This book was released on 2015 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquefaction induced lateral spreading during earthquakes poses a significant hazard to infrastructure and has severe consequences. It is critical for geotechnical earthquake engineers to be able to accurately predict lateral spread movements. Empirical and semi-empirical models and various liquefaction index parameters are available to help predict the potential for damage and movements associated with liquefaction and lateral spreading. In this thesis, the available models and liquefaction index parameters were investigated using the observed lateral spread displacements from the Christchurch earthquake in New Zealand. The analysis includes investigation of the Youd et al. (2002), Bardet et al. (2002), Rauch and Martin (2000) and Zhang et al. (2004) displacement models; and the liquefaction potential index (LPI), settlement indicator (Sv1d) and liquefaction severity number (LSN) parameters. The results of this study show that both the Youd et al. (2002) and Bardet et al. (2002) models predict lateral spread displacements much smaller than observed in Christchurch, most likely due to the relatively small magnitude of the Christchurch earthquake (M[subscript w] = 6.2) relative to the earthquake magnitudes included in datasets used to develop the Youd et al. (2002) and Bardet et al. (2002) models (i.e., Mw >= 7.5). The Rauch and Martin (2000) and Zhang et al. (2004) models predicted lateral spread displacements more similar to those observed. The Rauch and Martin (2000) model predicts the average lateral spread displacement over an entire slide area, as opposed to predicting lateral spread displacement at a point, which may have contributed to the more favorable comparison.

This book was released on 2021 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: For 50 years, significant investments have been made to develop models that predict soil liquefaction. Many of the results may be described as either: (i) wholly empirical models that require only geologic or geospatial data, and which are accessible to a broad userbase; or (ii) semi-mechanistic "simplified stress-based" models that are based on in-situ tests, and which are generally limited to use by geoengineers, with cone-penetration-test (CPT) based models currently considered best. While these models are widely used, all to-date were trained on modest datasets (e.g., 250 datapoints) and in general, have not been rigorously tested against unbiased data, or against one other. In addition, relative to predicting liquefaction occurrence, less effort has historically been given to predicting the downstream consequences of liquefaction, such as damage and loss. As a result, decisions about whether, and how, to mitigate liquefaction must generally be made in a heuristic manner. Meanwhile, recent earthquakes in the age of improved satellite remote sensing and reconnaissance have significantly grown the data that could be used to model liquefaction and its effects, including ground settlement, foundation deformation, and insured losses. Moreover, the growth of remote sensing, in combination with emergent machine- and deep-learning algorithms, creates an opportunity to develop a new type of model that provides rapid, regional predictions of seismic impacts without the need to sample individual sites. Thus, the overarching goal of this work is to test and develop liquefaction occurrence and consequence analytics using emerging data and technologies. Namely, through ten objectives, this research aims to: (1) digitize and publicly compile all existing liquefaction case-histories where CPTs were performed, of which there are ~275, and which may be used to train or test CPT-based liquefaction models; and (2) grow the quantity of such cases to ~15,000 using data from earthquakes in New Zealand. These datasets will then be used to: (3) test existing liquefaction-prediction models based on either the CPT or on geospatial data, from which lessons for future improvement are identified; (4) test a new procedure for correcting "thin layer effects" on CPT data in the context of liquefaction model performance; (5) test existing CPT models that predict ground settlement induced by liquefaction; and (6) train new fragility functions that probabilistically predict liquefaction-induced ground failure. Using the data compiled in (2), in conjunction with additional foundation damage surveys and insurance loss assessments from New Zealand, a decision framework for mitigating liquefaction beneath buildings on shallow foundations is (7) proposed; and demonstrated. Using insights from the tests in (3), a next-generation geospatial modelling approach is (8) proposed, trained, tested, and (9) programmed wherein machine- and deep-learning are used to predict below-ground CPT data via above-ground geospatial information. Lastly, existing and newly proposed analytics in (1-7) are (10) programmed in Horizon, a program for analyzing the occurrence, consequence, and mitigation of liquefaction.

Download or read book The Orphan Tsunami of 1700 written by Brian F. Atwater and published by University of Washington Press. This book was released on 2016-04-18 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: A puzzling tsunami entered Japanese history in January 1700. Samurai, merchants, and villagers wrote of minor flooding and damage. Some noted having felt no earthquake; they wondered what had set off the waves but had no way of knowing that the tsunami was spawned during an earthquake along the coast of northwestern North America. This orphan tsunami would not be linked to its parent earthquake until the mid-twentieth century, through an extraordinary series of discoveries in both North America and Japan. The Orphan Tsunami of 1700, now in its second edition, tells this scientific detective story through its North American and Japanese clues. The story underpins many of today�s precautions against earthquake and tsunami hazards in the Cascadia region of northwestern North America. The Japanese tsunami of March 2011 called attention to these hazards as a mirror image of the transpacific waves of January 1700.

Download or read book Disaster Hits Home written by Mary C. Comerio and published by Univ of California Press. This book was released on 2023-12-22 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whenever a major earthquake strikes or a hurricane unleashes its fury, the devastating results fill our television screens and newspapers. Mary C. Comerio is interested in what happens in the weeks and months after such disasters, particularly in the recovery of damaged housing. Through case studies of six recent urban disasters—Hurricane Hugo in South Carolina, Hurricane Andrew in Florida, the Loma Prieta and Northridge earthquakes in California, as well as earthquakes in Mexico City and Kobe, Japan—Comerio demonstrates that several fundamental factors have changed in contemporary urban disasters. The foremost change is in scale, and as more Americans move to the two coasts, future losses will continue to be formidable because of increased development in these high-hazard areas. Moreover, the visibility of disasters in the news media will assure that response efforts remain highly politicized. And finally, the federal government is now expected to be on the scene with personnel, programs, and financial assistance even as private insurance companies are withdrawing disaster coverage from homeowners in earthquake- and hurricane-prone regions. Demonstrating ways that existing recovery systems are inadequate, Comerio proposes a rethinking of what recovery means, a comprehensive revision of the government's role, and more equitable programs for construction financing. She offers new criteria for a housing recovery policy as well as real financial incentives for preparedness, for limiting damage before disasters occur, and for providing a climate where private insurance can work. Her careful analysis makes this book important reading for policymakers, property owners, and anyone involved in disaster mitigation.
Download or read book Submarine Landslides and Tsunamis written by Ahmet C. Yalçiner and published by Springer Science & Business Media. This book was released on 2003-12-31 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tsunamis are water waves triggered by impulsive geologic events such as sea floor deformation, landslides, slumps, subsidence, volcanic eruptions and bolide impacts. Tsunamis can inflict significant damage and casualties both nearfield and after evolving over long propagation distances and impacting distant coastlines. Tsunamis can also effect geomorphologic changes along the coast. Understanding tsunami generation and evolution is of paramount importance for protecting coastal population at risk, coastal structures and the natural environment. Accurately and reliably predicting the initial waveform and the associated coastal effects of tsunamis remains one of the most vexing problems in geophysics, and -with few exceptions- has resisted routine numerical computation or data collection solutions. While ten years ago, it was believed that the generation problem was adequately understood for useful predictions, it is now clear that it is not, especially nearfield. By contrast, the runup problem earlier believed intractable is now well understood for all but the most extreme breaking wave events.

This book was released on 2002 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthquake engineering is the ultimate challenge for structural engineers. Even if natural phenomena such as earthquakes involve great uncertainties, structural engineers need to design buildings, bridges, and dams capable of resisting the destructive forces produced by earthquakes. However, structural engineers must rely on the expertise of other specialists to realize these projects. Thus, this book not only focuses on structural analysis and design, but also discusses other disciplines, such as geology, seismology, and soil dynamics, providing basic knowledge in these areas so that structural engineers can better interact with different specialists when working on earthquake engineering projects."

Available in PDF, EPUB and Kindle. Book excerpt: This edited review book on Godunov methods contains 97 articles, all of which were presented at the international conference on Godunov Methods: Theory and Applications, held at Oxford in October 1999, to commemo rate the 70th birthday of the Russian mathematician Sergei K. Godunov. The meeting enjoyed the participation of 140 scientists from 20 countries; one of the participants commented: everyone is here, meaning that virtu ally everybody who had made a significant contribution to the general area of numerical methods for hyperbolic conservation laws, along the lines first proposed by Godunov in the fifties, was present at the meeting. Sadly, there were important absentees, who due to personal circumstance could not at tend this very exciting gathering. The central theme o{ the meeting, and of this book, was numerical methods for hyperbolic conservation laws fol lowing Godunov's key ideas contained in his celebrated paper of 1959. But Godunov's contributions to science are not restricted to Godunov's method.
Download or read book Seismic Design for Nuclear Power Plants written by Robert J. Hansen and published by MIT Press (MA). This book was released on 1970 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of protective measures to guard against the spread of radioactive debris following reactor disasters has been given extensive and careful engineering attention over the past several years. Much of this attention has been devoted to eliminating or minimizing the effects of malfunctions of internal components. But reactors can also suffer externally caused disasters—for example, their radioactive cores can be damaged by earthquakes or by missiles generated by tornadoes. Earthquakes in particular will continue to render man vulnerable even to the "peaceful atom" as the number of nuclear power plants increases and as they come to be located in those parts of the world that have a history of seismic activity. It was to consider such problems that the seminar reported here was held. The conferees, who are leaders in this special and important field, gathered in Cambridge, Massachusetts, in spring 1969, to present the papers whose titles are listed below. Together they cover both the theoretical underpinnings of the subject and specific applications to nuclear reactors; they provide both useful summaries of what is known to date and some new thinking on the subject, not before published.
