Book Description
Earthquake-induced soil liquefaction (liquefaction) is a leading cause of earthquake damage worldwide. Liquefaction is often described in the literature as the phenomena of seismic generation of excess porewater pressures and consequent softening of granular soils. Many regions in the United States have been witness to liquefaction and its consequences, not just those in the west that people associate with earthquake hazards. Past damage and destruction caused by liquefaction underline the importance of accurate assessments of where liquefaction is likely and of what the consequences of liquefaction may be. Such assessments are needed to protect life and safety and to mitigate economic, environmental, and societal impacts of liquefaction in a cost-effective manner. Assessment methods exist, but methods to assess the potential for liquefaction triggering are more mature than are those to predict liquefaction consequences, and the earthquake engineering community wrestles with the differences among the various assessment methods for both liquefaction triggering and consequences. State of the Art and Practice in the Assessment of Earthquake-Induced Soil Liquefaction and Its Consequences evaluates these various methods, focusing on those developed within the past 20 years, and recommends strategies to minimize uncertainties in the short term and to develop improved methods to assess liquefaction and its consequences in the long term. This report represents a first attempt within the geotechnical earthquake engineering community to consider, in such a manner, the various methods to assess liquefaction consequences.

Book Description
Due to its high energy density, liquid hydrogen is one of the best alternative fuels. As such, Liquefaction: Analysis and Assessment introduces hydrogen liquefaction techniques and provides an outlook concerning common methodology. Basic and conventional cycles used for hydrogen liquefaction are reviewed, and industrial in-service hydrogen liquefaction plants are discussed.The severe accident at the Fukushima Dai-ichi nuclear power plant demonstrated that the phenomena caused by an earthquake may actually cause more disastrous consequences than the vibratory ground motion itself, one of these phenomena being soil liquefaction. The authors propose that an analysis of the liquefaction hazards and consequences should be performed for the safety analysis of nuclear plants.Lastly, the authors address how uncertainties in the liquefied natural gas market are growing as new producers, including the United States and Australia, emerge. In an effort to tackle these market uncertainties, process optimization is an essential part of the liquefied natural gas project. In this instance, an exergy-based method is demonstrated and assessed for both thermodynamic and cost objectives.

Book Description
This fully updated second edition provides an introduction to geotechnical earthquake engineering for first-year graduate students in geotechnical or earthquake engineering graduate programs with a level of detail that will also be useful for more advanced students as well as researchers and practitioners. It begins with an introduction to seismology and earthquake ground motions, then presents seismic hazard analysis and performance-based earthquake engineering (PBEE) principles. Dynamic soil properties pertinent to earthquake engineering applications are examined, both to facilitate understanding of soil response to seismic loads and to describe their practical measurement as part of site characterization. These topics are followed by site response and its analysis and soil–structure interaction. Ground failure in the form of soil liquefaction, cyclic softening, surface fault rupture, and seismically induced landslides are also addressed, and the book closes with a chapter on soil improvement and hazard mitigation. The first edition has been widely used around the world by geotechnical engineers as well as many seismologists and structural engineers. The main text of this book and the four appendices: • Cover fundamental concepts in applied seismology, geotechnical engineering, and structural dynamics. • Contain numerous references for further reading, allowing for detailed exploration of background or more advanced material. • Present worked example problems that illustrate the application of key concepts emphasized in the text. • Include chapter summaries that emphasize the most important points. • Present concepts of performance-based earthquake engineering with an emphasis on uncertainty and the types of probabilistic analyses needed to implement PBEE in practice. • Present a broad, interdisciplinary narrative, drawing from the fields of seismology, geotechnical engineering, and structural engineering to facilitate holistic understanding of how geotechnical earthquake engineering is applied in seismic hazard and risk analyses and in seismic design.

Book Description
This book represents a significant contribution to the area of earthquake data processing and to the development of region-specific magnitude correlations to create an up-to-date homogeneous earthquake catalogue that is uniform in magnitude scale. The book discusses seismicity analysis and estimation of seismicity parameters of a region at both finer and broader levels using different methodologies. The delineation and characterization of regional seismic source zones which requires reasonable observation and engineering judgement is another subject covered. Considering the complex seismotectonic composition of a region, use of numerous methodologies (DSHA and PSHA) in analyzing the seismic hazard using appropriate instruments such as the logic tree will be elaborated to explicitly account for epistemic uncertainties considering alternative models (for Source model, Mmax estimation and Ground motion prediction equations) to estimate the PGA value at bedrock level. Further, VS30 characterization based on the topographic gradient, to facilitate the development of surface level PGA maps using appropriate amplification factors, is discussed. Evaluation of probabilistic liquefaction potential is also explained in the book. Necessary backgrounds and contexts of the aforementioned topics are elaborated through a case study specific to India which features spatiotemporally varied and complex tectonics. The methodology and outcomes presented in this book will be beneficial to practising engineers and researchers working in the fields of seismology and geotechnical engineering in particular and to society in general.
