    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.

  16. The Challenge of Centennial Earthquakes to Improve Modern Earthquake Engineering

    SciTech Connect

    Saragoni, G. Rodolfo [Department of Civil Engineering, Universidad of Chile (Chile)

    2008-07-08

    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.

  17. Soil dynamics in earthquake engineering

    SciTech Connect

    Stewart, H.E.

    1987-01-01

    Collapsed buildings, buckled bridges, and other evidence of structural damage are what the news media usually focus on when reporting earthquakes. The impression may be that the responses of timber, steel, stone, and concrete are the only considerations in earthquake analysis and earthquake-resistant design. Actually, earth materials are a major factor. All constructed facilities are in some way founded on or in earth materials, and sometimes the structures - such as rock- and earth-fill dams - are constructed entirely of these materials. Since the soil is always present, it is difficult to separate earthquake damage, or prevention of damage, into components that are related entirely to a steel or concrete structure, or entirely to the supporting foundation materials. The study of how soil and rock behave as engineering materials is known as geotechnical engineering.

  7. A Prospect of Earthquake Prediction Research

    E-print Network

    Ogata, Yosihiko

    2013-01-01

    Earthquakes occur because of abrupt slips on faults due to accumulated stress in the Earth's crust. Because most of these faults and their mechanisms are not readily apparent, deterministic earthquake prediction is difficult. For effective prediction, complex conditions and uncertain elements must be considered, which necessitates stochastic prediction. In particular, a large amount of uncertainty lies in identifying whether abnormal phenomena are precursors to large earthquakes, as well as in assigning urgency to the earthquake. Any discovery of potentially useful information for earthquake prediction is incomplete unless quantitative modeling of risk is considered. Therefore, this manuscript describes the prospect of earthquake predictability research to realize practical operational forecasting in the near future.

The question what is needed for a meaningful earthquake prediction as well as what types of precursory effects can be expected is shortly discussed. The basic ideas of the dilatancy theory are presented which in principle can explain the occurrence of earthquake forerunners. The reasons for radon anomalies in soil gas and in ground water are clarified and a possible classification of radon anomalies is given. PMID:21669940

    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.

    When an earthquake occurs, seismologists want to use recorded seismograms to infer its location, magnitude and source-focal mechanism as quickly as possible. If such information could be determined immediately, timely evacuations and emergency actions could be undertaken to mitigate earthquake damage. Current advanced methods can report the initial location and magnitude of an earthquake within a few seconds, but estimating the source-focal mechanism may require minutes to hours. Here we present an earthquake search engine, similar to a web search engine, that we developed by applying a computer fast search method to a large seismogram database to find waveforms that best fit the input data. Our method is several thousand times faster than an exact search. For an Mw 5.9 earthquake on 8 March 2012 in Xinjiang, China, the search engine can infer the earthquakes parameters in <1?s after receiving the long-period surface wave data.

    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.

    2012-10-01

    The paper addresses the issue of researching into the engineering characteristics of rotational strong ground motion components and rotational effects in structural response. In this regard, at first, the acceleration response spectra of rotational components are estimated in terms of translational ones. Next, new methods in order to consider the effects of rotational components in seismic design codes are presented by determining the effective structural parameters in the rotational loading of structures due only to the earthquake rotational components. Numerical results show that according to the frequency content of rotational components, the contribution of the rocking components to the seismic excitation of short period structures can never be ignored. During strong earthquakes, these rotational motions may lead to the unexpected overturning or local structural damages for the low-rise multi-story buildings located on soft soil. The arrangement of lateral-load resisting system in the plan, period, and aspect ratio of the system can severely change the seismic loading of wide symmetric buildings under the earthquake torsional component.

    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.

    Interns in the program Southern California Earthquake Center/Undergraduate Studies in Earthquake Information Technology (SCEC/UseIT, an NSF Research Experience for Undergraduates Site) have designed, engineered, and distributed SCEC-VDO (Virtual Display of Objects), an interactive software used by earthquake scientists and educators to integrate and visualize global and regional, georeferenced datasets. 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.

    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.

    Reliable, repeatable earthquake forecast is a subject surrounded by controversy and scepticism. What is clear is that reliable forecast would be a critical tool for effective earthquake disaster management. It is proposed that satellites and ground-based facilities may detect earthquake precursors in the ionosphere a few hours or days before the main shock. A low-cost 100 kg class satellite carrying a topside sounder is proposed, to make systematic measurements over seismically active zones. The mission aims to confirm or refute the hypothesis of ionospheric earthquake precursors, define the reliability and reproducibility, and enable further scientific understanding of their mechanisms.

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

    2014-08-01

    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.

    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.

    Strong motion records are the original input data for earthquake engineering studies and earthquake resistant building codes. Records originating from both, analogue and modern digital instruments should be subjected to processing in order to derive credible engineering parameters, such as spectral ordinates. A number of processing procedures have been proposed by many researchers through the past few decades; the goal, however, is always the same, identification and removal of noise and performing necessary adjustments related to the operating instrument or the record's quality. A careful inspection of previous processing schemes and the design of several development tests related to major processing steps proved to be helpful in determining the necessary features that the presented software should include. These have been incorporated in a Matlab application in order to produce a reliable and user-friendly interface giving the researcher several options on major processing steps. It is noteworthy that this computer program can be used either as an interactive process tool when individual record processing corresponds to the researcher's needs or, for processing a vast number of records without user supervision and even through a scheduled task.

    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.)

    Landslides are a common ground effect induced by earthquakes of moderate to large magnitude. Most of them correspond to first-time instabilities induced by the seismic event, being the reactivation of pre-existing landslides less frequent in practice. The landslide of Gevejar (Granada province, S Spain) represents a case study of landslide that was reactivated, at least, two times by far field earthquakes: the Mw 8.7, 1755, Lisbon earthquake (with estimated epicentral distance of 680 km), and the Mw 6.5, 1884, Andalucia event (estimated epicentral distance of 45 km), but not by near field events of moderate magnitude (Mw < 6.0 and epicentral distances lower than 25 km). To study the seismic response of this landslide, a study has been conducted to elaborate an engineering-geological model. For this purpose, field work done included the elaboration of a detailed geological map (1:1000) of the landslide and surrounding areas, drilling of deep boreholes (80 m deep), down-hole measurement of both P and S wave velocities in the boreholes drilled, piezometric control of water table, MASW and ReMi profiles for determining the underlying structure of the sites tested (soil profile stratigraphy and the corresponding S-wave velocity of each soil level) and undisturbed sampling of the materials affected by the landslide. These samples were then tested in laboratory according to standard procedures for determination of both static (among which soil density, soil classification and shear strength) and dynamic properties (degradation curves for shear modulus and damping ratio with shear strain) of the landslide-involved materials. The model proposed corresponds to a complex landslide that combines a rototranslational mechanism with an earth-flow at its toe, which is characterized by a deep (> 50 m) sliding surface. The engineering-geological model constitutes the first step in an ongoing research devoted to understand how it could be reactivated during far field events.

    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.

    Researches on Nankai trough mega trust earthquakes around south western Japan are very important for Earthquake/Tsunami disaster mitigation in Japan. Especially, the offshore real time monitoring systems are indispensable for the early warning of earthquakes and tsunamis. Actually, lessons from 2004 Sumatra Earthquake/Tsunami and 2011 East Japan Earthquake accelerate deployments of ocean floor networks such as DONET1, DONET2 around the Nankai trough and Inline cable systems off East Japan. Already, DONET1 have deployed on the Tonankai earthquake seismogenic zone, and DONET2 on the Nankai earthquake seismogenic zone is under developing. In the Nankai trough seismogenic zones, mega thrust earthquakes have occurred with the intervals of every 100-200 years. However, recurrence patters among these mega thrust earthquakes in 1944/ 1946, 1854, 177 and 1605 are quite different. Furthermore, these seismogenic zones are located near the coasts of southwestern Japan, tsunami will come very fast, so evacuations from tsunamis are severe problems at coastal cities southwestern Japan. Based on these conditions, Japanese government and research community recognized that real time monitoring systems of earthquakes and tsunamis are very important for EEW and prediction researches. Furthermore, the Ocean floor network equipped with multi kinds of sensors such as seismometers and pressure gauges are very powerful and significant tool to monitor the broad band phenomena in seismogenic zones. In the Nankai trough, we constructed DONET1 which is Dense Ocean floor Network for Earthquakes and Tsunamis around the Tonankai seismogenic zone with 20 observatories. Multi kinds of sensors such as an accelerometer, a broad band seismometer, a precise pressure gauge, a differential pressure gauge and a precise thermometer are equipped in each observatory. Now, we are already developing DONET2 with 31observatories around the Nankai seismogenic zone. Furthermore, advanced earthquake/tsunami simulations for scenario researches, hazard evaluations and evacuations are very important and significant. Finally, we will apply these real time data and advanced simulations to early warning researches, prediction researches, hazard evaluation researches for the Earthquake/Tsunami disaster mitigations and understandings of seismic linkages among mega thrust earthquakes around the Nankai trough.

    Taiwan has been known as an excellent natural laboratory characterized by rapid active tectonic rate and high dense seismicity. The Eastern Taiwan Earthquake Research Center (E-TEC) is established on 2013/09/24 in National Dong Hwa University and collaborates with Central Weather Bureau (CWB), National Center for Research on Earthquake Engineering (NCREE), National Science and Technology Center for Disaster Reduction (NCDR), Institute of Earth Science of Academia Sinica (IES, AS) and other institutions (NCU, NTU, CCU) and aims to provide an integrated platform for researchers to conduct the new advances on earthquake precursors and early warning for seismic disaster prevention in the eastern Taiwan, as frequent temblors are most common in the East Taiwan rift valley. E-TEC intends to integrate the multi-disciplinary observations and is equipped with stations to monitor a wide array of factors of quake precursors, including seismicity, GPS, strain-meter, ground water, geochemistry, gravity, electromagnetic, ionospheric density, thermal infrared remote sensing, gamma radiation etc, and will maximize the value of the data for researches with the range of monitoring equipment that enable to predict where and when the next devastated earthquake will strike Taiwan and develop reliable earthquake prediction models. A preliminary study on earthquake precursor using monthly Moderate Resolution Imaging Spectroradiometer (MODIS) Land Surface Temperature (LST) data before 2013/03/27 Mw6.2 Nantou earthquake in Taiwan is presented. Using the statistical analysis, the result shows the peak of the anomalous LST that exceeds a standard deviation of LST appeared on 2013/03/09 and became less or none anomalies observed on 2013/03/16 before the main-shock, which is in consist with the phenomenon observed by other researchers. This preliminary experimental result shows that the thermal anomalies reveal the possibility to associate surface thermal phenomena before the strong earthquakes.

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

    USGS Publications Warehouse

    Obermeier, Stephen F.

    1989-01-01

    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.

    NASA Astrophysics Data System (ADS)

    Mavroeidis, George P.

    This dissertation aims at providing to earthquake engineers simple tools and techniques that enhance the physical understanding, characterization, proper parameterization, analytical modeling, and numerical simulation of near-fault ground motions for earthquake engineering applications. A simple analytical model is proposed for the representation of near-source ground motions that adequately describes the impulsive character of near-fault seismic excitations both qualitatively and quantitatively. In addition, it can be used to analytically reproduce empirical observations that are based on available near-source records. The model input parameters have an unambiguous physical interpretation and scale, to the extent possible, with physical parameters of the fault rupture. A simplified methodology, for generating realistic broadband near-fault ground motions that are adequate for engineering analysis and design, is outlined and applied. A comprehensive study of the elastic and inelastic response of the single-degree-of-freedom (SDOF) system subjected to near-fault ground motion excitations is also presented. As a key parameter of the ground motion model emerges the pulse duration that is used to normalize the abscissa (period-axis) of response spectra. Such normalization makes feasible the specification of design spectra and reduction factors appropriate for near-fault ground motions. The effect of fault rupture characteristics on near-fault ground motions is also investigated using a kinematic approach in an attempt to identify physical processes that lead to specific ground motion patterns. Finally, the primary characteristics of strain, rocking, and torsional components of ground motion in the near-fault region induced by seismic excitations are discussed and a simplified approach is presented for the qualitative and quantitative description of the torsional component of the dynamic ground deformation field.

    "If I were a brilliant scientist, I would be working on earthquake prediction." This is a statement from a Los Angeles radio talk show I heard just after the Northridge earthquake of January 17, 1994. Five weeks later, at a monthly meeting of the Southern California Earthquake Center (SCEC), where more than two hundred scientists and engineers gathered to exchange notes on the earthquake, a distinguished French geologist who works on earthquake faults in China envied me for working now in southern California. This place is like northeastern China 20 years ago, when high seismicity and research activities led to the successful prediction of the Haicheng earthquake of February 4, 1975 with magnitude 7.3. A difficult question still haunting us [Aki, 1989] is whether the Haicheng prediction was founded on the physical reality of precursory phenomena or on the wishful thinking of observers subjected to the political pressure which encouraged precursor reporting. It is, however, true that a successful life-saving prediction like the Haicheng prediction can only be carried out by the coordinated efforts of decision makers and physical scientists.

    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.

    At 2:46 pm on March 11, 2011, a huge earthquake (M 9.0) occurred off the Pacific coast of Tohoku Region, Japan. The subsequent Tsunamis hit the coasts and seriously damaged fishing villages and towns in the area. Tohoku Region faces Northwestern Pacific where is one of the most productive oceans on the Earth. Then, what happened to the marine ecosystems in the Tohoku Region? What happened to the fishery bioresources? What is the mechanism to sustain high productivity in the Region? Is the ecosystem restoring after 4 years? What is required for the recovery of fisheries in the area? In order to answer these questions, the 10 years research project, TEAMS (Tohoku Ecosystem-Associated Marine Sciences) was launched in January 2012 funded by MEXT (Ministry of Education, Culture, Sports, Science and Technology, Japan) to conduct comprehensive research on the area. Tohoku University (TU), Atmosphere and Ocean Research Institute, the University of Tokyo (AORIUT), Japan Agency for Marine-Earth Science and Technology (JAMSTEC), and 25 other institutions are conducting research for this project in close association with local government and fishery people. Currently, approximately 400 people (200 scientists, 160 students and others) covering physical, chemical, biological, and geological sciences including modeling take part in the project from all over Japan. MEXT also supports TEAMS by constructing R/V Shinsei Maru in 2013 for the oceanic investigations in the region. In this report, the overview of the ecosystem before and after the disaster, major findings and challenges of TEAMS will be described.

    A catalog has been prepared which contains information for: (1) world-wide, ground-motion accelerograms, (2) the accelerograph sites where these records were obtained, and (3) the seismological parameters of the causative earthquakes. The catalog is limited to data for those accelerograms which have been digitized and published. In addition, the quality and completeness of these data are assessed. This catalog is unique because it is the only publication which contains comprehensive information on the recording conditions of all known digitized accelerograms. However, information for many accelerograms is missing. Although some literature may have been overlooked, most of the missing data has not been published. Nevertheless, the catalog provides a convenient reference and useful tool for earthquake engineering research and applications.

  1. The effects of earthquake measurement concepts and magnitude anchoring on individuals' perceptions of earthquake risk

    USGS Publications Warehouse

    Celsi, R.; Wolfinbarger, M.; Wald, D.

    2005-01-01

    The purpose of this research is to explore earthquake risk perceptions in California. Specifically, we examine the risk beliefs, feelings, and experiences of lay, professional, and expert individuals to explore how risk is perceived and how risk perceptions are formed relative to earthquakes. Our results indicate that individuals tend to perceptually underestimate the degree that earthquake (EQ) events may affect them. This occurs in large part because individuals' personal felt experience of EQ events are generally overestimated relative to experienced magnitudes. An important finding is that individuals engage in a process of "cognitive anchoring" of their felt EQ experience towards the reported earthquake magnitude size. The anchoring effect is moderated by the degree that individuals comprehend EQ magnitude measurement and EQ attenuation. Overall, the results of this research provide us with a deeper understanding of EQ risk perceptions, especially as they relate to individuals' understanding of EQ measurement and attenuation concepts. ?? 2005, Earthquake Engineering Research Institute.

  9. Charles Darwin's earthquake reports

    NASA Astrophysics Data System (ADS)

    Galiev, Shamil

    2010-05-01

    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.

    1991-01-01

    The Army Propulsion Directorate is primarily concerned with small engine technology, where sealing performance is most critical. Tip leakage and secondary flow losses have a much greater performance impact on small engine aero-components than on large engines. A brief survey and critique of presently employed sealing concepts is presented. Some recent new research thrusts that show promise for substantial improvement are discussed. An especially promising approach for small engine applications is brush seals. Brush seal concepts are being considered for outer air seal and secondary airflow system seal locations.

    2006-01-01

    The Niigata Ken Chuetsu earthquake triggered a vast number of lanslides in the epicentral region. Landslide concentrations were among the highest ever measured after an earthquake, and most of the triggered landslides were relatively shallow failures parallel to the steep slope faces. The dense concentration of landslides can be attributed to steep local topography in relatively weak geologic units, adverse hydrologic conditions caused by significant antecedent rainfall, and very strong shaking. Many of the landslides could be discerned from high-resolution satellite imagery acquired immediately after the earthquake. ?? 2006, Earthquake Engineering Research Institute.

    WEGENER was originally the acronym for Working Group of European Geoscientists for the Establishment of Networks for Earth-science Research. It was founded in March 1981 in response to an appeal delivered at the Journes Luxembourgeoises de Geodynamique in December 1980 to respond with a coordinated European proposal to a NASA Announcement of Opportunity inviting participation in the Crustal Dynamics and Earthquake Research Program. WEGENER, during the past 33 years, has always kept a close contact with the Agencies and Institutions responsible for the development and maintenance of the global space geodetic networks with the aim to make them aware of the scientific needs and outcomes of the project which might have an influence on the general science policy trends. WEGENER served as Inter-commission Project 3.2, between Commission 1 and Commission 3, of the International Association of Geodesy (IAG) until 2012. Since then, WEGENER project has become the Sub-commission 3.5 of IAG commission 3, namely Tectonics and Earthquake Geodesy. In this presentation, we briefly review the accomplishments of WEGENER as originally conceived and outline and justify the new focus of the WEGENER consortium. The remarkable and rapid evolution of the present state of global geodetic monitoring in regard to the precision of positioning capabilities (and hence deformation) and global coverage, the development of InSAR for monitoring strain with unprecedented spatial resolution, and continuing and planned data from highly precise satellite gravity and altimetry missions, encourage us to shift principal attention from mainly monitoring capabilities by a combination of space and terrestrial geodetic techniques to applying existing observational methodologies to the critical geophysical phenomena that threaten our planet and society. Our new focus includes developing an improved physical basis to mitigate earthquake, tsunami, and volcanic risks, and the effects of natural and anthropogenic climate change (sea level, ice degradation). In addition, expanded applications of space geodesy to atmospheric studies will remain a major focus with emphasis on ionospheric and tropospheric monitoring to support forecasting extreme events. Towards these ends, we will encourage and foster interdisciplinary, integrated initiatives to develop a range of case studies for these critical problems. Geological studies are needed to extend geodetic deformation studies to geologic time scales, and new modeling approaches will facilitate full exploitation of expanding geodetic databases. In light of this new focus, the WEGENER acronym now represents, 'World Earthquake GEodesy Network for Environmental Hazard Research.

    Over the past year, the Propulsion Engineering Research Center at The Pennsylvania State University continued its progress toward meeting the goals of NASA's University Space Engineering Research Centers (USERC) program. The USERC program was initiated in 1988 by the Office of Aeronautics and Space Technology to provide an invigorating force to drive technology advancements in the U.S. space industry. The Propulsion Center's role in this effort is to provide a fundamental basis from which the technology advances in propulsion can be derived. To fulfill this role, an integrated program was developed that focuses research efforts on key technical areas, provides students with a broad education in traditional propulsion-related science and engineering disciplines, and provides minority and other under-represented students with opportunities to take their first step toward professional careers in propulsion engineering. The program is made efficient by incorporating government propulsion laboratories and the U.S. propulsion industry into the program through extensive interactions and research involvement. The Center is comprised of faculty, professional staff, and graduate and undergraduate students working on a broad spectrum of research issues related to propulsion. The Center's research focus encompasses both current and advanced propulsion concepts for space transportation, with a research emphasis on liquid propellant rocket engines. The liquid rocket engine research includes programs in combustion and turbomachinery. Other space transportation modes that are being addressed include anti-matter, electric, nuclear, and solid propellant propulsion. Outside funding supports a significant fraction of Center research, with the major portion of the basic USERC grant being used for graduate student support and recruitment. The remainder of the USERC funds are used to support programs to increase minority student enrollment in engineering, to maintain Center infrastructure, and to develop research capability in key new areas. Significant research programs in propulsion systems for air and land transportation complement the space propulsion focus. The primary mission of the Center is student education. The student program emphasizes formal class work and research in classical engineering and science disciplines with applications to propulsion.

    This lecture will provide an overview of the aircraft turbine engine control research at NASA (National Aeronautics and Space Administration) Glenn Research Center (GRC). A brief introduction to the engine control problem is first provided with a description of the current state-of-the-art control law structure. A historical aspect of engine control development since the 1940s is then provided with a special emphasis on the contributions of GRC. The traditional engine control problem has been to provide a means to safely transition the engine from one steady-state operating point to another based on the pilot throttle inputs. With the increased emphasis on aircraft safety, enhanced performance and affordability, and the need to reduce the environmental impact of aircraft, there are many new challenges being faced by the designers of aircraft propulsion systems. The Controls and Dynamics Branch (CDB) at GRC is leading and participating in various projects in partnership with other organizations within GRC and across NASA, other government agencies, the U.S. aerospace industry, and academia to develop advanced propulsion controls and diagnostics technologies that will help meet the challenging goals of NASA programs under the Aeronautics Research Mission. The second part of the lecture provides an overview of the various CDB technology development activities in aircraft engine control and diagnostics, both current and some accomplished in the recent past. The motivation for each of the research efforts, the research approach, technical challenges and the key progress to date are summarized. The technologies to be discussed include system level engine control concepts, gas path diagnostics, active component control, and distributed engine control architecture. The lecture will end with a futuristic perspective of how the various current technology developments will lead to an Intelligent and Autonomous Propulsion System requiring none to very minimum pilot interface, interfacing directly with the flight management system to determine its mode of operation, and providing personalized engine control to optimize its performance given the current condition and mission objectives.

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

    NASA Astrophysics Data System (ADS)

    Cho, In Ho

    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.

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

    NASA Technical Reports Server (NTRS)

    Freymueller, Jeffrey T.

    1999-01-01

    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.

  20. Engineering geologic assessment of the slope movements and liquefaction failures of the 23 October 2011 Van earthquake (Mw= 7.2)

    NASA Astrophysics Data System (ADS)

    Karaka?, A.; Coruk, .; Do?an, B.

    2013-04-01

    On 23 October 2011, a Mw = 7.2 earthquake occurred in the Van Province in eastern Turkey, killing 604 people. The earthquake was triggered by a thrust fault due to a compression stress in the region, and caused extensive damage over a large area. Many structures in the earthquake region collapsed, and the damage spread from the city of Van to the town of Erci?, in a distance of 60 km. The earthquake generated several slope movements and liquefaction failures in the region, and this study evaluates these processes from the perspective of engineering geology, and presents field and laboratory results related to these processes. Attenuation relationships were used for estimation of peak ground accelerations (PGAs), and an empirical liquefaction evaluation method employing ground accelerations was used to define threshold accelerations initiating the liquefaction. The results demonstrate that landslides were widespread and more frequently observed in the field in comparison with earthflows and rockfalls. Flow-type liquefaction and lateral spreading was found to be widespread and more common than the liquefaction-related settlement. The minimum threshold acceleration value for the initiation of soil liquefaction was calculated to be 188.87 cm s-2 (~0.19 g) in the earthquake region. Laboratory results indicated that the soil liquefaction was closely associated with grain size. The slope instabilities, liquefaction and associated ground failures occurred mainly in rural areas, and their impact on structures was quite low as compared to the human loss and structural damage by the earthquake.

    Han, Zhu-Jun; Ren, Fu-Hu; Ogawa, Yujiro; Taniguchi, Hitoshi

    1996-11-01

    Based on the geological tectonics, aftershock activity, earthquake surface rupture and peak ground motion, the geometric and dynamic characteristics of seismogenic tectonics about the 1995 Hanshin earthquake are analysed. Nojima fault and Rokko fault have the same trending direction, but opposite dips. Their rising and falling plates are in symmetrically diagonal distribution. The two faults can be defined as thrust-strike slip faults and constitute a pivotal strike-slip fault. The earthquake just occurred at the pivot, which is the seismotectonics for the earthquake to develop and occur. The pivotal movement along a strike-slip fault often leads to the occurrence of large earthquakes, whose dynamic process can be demonstrated by the stress analysis on the torsion of a beam with rectangle section. The displacement of earthquake surface rupture, aftershock density and peak acceleration change in a certain range of epicentral distance just similar as the shear stress changes from the center to the sides in the rectangle section. The distribution characteristics of the heaviest damage areas are also discussed in the article from the aspects of special geological tectonics and seismotectonic condition. The result obtained from the article can be applied not only to realizing the potencial earthquake sources in middle-long time, but also to build reasonably the prediction model about earthquake hazard.

  5. Research Skills in a Mechanical Engineering Curriculum

    NSDL National Science Digital Library

    De Graaff, Erik

    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.

    This review briefly describes two other books on the same subject either written or partially written by Rikitake. In this book, the status of earthquake prediction efforts in Japan, China, the Soviet Union, and the United States are updated. An overview of some of the organizational, legal, and societal aspects of earthquake prediction in these countries is presented, and scientific findings of precursory phenomena are included. A summary of circumstances surrounding the 1975 Haicheng earthquake, the 1978 Tangshan earthquake, and the 1976 Songpan-Pingwu earthquake (all magnitudes = 7.0) in China and the 1978 Izu-Oshima earthquake in Japan is presented. This book fails to comprehensively summarize recent advances in earthquake prediction research.

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

    SciTech Connect

    Chung, D. H.; Bernreuter, D. L.

    1980-05-01

    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.

  10. Collaborative Engineering for Research and Development

    NASA Technical Reports Server (NTRS)

    Davis, Jose M.; Keys, L. Ken; Chen, Injazz J.

    2004-01-01

    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.

    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.

    We recognized the importance of real time monitoring on Earthquakes and Tsunamis Based on lessons learned from 2004 Sumatra Earthquake/Tsunamis and 2011 East Japan Earthquake. We deployed DONET1 and are developing DONET2 as real time monitoring systems which are dense ocean floor networks around the Nankai trough seismogenic zone Southwestern Japan. Total observatories of DONE1 and DONET2 are 51 observatories equipped with multi kinds of sensors such as the accelerometer, broadband seismometer, pressure gauge, difference pressure gauge, hydrophone and thermometer in each observatory. These systems are indispensable for not only early warning of Earthquakes/ Tsunamis, but also researches on broadband crustal activities around the Nankai trough seismogenic zone for predictions. DONET1 detected offshore tsunamis 15 minutes earlier than onshore stations at the 2011 East Japan earthquake/tsunami. Furthermore, DONET1/DONET2 will be expected to monitor slow events such as low frequency tremors and slow earthquakes for the prediction researches. Finally, the integration of observations and simulation researches will contribute to estimate of seismic stage changes from the inter-seismic to pre seismic stage. I will introduce applications of DONET1/DONET2 data and advanced simulation researches.

  11. Earthquake resistant design

    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.

    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.

    Laboratory based Dilatancy-diffusion model predicts that crustal rocks when subjected to various degrees of stresses, simulating different phases of earthquake preparatory cycle, undergo opening of minor cracks, in-flux of fluids, material strengthening prior to the rupture. These changes producing small perturbation in physical properties of rocks are manifested in the enhanced micro-seismicity, seismic wave velocity changes, crustal deformation, small-scale changes in gravity, resistivity, magnetic field intensity, electromagnetic and radon gas emission as well as by fluctuations in hydrological parameters. Recognising that simultaneous measurements of inter-disciplinary parameters are key to decipher characteristic space-time variation during the earthquake preparatory cycles, a Multi-Parameteric Geophysical Observatory (MPGO) has been established at Ghuttu, Central Himalaya. Located in a narrow belt of high seismicity, just south of the Main Central Thrust of the Himalaya, has been the seat of recent 1991-Uttarkashi and 1999-Chamoli earthquakes, both M> 6. The MPGO became fully operational in April 2007 and is equipped with super conducting gravimeter, overhauser magnetometer, tri-axial fluxgate magnetometer, ULF band search coil magnetometer, radon data logger, water level recorders and is backed up by the dense network of Broad Band Seismometers (BBS) and GPS. However, the isolation of weak earthquake precursory signal further requires characterization of time variability related to environmental, hydrological, tectonic and even inter planetary processes affecting differently each geophysical time series. Demonstrating the potential of data adoptive techniques like Principal Component Analysis, Wavelet, Singular Spectrum Analysis, Fractal etc in denoising and allowing parameterization of tidal, pressure and hydrological influence on gravity and other time series, the presentation shall present nature of precursory signals in gravity, magnetic, radon and water level in association with a moderate 4.9 M Kharsali Earthquake of July 22, 2007, largest local earthquake recorded since the MPGO became functional.

    The mission of the Engineering Research, Development, and Technology Program at Lawrence Livermore National Laboratory (LLNL) is to develop the knowledge base, process technologies, specialized equipment, tools and facilities to support current and future LLNL programs. Engineering`s efforts are guided by a strategy that results in dual benefit: first, in support of Department of Energy missions, such as national security through nuclear deterrence; and second, in enhancing the nation`s economic competitiveness through their collaboration with US industry in pursuit of the most cost-effective engineering solutions to LLNL programs. To accomplish this mission, the Engineering Research, Development, and Technology Program has two important goals: (1) identify key technologies relevant to LLNL programs where they can establish unique competencies, and (2) conduct high-quality research and development to enhance their capabilities and establish themselves as the world leaders in these technologies. To focus Engineering`s efforts, technology thrust areas are identified and technical leaders are selected for each area. The thrust areas are comprised of integrated engineering activities, staffed by personnel from the nine electronics and mechanical engineering divisions, and from other LLNL organizations. This annual report, organized by thrust area, describes Engineering`s activities for fiscal year 1995. The report provides timely summaries of objectives methods, and key results from eight thrust areas: computational electronics and electromagnetics; computational mechanics; microtechnology; manufacturing technology; materials science and engineering; power conversion technologies; nondestructive evaluation; and information engineering.

  11. Discrimination between NTS explosions, earthquakes and the non-proliferation experiment at the Pinedale Seismic Research Facility

    SciTech Connect

    Carr, D.

    1994-09-01

    As the United States moves into an atmosphere of concern about the spread of nuclear weapons to non-nuclear countries, the focus on monitoring nuclear explosions is changing from looking at specific test sites and yields to looking for tests of large and small yields from anywhere in the world. Discrimination of small events then becomes important and regional seismic monitoring the best method to detect and identify suspicious events. At the Pinedale Seismic Research Facility (PSRF) in Wyoming we have the opportunity to try different regional discriminants with nuclear tests from NTS, western US (W-US) earthquakes and the Non-Proliferation Experiment (NPE). Four discriminants that gave the best results in a study by Taylor et al. were tried: m{sub b}:M{sub s}, M{sub b}:M{sub s}{sup h}, log(L{sub g}/P{sub g}) and spectral ratios. The different discriminants were applied to the data (14 NTS explosions, the NPE, one Department of Defense (DOB) explosion and 34 NWS earthquakes) regardless of signal-to-noise. When the NTS explosions and NPE were only compared to four earthquakes located on or near the Test Site, all the discriminants except log(L{sub g}/P{sub g}) worked fairly well at PSRF. When the other WUS earthquakes and DOD explosion are included, only m{sub b}:M{sub s} shows any promise. Because of frequent physical variations in the earth`s crust, regional signals are complex and easily influenced by site and path characteristics. Looking at events from one specific area reduces the effects of the path, which is why three discriminants work well when the data set is restricted to events on or near NTS. The only discriminant not adversely affected from variations in path is m{sub b}:M{sub s}. This is probably because it is believed that source dimension, source time function and/or source mechanism is the cause for the differences between earthquakes and explosions with this discriminant, rather than any path effects.

  15. Overview of Engine Combustion Research at Sandia National Laboratories

    SciTech Connect

    Robert W. Carling; Gurpreet Singh

    1999-04-26

    The objectives of this paper are to describe the ongoing projects in diesel engine combustion research at Sandia National Laboratories' Combustion Research Facility and to detail recent experimental results. The approach we are employing is to assemble experimental hardware that mimic realistic engine geometries while enabling optical access. For example, we are using multi-cylinder engine heads or one-cylinder versions of production heads mated to one-cylinder engine blocks. Optical access is then obtained through a periscope in an exhaust valve, quartz windows in the piston crown, windows in spacer plates just below the head, or quartz cylinder liners. We have three diesel engine experiments supported by the Department of Energy, Office of Heavy Vehicle Technologies: a one-cylinder version of a Cummins heavy-duty engine, a diesel simulation facility, and a one-cylinder Caterpillar engine to evaluate combustion of alternative diesel fuels.

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

    NASA Astrophysics Data System (ADS)

    Roeloffs, E. A.; Beeler, N. M.

    2013-12-01

    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.

  20. Estimating surface faulting impacts from the shakeout scenario earthquake

    USGS Publications Warehouse

    Treiman, J.A.; Pontib, D.J.

    2011-01-01

    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.

  1. 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.

  2. Demand surge following earthquakes

    USGS Publications Warehouse

    Olsen, Anna H.

    2012-01-01

    Demand surge is understood to be a socio-economic phenomenon where repair costs for the same damage are higher after large- versus small-scale natural disasters. It has reportedly increased monetary losses by 20 to 50%. In previous work, a model for the increased costs of reconstruction labor and materials was developed for hurricanes in the Southeast United States. The model showed that labor cost increases, rather than the material component, drove the total repair cost increases, and this finding could be extended to earthquakes. A study of past large-scale disasters suggested that there may be additional explanations for demand surge. Two such explanations specific to earthquakes are the exclusion of insurance coverage for earthquake damage and possible concurrent causation of damage from an earthquake followed by fire or tsunami. Additional research into these aspects might provide a better explanation for increased monetary losses after large- vs. small-scale earthquakes.

  3. On numerical earthquake prediction

    NASA Astrophysics Data System (ADS)

    Shi, Yaolin; Zhang, Bei; Zhang, Siqi; Zhang, Huai

    2014-06-01

    Can earthquakes be predicted? How should people overcome the difficulties encountered in the study of earthquake prediction? This issue can take inspiration from the experiences of weather forecast. Although weather forecasting took a period of about half a century to advance from empirical to numerical forecast, it has achieved significant success. A consensus has been reached among the Chinese seismological community that earthquake prediction must also develop from empirical forecasting to physical prediction. However, it is seldom mentioned that physical prediction is characterized by quantitatively numerical predictions based on physical laws. This article discusses five key components for numerical earthquake prediction and their current status. We conclude that numerical earthquake prediction should now be put on the planning agenda and its roadmap designed, seismic stations should be deployed and observations made according to the needs of numerical prediction, and theoretical research should be carried out.

    These researches present a solution for reducing the fatigue of the Diesel engine by permitting the preservation of its components and, at the same time, raising its specific horsepower to a par with that of carburetor engines, while maintaining for the Diesel engine its perogative of burning heavy fuel under optimum economical conditions. The feeding of Diesel engines by injection pumps actuated by engine compression achieves the required high speeds of injection readily and permits rigorous control of the combustible charge introduced into each cylinder and of the peak pressure in the resultant cycle.

  13. Response of a 14-story Anchorage, Alaska, building in 2002 to two close earthquakes and two distant Denali fault earthquakes

    USGS Publications Warehouse

    Celebi, M.

    2004-01-01

    The recorded responses of an Anchorage, Alaska, building during four significant earthquakes that occurred in 2002 are studied. Two earthquakes, including the 3 November 2002 M7.9 Denali fault earthquake, with epicenters approximately 275 km from the building, generated long trains of long-period (>1 s) surface waves. The other two smaller earthquakes occurred at subcrustal depths practically beneath Anchorage and produced higher frequency motions. These two pairs of earthquakes have different impacts on the response of the building. Higher modes are more pronounced in the building response during the smaller nearby events. The building responses indicate that the close-coupling of translational and torsional modes causes a significant beating effect. It is also possible that there is some resonance occurring due to the site frequency being close to the structural frequency. Identification of dynamic characteristics and behavior of buildings can provide important lessons for future earthquake-resistant designs and retrofit of existing buildings. ?? 2004, Earthquake Engineering Research Institute.

    A simple model of earthquake triggering and rupture propagation, based on concepts of earthquake mechanism commonly accepted, suggests that earthquake prediction (especially prediction of magnitude) might be very difficult, depending on the values of certain stress parameters. The concepts in the model suggest lines of research which may help to judge how successful the earthquake prediction effort might eventually be.

    1981-01-01

    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.

    NACA research on afterburners for turbojet engines during the past 5 years is summarized. Although most of this work has been directed toward the development of specific afterburners for various engines rather than toward the accumulation of systematic data, it has, nevertheless, provided a large fund of experimental data and experience in the field. The references cited present over 1000 afterburner configurations and some 3500 hours of operation. In the treatment of the material of this summary, the principal effort has been to convey to the reader the "know-how" acquired by research engineers in the course of the work rather than to formulate a set of design rules.

    2007-12-01

    As part of the preparations for the future earthquake in Istanbul a Rapid Response and Early Warning system in the metropolitan area is in operation. For the Early Warning system ten strong motion stations were installed as close as possible to the fault zone. Continuous on-line data from these stations via digital radio modem provide early warning for potentially disastrous earthquakes. Considering the complexity of fault rupture and the short fault distances involved, a simple and robust Early Warning algorithm, based on the exceedance of specified threshold time domain amplitude levels is implemented. The band-pass filtered accelerations and the cumulative absolute velocity (CAV) are compared with specified threshold levels. When any acceleration or CAV (on any channel) in a given station exceeds specific threshold values it is considered a vote. Whenever we have 2 station votes within selectable time interval, after the first vote, the first alarm is declared. In order to specify the appropriate threshold levels a data set of near field strong ground motions records form Turkey and the world has been analyzed. Correlations among these thresholds in terms of the epicenter distance the magnitude of the earthquake have been studied. The encrypted early warning signals will be communicated to the respective end users. Depending on the location of the earthquake (initiation of fault rupture) and the recipient facility the alarm time can be as high as about 8s. The first users of the early warning signal will be the Istanbul gas company (IGDAS) and the metro line using the immersed tube tunnel (MARMARAY). Other prospective users are power plants and power distribution systems, nuclear research facilities, critical chemical factories, petroleum facilities and high-rise buildings. In this study, different algorithms based on PGA, CAV and various definitions of instrumental intensity will be discussed and triggering threshold levels of these parameters will be studied. More complex algorithms based on artificial neural networks (ANN) can also be used [Boese et al., 2003]. ANN approach considers the problem of earthquake early-warning as a pattern recognition task. The seismic patterns can be defined by the shape and frequency content of the parts of accelerograms that are available at each time step. ANN can extract the engineering parameters PGA, CAV and instrumental intensity from these patterns, and map them to any location in the surrounded area. Boese M., Erdik, M., Wenzel, F.

    2006-12-01

    The most effective means of communicating science to today's "high-tech" students is through the use of visually attractive and animated lessons, hands-on activities, and interactive Internet-based exercises. To address these needs, we have developed Earthquakes in Action, a summer high school enrichment course offered through the California State Summer School for Mathematics and Science (COSMOS) Program at the University of California, San Diego. The summer course consists of classroom lectures, lab experiments, and a final research project designed to foster geophysical innovations, technological inquiries, and effective scientific communication (http://topex.ucsd.edu/cosmos/earthquakes). Course content includes lessons on plate tectonics, seismic wave behavior, seismometer construction, fault characteristics, California seismicity, global seismic hazards, earthquake stress triggering, tsunami generation, and geodetic measurements of the Earth's crust. Students are introduced to these topics through lectures-made-fun using a range of multimedia, including computer animations, videos, and interactive 3-D visualizations. These lessons are further enforced through both hands-on lab experiments and computer-based exercises. Lab experiments included building hand-held seismometers, simulating the frictional behavior of faults using bricks and sandpaper, simulating tsunami generation in a mini-wave pool, and using the Internet to collect global earthquake data on a daily basis and map earthquake locations using a large classroom map. Students also use Internet resources like Google Earth and UNAVCO/EarthScope's Jules Verne Voyager Jr. interactive mapping tool to study Earth Science on a global scale. All computer-based exercises and experiments developed for Earthquakes in Action have been distributed to teachers participating in the 2006 Earthquake Education Workshop, hosted by the Visualization Center at Scripps Institution of Oceanography (http://siovizcenter.ucsd.edu/workshop). In addition to daily lecture and lab exercises, COSMOS students also conduct a mini-research project of their choice that uses data ranging from the 2004 Parkfield Earthquake, to Southern California seismicity, to global seismicity. Students collect seismic data from the Internet and evaluate earthquake locations, magnitudes, temporal sequence of seismic activity, active fault planes, and plate tectonic boundaries using research quality techniques. Students are given the opportunity to build 3-D visualizations of their research data sets and archive these at the SIO Visualization Center's online library, which is globally accessible to students, teachers, researchers, and the general public (http://www.siovizcenter.ucsd.edu/library.php). These student- generated visualizations have become a practical resource for not only students and teachers, but also geophysical researchers that use the visual objects as research tools to better explore and understand their data. Through Earthquakes in Action, we offer both the tools for scientific exploration and the thrills of scientific discovery, providing students with valuable knowledge, novel research experience, and a unique sense of scientific contribution.

    2008-12-01

    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.

    An update is presented of non-turbine general aviation engine programs underway at the NASA-Lewis Research Center in Cleveland, Ohio. The program encompasses conventional, lightweight diesel and rotary engines. Its three major thrusts are: (a) reduced SFC's; (b) improved fuels tolerance; and (c) reducing emissions. Current and planned future programs in such areas as lean operation, improved fuel management, advanced cooling techniques and advanced engine concepts, are described. These are expected to lay the technology base, by the mid to late 1980's, for engines whose life cycle fuel costs are 30 to 50% lower than today's conventional engines.

  7. Initiatives to Reduce Earthquake Risk of Developing Countries

    The seventeen-year-and-counting history of the Palo Alto-based nonprofit organization GeoHazards International (GHI) is the story of many initiatives within a larger initiative to increase the societal impact of geophysics and civil engineering. GHI's mission is to reduce death and suffering due to earthquakes and other natural hazards in the world's most vulnerable communities through preparedness, mitigation and advocacy. GHI works by raising awareness in these communities about their risk and about affordable methods to manage it, identifying and strengthening institutions in these communities to manage their risk, and advocating improvement in natural disaster management. Some of GHI's successful initiatives include: (1) creating an earthquake scenario for Quito, Ecuador that describes in lay terms the consequences for that city of a probable earthquake; (2) improving the curricula of Pakistani university courses about seismic retrofitting; (3) training employees of the Public Works Department of Delhi, India on assessing the seismic vulnerability of critical facilities such as a school, a hospital, a police headquarters, and city hall; (4) assessing the vulnerability of the Library of Tibetan Works and Archives in Dharamsala, India; (5) developing a seismic hazard reduction plan for a nonprofit organization in Kathmandu, Nepal that works to manage Nepal's seismic risk; and (6) assisting in the formulation of a resolution by the Council of the Organization for Economic Cooperation and Development (OECD) to promote school earthquake safety among OECD member countries. GHI's most important resource, in addition to its staff and Board of Trustees, is its members and volunteer advisors, who include some of the world's leading earth scientists, earthquake engineers, urban planners and architects, from the academic, public, private and nonprofit sectors. GHI is planning several exciting initiatives in the near future. One would oversee the design and construction of an earthquake- and tsunami-resistant structure in Sumatra to house a tsunami museum, a community training center, and offices of a local NGO that is preparing Padang for the next tsunami. This facility would be designed and built by a team of US and Indonesian academics, architects, engineers and students. Another initiative would launch a collaborative research program on school earthquake safety with the scientists and engineers from the US and the ten Islamic countries that comprise the Economic Cooperation Organization. Finally, GHI hopes to develop internet and satellite communication techniques that will allow earthquake risk managers in the US to interact with masons, government officials, engineers and architects in remote communities of vulnerable developing countries, closing the science and engineering divide.

    Gregorek, G. M.; Reuss, R. L.

    1990-01-01

    Four student design teams produced conceptual designs for a research vehicle to develop the supersonic combustion ramjet (scramjet) engines necessary for efficient hypersonic flight. This research aircraft would provide flight test data for prototype scramjets that is not available in groundbased test facilities. The design specifications call for a research aircraft to be launched from a carrier aircraft at 40,000 feet and a Mach number of 0.8. The aircraft must accelerate to Mach 6 while climbing to a 100,000 foot altitude and then ignite the experimental scramjet engines for acceleration to Mach 10. The research vehicle must then be recovered for another flight. The students responded with four different designs, two piloted waverider configurations, and two unmanned vehicles, one with a blended body-wing configuration, the other with a delta wing shape. All aircraft made use of an engine database provided by the General Electric Aircraft Engine Group; both turbofan ramjet and scramjet engine performance using liquid hydrogen fuel was available. Explained here are the students' conceptual designs and the aerodynamic and propulsion concepts that made their designs feasible.

  5. Characterizing Interdisciplinarity of Researchers and Research Topics Using Web Search Engines

    2012-01-01

    Researchers' networks have been subject to active modeling and analysis. Earlier literature mostly focused on citation or co-authorship networks reconstructed from annotated scientific publication databases, which have several limitations. Recently, general-purpose web search engines have also been utilized to collect information about social networks. Here we reconstructed, using web search engines, a network representing the relatedness of researchers to their peers as well as to various research topics. Relatedness between researchers and research topics was characterized by visibility boostincrease of a researcher's visibility by focusing on a particular topic. It was observed that researchers who had high visibility boosts by the same research topic tended to be close to each other in their network. We calculated correlations between visibility boosts by research topics and researchers' interdisciplinarity at the individual level (diversity of topics related to the researcher) and at the social level (his/her centrality in the researchers' network). We found that visibility boosts by certain research topics were positively correlated with researchers' individual-level interdisciplinarity despite their negative correlations with the general popularity of researchers. It was also found that visibility boosts by network-related topics had positive correlations with researchers' social-level interdisciplinarity. Research topics' correlations with researchers' individual- and social-level interdisciplinarities were found to be nearly independent from each other. These findings suggest that the notion of interdisciplinarity" of a researcher should be understood as a multi-dimensional concept that should be evaluated using multiple assessment means.

    Khoo, Michel

    In 2003, the National Science Foundation awarded a large private urban research university funds to create an Engineering Research Center (ERC)- a center dedicated to the coordination of groundbreaking research in the development of biomimetic devices. The ERC brings physicians, biologists, engineers and educators together to develop microelectronic systems that interact with living, human tissues. The resulting technology enables implantable and portable devices that can treat presently incurable diseases such as blindness, loss of neuromuscular control, paralysis, and the loss of cognitive function. The researchers focus on mixed signal systems on chip, power and data management, intelligent analog circuits, interface technology at the nano- and microscales to integrate microelectronic systems with neurons, and new materials designed to prevent rejection. The ERC has a significantly reformed engineering education effort with foci on undergraduate and graduate engineering with a BME application focus. These reform efforts combine the collaborative expertise of the universitys school of engineering, a school of medicine and a school of education. The engineering educational reform efforts combine undergraduate and graduate coursework with comprehensive, innovative, and multidisciplinary laboratory experiences aligned to the ERCs BME test beds for all students. Students have opportunities to engage in powerful research side-by-side premiere researchers using aninductively based, situated approach to curriculum and instruction. The ERCs engineering educational approaches address four broad themes: Access, Inductively based Situated Learning, Retention and Career outcomes. This paper reports both on baseline access, retention, and career data and a logic model associated with a comprehensive curricular reform resulting from the access, retention and career baseline data. As a result of this baseline data, the ERC educational team has found innovative ways to infuse inductively based, situated curriculum and instruction in addition to a student-centric outcome metrics into all aspects of the BME curriculum and associated laboratory experiences. These assessment measures build on the principles established in educational psychology and include pre and posttest BME concept inventories, rubric-based laboratory assessments, BME efficacy measures and employer satisfaction measures. A comprehensive assessment profile is in the process of being created for program graduates at both the graduate and undergraduate levels. This ASEE paper is a work in progress report as the engineering education reform engaged in via the ERC represents a comprehensive reform process incorporated in to NSF engineering research center funding that extends for a ten year period.

However, this collaboration can cause problems because of the complex environments, the fight for limited resources and uncoordinated management, all of which result in poor service delivery to the communities, adding to their woes. From extensive field research and case studies conducted in the post-Wenchuan earthquake-stricken communities, this paper introduces an integrated collaboration framework for community post-disaster reconstruction with the focus on three types of NGOs: international, government organised and civil. The proposed collaboration framework examines the three interrelated components of organisational structure, operational processes and reconstruction goals/implementation areas. Of great significance in better promoting collaborative participation between NGOs are the crucial concepts of participatory reconstruction, double-layer collaborative networks, and circular review and revision.

  14. Earthquake Prediction

    NSDL National Science Digital Library

    Earthquake prediction has never been an exact science or an easy job. In 1923, the debate between two Japanese seismologists, Akitune Imamura, and his superior at the University of Tokyo, Professor Omori, over whether a great earthquake was imminent, ended in tragedy as Omori prevailed and no preparations were made for the disaster. In this video segment, a contemporary seismologist tells the story of these two pioneers and describes the events of the Kanto Earthquake, in which 140,000 people were killed. The segment is two minutes fifty-seven seconds in length. A background essay and discussion questions are included.

  16. Earthquakes Living Lab: Finding Epicenters and Measuring Magnitudes

    NSDL National Science Digital Library

    Civil and Environmental Engineering Department,

    Students learn how engineers characterize earthquakes through seismic data. Then, acting as engineers, they use real-world seismograph data and a tutorial/simulation accessed through the Earthquakes Living Lab to locate earthquake epicenters via triangulation and determine earthquake magnitudes. Student pairs examine seismic waves, S waves and P waves recorded on seismograms, measuring the key S-P interval. Students then determine the maximum S wave amplitudes in order to determine earthquake magnitude, a measure of the amount of energy released. Students consider how engineers might use and implement seismic data in their design work. A worksheet serves as a student guide for the activity.

    Mandi?, Vladimir; Markkula, Jouni; Oivo, Markku

    This paper presents results of a literature analysis on Empirical Research Approaches in Software Engineering (SE). The analysis explores reasons why traditional methods, such as statistical hypothesis testing and experiment replication are weakly utilized in the field of SE. It appears that basic assumptions and preconditions of the traditional methods are contradicting the actual situation in the SE. Furthermore, we have identified main issues that should be considered by the researcher when selecting the research approach. In virtue of reasons for weak utilization of traditional methods we propose stronger use of Multi-Method approach with Pragmatism as the philosophical standpoint.

    2009-04-01

    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 .

    Our undergraduate research program, SCEC/UseIT, an NSF Research Experience for Undergraduates site, provides software for earthquake researchers and educators, movies for outreach, and ways to strengthen the technical career pipeline. SCEC/UseIT motivates diverse undergraduates towards science and engineering careers through team-based research in the exciting field of earthquake information technology. UseIT provides the cross-training in computer science/information technology (CS/IT) and geoscience needed to make fundamental progress in earthquake system science. Our high and increasing participation of women and minority students is crucial given the nation"s precipitous enrollment declines in CS/IT undergraduate degree programs, especially among women. UseIT also casts a "wider, farther" recruitment net that targets scholars interested in creative work but not traditionally attracted to summer science internships. Since 2002, SCEC/UseIT has challenged 79 students in three dozen majors from as many schools with difficult, real-world problems that require collaborative, interdisciplinary solutions. Interns design and engineer open-source software, creating increasingly sophisticated visualization tools (see "SCEC-VDO," session IN11), which are employed by SCEC researchers, in new curricula at the University of Southern California, and by outreach specialists who make animated movies for the public and the media.

    de Groot, R. M.; McGill, S. F.

    2011-12-01

    This EarthScope-funded project is a collaboration between high school science teachers and their students, undergraduate and graduate students, and faculty from California State University San Bernardino (CSUSB), University of Arizona, and the Southern California Earthquake Center (SCEC). As high school teachers and their students work alongside one another, they are exposed to and contribute to an authentic research process that will lead to publishable results. The scientific goal of this project is to measure plate tectonic movement within the San Bernardino mountain area and the Inland Empire region of Southern California utilizing the Global Positioning System (GPS). Teachers and high school students collected survey-mode GPS data from 11 sites (among a total of 25 sampled by the larger group of participants) during a 5-day campaign from July 14 -19, 2011. The information obtained will be useful for understanding and characterizing seismic hazards in that region of Southern California. To enhance this experience, all of the teachers and their students have been invited to present their results at the SCEC Annual Meeting in September 2011. As part of the classroom implementation phase of the program the teachers are introduced to the Lesson Study approach. Lesson Study is a professional development process where teachers systematically examine their practice with the goal of becoming more effective. This process centers on teachers working collaboratively on a small number of Research Lessons. First, they identify the areas where their students are encountering challenges in learning standards-based content. The challenging areas are identified through results from standardized exams (e.g. California Standards Tests) or other assessment tools. To address areas of difficulty the teachers develop, test, and improve an instructional experience that promotes student learning of that standards-based material. Lesson Study is different from "lesson planning" because it focuses on what teachers want students to learn rather than on what teachers plan to teach. The 2011 teachers divided into three groups and each group is developing a Research Lesson. One of each of the group members teaches the lesson while the others observe the student learning. After the Research Lesson is taught the entire group comes together to debrief the lesson, make revisions, and another member of the group re-teaches the lesson (at a later date and at a different school) to incorporate what has been learned. This presentation will discuss how the CSUSB project has developed a successful framework for providing teachers with a valuable research experience as well as allowing an opportunity for them to think systematically about their craft, learn from experience, and become members of a learning community of practice.

    2010-12-01

    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.

    A challenge facing the engineering community is to find ways to integrate older people into the labor force. Despite laws regarding age discrimination and compulsory retirement, older people's participation in the labor force is declining. Unless strategies are developed to keep older people in the workforce, the issues of economic dependency and intergenerational equity are likely to become formidable in the near future. There are a number of areas where engineering applications can enhance older adults' employment opportunities. These include training, workplace and equipment design, and job design. An overview of current knowledge regarding aging and work is provided. Gaps in the knowledge base are identified as areas for research. Examples of how engineering can contribute to the integration of older people into work settings are presented. PMID:7843213

    Englund, D. R.

    1986-01-01

    Programs to develop research instrumentation for use on hot section components of turbine engines are discussed. These programs can be separated into two categories: one category includes instruments which can measure the environment within the combustor and turbine components, the other includes instruments which measure the response of engine components to the imposed environment. Included in the first category are instruments to measure total heat flux and fluctuating gas temperature. High temperature strain measuring systems, thin film sensors (e.g., turbine blade thermocouples) and a system to view the interior of a combustor during engine operation are programs which comprise the second category. The paper will describe the state of development of these sensors and measuring systems and, in some cases, show examples of measurements made with this instrumentation. The discussion will cover work done at NASA Lewis and at various contractor facilities.

This report includes a historical perspective of the Center and the facilities used to conduct the research. Major noise research programs are highlighted to show their impact on industry and on the development of aircraft noise reduction technology. Noise reduction trends are discussed, and future aircraft concepts are presented. Since the 1960s, research results show that the average perceived noise level has been reduced by about 20 decibels (dB). Studies also show that, depending on the size of the airport, the aircraft fleet mix, and the actual growth in air travel, another 15 to 17 dB reduction will be required to achieve NASAs long-term goal of providing technologies to limit objectionable noise to the boundaries of an average airport.

    Connie Smith-Holbert; Joseph Petrolino; Bart Watkins; David Irick

    2011-12-31

    The Legacy engine is a completely new design, transitional diesel engine, replacing the reciprocating engine with a rotary engine. The Legacy engine offers significant advances over conventional internal combustion engines in 1) power to weight ratio; 2) multiple fuel acceptance; 3) fuel economy; and 4) environmental compliance. These advances are achieved through a combination of innovative design geometry, rotary motion, aspiration simplicity, and manufacturing/part simplicity. The key technical challenge to the Legacy engine??s commercialization, and the focus of this project, was the development of a viable roton tip seal. The PST concept for the roton tip seal was developed into a manufacturable design. The design was evaluated using a custom designed and fabricated seal test fixture and further refined. This design was incorporated into the GEN2.5A prototype and tested for achievable compression pressure. The Decision Point at the end of Phase 1 of the project (described below) was to further optimize the existing tip seal design. Enhancements to the tip seal design were incorporated into the GEN2.5B prototype and tested and evaluated using the iterative research strategy described below. Compression pressures adequate for compression ignition of diesel fuel were achieved, although not consistently in all combustion volumes. The variation in compression pressures was characterized versus design features. As the roton tip seal performance was improved, results pointed toward inadequate performance of the housing side seals. Enhancement of the housing side seal system was accomplished using a custom designed side seal test fixture. The design enhancements developed with the test fixture were also incorporated into the GEN2.5B prototype and tested and evaluated using the iterative research strategy described below. Finally, to simplify the requirements for the roton tip seals and to enhance the introduction and combustion of fuel, a flush-mount fuel injector was designed, manufactured and demonstrated in the GEN2.5B prototype.

    NASA Technical Reports Server (NTRS)

    Povinelli, Louis A.; Reichert, Bruce A.; Glassman, Arthur J.

    1992-01-01

    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.

    During the past 17 years, Young Engineers and Scientists (YES) has been a community partnership between local high schools in San Antonio, Texas (USA), and Southwest Research Institute (SwRI). The goals of YES are to increase the number of high school students, especially those from underrepresented groups, seeking careers in science and engineering and to enhance their success in entering the college and major of their choice. This is accomplished by expanding career awareness, including information on "hot" career areas through seminars and laboratory tours by SwRI staff, and allowing students to interact on a continuing basis with role models at SwRI in a real-world research experiences in physical sciences (including geosciences), information sciences, and a variety of engineering fields. YES consists of two parts: 1) An intensive three-week summer workshop held at SwRI where students experience the research environment and 2) a collegial mentorship where students complete individual research projects under the guidance of SwRI mentors during the academic year. At the end of the school year, students publicly present and display their work, spreading career awareness to other students and teachers. YES students develop a website (yesserver.space.swri.edu) for topics in space science and high school science teachers develop space-related lessons for classroom presentation. Partnerships between research institutes, local high schools, and community foundations, like the YES Program, can positively affect students preparation for STEM careers via real-world research experiences with mentorship teams consisting of professional staff and qualified teachers.

    Modern science has enabled experts in building process such as engineers and architects to prepare and organize earthquake provisions through building codes. However, having a modern earthquake code does not guarantee earthquake resistant buildings. The clarity of the codes, especially for architects, and code enforcement are other important factors that should be satisfied. Many scholars and practicing architects may think

  16. Undergraduate Research Co-op in Biomedical Engineering

    NSDL National Science Digital Library

    Collet, Jill

    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.

    The Ludian County of Yunnan Province in southwestern China was struck by an M S6.5 earthquake on August 3, 2014, which was another destructive event following the M S8.0 Wenchuan earthquake in 2008, M S7.1 Yushu earthquake in 2010, and M S7.0 Lushan earthquake in 2013. National Strong-Motion Observation Network System of China collected 74 strong motion recordings, which the maximum peak ground acceleration recorded by the 053LLT station in Longtoushan Town was 949 cm/s2 in E-W component. The observed PGAs and spectral ordinates were compared with ground-motion prediction equation in China and the NGA-West2 developed by Pacific Earthquake Engineering Researcher Center. This earthquake is considered as the first case for testing applicability of NGA-West2 in China. Results indicate that the observed PGAs and the 5 % damped pseudo-response spectral accelerations are significantly lower than the predicted ones. The field survey around some typical strong motion stations verified that the earthquake damage was consistent with the official isoseismal by China Earthquake Administration.

  18. 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.

  19. The Alaska earthquake, March 27, 1964: lessons and conclusions

    One of the greatest earthquakes of all time struck south-central Alaska on March 27, 1964. Strong motion lasted longer than for most recorded earthquakes, and more land surface was dislocated, vertically and horizontally, than by any known previous temblor. Never before were so many effects on earth processes and on the works of man available for study by scientists and engineers over so great an area. The seismic vibrations, which directly or indirectly caused most of the damage, were but surface manifestations of a great geologic event-the dislocation of a huge segment of the crust along a deeply buried fault whose nature and even exact location are still subjects for speculation. Not only was the land surface tilted by the great tectonic event beneath it, with resultant seismic sea waves that traversed the entire Pacific, but an enormous mass of land and sea floor moved several tens of feet horizontally toward the Gulf of Alaska. Downslope mass movements of rock, earth, and snow were initiated. Subaqueous slides along lake shores and seacoasts, near-horizontal movements of mobilized soil (landspreading), and giant translatory slides in sensitive clay did the most damage and provided the most new knowledge as to the origin, mechanics, and possible means of control or avoidance of such movements. The slopes of most of the deltas that slid in 1964, and that produced destructive local waves, are still as steep or steeper than they were before the earthquake and hence would be unstable or metastable in the event of another great earthquake. Rockslide avalanches provided new evidence that such masses may travel on cushions of compressed air, but a widely held theory that glaciers surge after an earthquake has not been substantiated. Innumerable ground fissures, many of them marked by copious emissions of water, caused much damage in towns and along transportation routes. Vibration also consolidated loose granular materials. In some coastal areas, local subsidence was superimposed on regional tectonic subsidence to heighten the flooding damage. Ground and surface waters were measurably affected by the earthquake, not only in Alaska but throughout the world. Expectably, local geologic conditions largely controlled the extent of structural damage, whether caused directly by seismic vibrations or by secondary effects such as those just described. Intensity was greatest in areas underlain by thick saturated unconsolidated deposits, least on indurated bedrock or permanently frozen ground, and intermediate on coarse well-drained gravel, on morainal deposits, or on moderately indurated sedimentary rocks. Local and even regional geology also controlled the distribution and extent of the earthquake's effects on hydrologic systems. In the conterminous United States, for example, seiches in wells and bodies of surface water were controlled by geologic structures of regional dimension. Devastating as the earthquake was, it had many long-term beneficial effects. Many of these were socioeconomic or engineering in nature; others were of scientific value. Much new and corroborative basic geologic and hydrologic information was accumulated in the course of the earthquake studies, and many new or improved investigative techniques were developed. Chief among these, perhaps, were the recognition that lakes can be used as giant tiltmeters, the refinement of methods for measuring land-level changes by observing displacements of barnacles and other sessile organisms, and the relating of hydrology to seismology by worldwide study of hydroseisms in surface-water bodies and in wells. The geologic and hydrologic lessons learned from studies of the Alaska earthquake also lead directly to better definition of the research needed to further our understanding of earthquakes and of how to avoid or lessen the effects of future ones. Research is needed on the origins and mechanisms of earthquakes, on crustal structure, and on the generation of tsunamis and local waves. Better earthquake-hazard maps, based on improved knowledge of regional geology, faul

    2015-04-01

    We present a review on the research regarding the possible sources of the largest historical tsunamis hitting the Italian coasts and following large magnitude earthquakes. Although it is known that tsunamis are rather rare events, especially when compared to earthquakes, we emphasize that 6 out of 10 earthquakes occurred in the last thousand years in Italy, and having equivalent moment magnitude equal or larger than 7 where accompanied by destructive or heavily damaging tsunamis: the percentage is still significant (around 40%) if we extend the lower limit of the equivalent moment magnitude down to 6.5. The most famous of these events are those occurred on 30 July 1627 in Gargano, on 11 January 1693 in eastern Sicily, and on 28 December 1908 in the Messina Straits. Maximum run-ups in the order of 10 m, significant maximum inundation distances, and large (although not precisely quantifiable) numbers of victims are reported, or can be deduced from coeval sources. Analyses carried out on paleo-tsunami deposits in the impacted regions and published over the last decade help to better characterise the tsunami impact, confirming that none of the cited events can be reduced to local or secondary effects. Hence, we point out the importance of including a proper analysis and simulation of tsunami data in the approach to a correct definition of the sources responsible for the largest Italian tsunamigenic earthquakes. Unfortunately, this is not the usual practice, as macroseismic, seismic and geological/geomorphological observations and data typically are assigned much heavier weights; one of the consequences is that in-land faults are often assigned larger credit than the offshore ones, and the tsunami generation is imputed a-priori to only supposed, and sometimes even non-existing, submarine landslides. We try to summarise the tsunami research point of view on the largest Italian historical tsunamigenic earthquakes, having in mind that the different datasets analysed by different disciplines must be reconciled rather than put into contrast with each other: we highlight the open problems, trying to suggest the possible answers that tsunami observations and simulations can contribute towards their solution. This study is funded in the frame of the EU Project called ASTARTE - Assessment, STrategy And Risk Reduction for Tsunamis in Europe. Grant 603839, 7th FP (ENV.2013.6.4-3).

    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.

    NIMR(National Institute of Meteorological Researches) published historic earthquake catalogs of Korean Peninsula recently. This catalog contains 2161 events recorded at historic documents such as annals of the Jo-seon dynasty and the chronicles of 3 countries. Among those events, 440 earthquakes classified as intensity greater than 5(Korea intensity scale) and 15 earthquakes having intensity between 8 to 10(Korea intensity scale) are interpreted as damaging earthquake. Kyung-Ju earthquake occurred at 779 was the greatest one with M 6.7 and killed 100 people written by historic records. Several records contained the information of damage and casualties from possible Tsunami event. The purpose of making earthquake catalog is to define potential earthquake hazard of Korean Peninsula. As a result of collecting earthquake records for last 2000 years, the Intensity population distribution of historic earthquake marked similar to that of present instrumental earthquake record of KMA bulletin.

    The U.S. Army Vehicle Technology Directorate at the NASA Glenn Research Center has been directed by their parent command, the U.S. Army Research Laboratory (ARL), to demonstrate active stall technology in a turboshaft engine as the next step in transitioning this technology to the Army and aerospace industry. Therefore, the Vehicle Technology Directorate requested the reactivation of Glenn's Engine Components Research Lab, Cell 2B, (ECRL 2B). They wanted to test a T700 engine that had been used previously for turboshaft engine research as a partnership between the Army and NASA on small turbine engine research. ECRL 2B had been placed in standby mode in 1997. Glenn's Testing Division initiated reactivation in May 2002 to support the new research effort, and they completed reactivation and improvements in September 2003.

    The March 11, 2011 Tohoku earthquake and its tsunami killed 18,508 people, including the missing (National Police Agency report as of April 2014) and raise the Level 7 accident at TEPCO's Fukushima Dai-ichi nuclear power station in Japan. The problems revealed can be viewed as due to a combination of risk-management, risk-communication, and geoethics issues. Japan's preparations for earthquakes and tsunamis are based on the magnitude of the anticipated earthquake for each region. The government organization coordinating the estimation of anticipated earthquakes is the "Headquarters for Earthquake Research Promotion" (HERP), which is under the Ministry of Education, Culture, Sports, Science and Technology (MEXT). Japan's disaster mitigation system is depicted schematically as consisting of three layers: seismology, civil engineering, and disaster mitigation planning. This research explains students in geoscience should study geoethics as part of their education related Tohoku earthquake and the Level 7 accident at TEPCO's Fukushima Dai-ichi nuclear power station. Only when they become practicing professionals, they will be faced with real geoethical dilemmas. A crisis such as the 2011 earthquake, tsunami, and Fukushima Dai-ichi nuclear accident, will force many geoscientists to suddenly confront previously unanticipated geoethics and risk-communication issues. One hopes that previous training will help them to make appropriate decisions under stress. We name it "decision science".

  14. Integrating Global Hydrology Into Graduate Engineering Education and Research

    2007-12-01

    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.

    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.
