering technologies on NASA development projects (a different technology on each project). The main purposes were to benefit the projects, infuse the technologies if beneficial into NASA, and give feedback to the technology providers to improve the technologies. Each collaboration project produced a final report. Section 2 of this report summarizes each project, drawing from the final reports and communications with the software developers and technology providers. Section 3 indicates paths to further infusion of the technologies into NASA practice. Section 4 summarizes some technology transfer lessons learned. Also included is an acronym list.

Earthquake-induced Landslidingand Ground Damage In New Zealand  

NASA Astrophysics Data System (ADS)

A study of landsliding caused by 22 historical earthquakes in New Zealand was completed at the end of 1997 (Hancox et al., 1997). The main aims of that study were to determine: (a) the nature and extent of landsliding and other ground damage (sand boils, subsidence and lateral spreading due to soil liquefaction) caused by historical earthquakes; (b) relationships between landsliding and earthquake magnitude, epicentre, faulting, geology and topography; (c) improved environmental criteria and ground classes for assigning MM intensities and seismic hazard assessments in N.Z. The data and results of the 1997 study have recently been summarised and expanded (Hancox et al., in press), and are described in this paper. Relationships developed from these studies indicate that the minimum magnitude for earthquake-induced landsliding (EIL) in N.Z. is about M 5, with significant landsliding occurring at M 6 or greater. The minimum MM intensity for landsliding is MM6, while the most common intensities for significant landsliding are MM7-8. The intensity threshold for soil liquefaction in New Zealand was found to be MM7 for sand boils, and MM8 for lateral spreading, although such effects may also occur at one intensity level lower in highly susceptible materials. The minimum magnitude for liquefaction phenomena in N.Z. is about M 6, compared to M 5 overseas where highly susceptible soils are probably more widespread. Revised environmental response criteria (landsliding, subsidence, liquefaction-induced sand boils and lateral spreading) have also been established for the New Zealand MM Intensity Scale, and provisional landslide susceptibility Ground Classes developed for assigning MM intensities in areas where there are few buildings. Other new data presented include a size/frequency distribution model for earthquake-induced landslides over the last 150 years and a preliminary EIL Opportunity model for N.Z. The application of EIL data and relationships for seismic hazard assessments in N.Z. is discussed, and suggestions are made for future EIL research, including detailed studies of important historical earthquakes, and groups of coeval prehistoric landslides that can be attributed to earthquakes.

Predicting Earthquakes  

NSDL National Science Digital Library

Five moderate-to-strong earthquakes struck California in June 2005. Could the cluster of quakes be a harbinger of the Big One? Another earthquake-prone area, New Madrid, near Memphis, Tennessee, has had more than its share of impressive quakes and strain is building along its fault lines. This radio broadcast discusses these two seismic zones, the new data based on years of GPS (Global Positioning System) measurements that may give scientists more information, and how the Earth generates the stress which leads to earthquakes. There is also discussion of the danger of tsunamis in the Virgin Islands and the need for a worldwide tsunami warning network. The broadcast is 18 minutes in length.

Earthquake Machine  

NSDL National Science Digital Library

This is a demonstration of the principle of elastic rebound for the cause and recurrence of earthquakes. Under the Elastic Rebound Theory, the continuous motion of plates on Earth causes stress to build up at the boundaries between the plates, where friction keeps the boundaries locked. Stress is continually building up, and earthquakes act to relieve that stress. In the demonstration, the two sides of a fault are represented by sandpaper-covered blocks resting on a sandpaper-covered board. A weight rests on the block to apply a chosen amount of pressure on the sandpaper (defining the frictional strength of the fault). A spring is attached to the block and to a string, on which a constant pull is maintained. This apparatus is used to discover when the stress causes the blocks to move. Conclusions on earthquake recurrence (seismicity) may then be drawn.

Modeling, Forecasting and Mitigating Extreme Earthquakes  

NASA Astrophysics Data System (ADS)

Recent earthquake disasters highlighted the importance of multi- and trans-disciplinary studies of earthquake risk. A major component of earthquake disaster risk analysis is hazards research, which should cover not only a traditional assessment of ground shaking, but also studies of geodetic, paleoseismic, geomagnetic, hydrological, deep drilling and other geophysical and geological observations together with comprehensive modeling of earthquakes and forecasting extreme events. Extreme earthquakes (large magnitude and rare events) are manifestations of complex behavior of the lithosphere structured as a hierarchical system of blocks of different sizes. Understanding of physics and dynamics of the extreme events comes from observations, measurements and modeling. A quantitative approach to simulate earthquakes in models of fault dynamics will be presented. The models reproduce basic features of the observed seismicity (e.g., the frequency-magnitude relationship, clustering of earthquakes, occurrence of extreme seismic events). They provide a link between geodynamic processes and seismicity, allow studying extreme events, influence of fault network properties on seismic patterns and seismic cycles, and assist, in a broader sense, in earthquake forecast modeling. Some aspects of predictability of large earthquakes (how well can large earthquakes be predicted today?) will be also discussed along with possibilities in mitigation of earthquake disasters (e.g., on 'inverse' forensic investigations of earthquake disasters).
