The past few decades have witnessed the growth of the Earth Sciences in the pursuit of knowledge and understanding of the planet that we live on. This development addresses the challenging endeavor to enrich human lives with the bounties of Nature as well as to preserve the planet for the generations to come. Solid Earth Geophysics aspires to define and quantify the internal structure and processes of the Earth in terms of the principles of physics and forms the intrinsic framework, which other allied disciplines utilize for more specific investigations. The first edition of the Encyclopedia of Solid Earth Geophysics was published in 1989 by Van Nostrand Reinhold publishing company. More than two decades later, this new volume, edited by Prof. Harsh K. Gupta, represents a thoroughly revised and expanded reference work. It brings together more than 200 articles covering established and new concepts of Geophysics across the various sub-disciplines such as Gravity, Geodesy, Geomagnetism, Seismology, Seismics, Deep Earth Processes, Plate Tectonics, Thermal Domains, Computational Methods, etc. in a systematic and consistent format and standard. It is an authoritative and current reference source with extraordinary width of scope. It draws its unique strength from the expert contributions of editors and authors across the globe. It is designed to serve as a valuable and cherished source of information for current and future generations of professionals.

This volume collects several extended articles from the first workshop on Best Practices in Physics-based Fault Rupture Models for Seismic Hazard Assessment of Nuclear Installations (BestPSHANI). Held in 2015, the workshop was organized by the IAEA to disseminate the use of physics-based fault-rupture models for ground motion prediction in seismic hazard assessments (SHA). The book also presents a number of new contributions on topics ranging from the seismological aspects of earthquake cycle simulations for source scaling evaluation, seismic source characterization, source inversion and physics-based ground motion modeling to engineering applications of simulated ground motion for the analysis of seismic response of structures. Further, it includes papers describing current practices for assessing seismic hazard in terms of nuclear safety in low seismicity areas, and proposals for physics-based hazard assessment for critical structures near large earthquakes. The papers validate and verify the models by comparing synthetic results with observed data and empirical models. The book is a valuable resource for scientists, engineers, students and practitioners involved in all aspects of SHA.

This is the first of two volumes devoted to earthquakes and multi-hazards around the Pacific Rim. The circum-Pacific seismic belt is home to roughly 80% of the world’s largest earthquakes, making it the ideal location for investigating earthquakes and related hazards such as tsunamis and landslides. Gathering 16 papers that cover a range of topics related to multi-hazards, the book is divided into three sections: earthquake physics, earthquake simulation and data assimilation, and multi-hazard assessment and earthquake forecasting models. The first section includes papers on laboratory-derived rheological parameters as well as seismic studies in the Gulf of California and China. In turn, the second section includes papers on improvements in earthquake simulators as well as the statistical methods used to evaluate their performance, automated methods for determining fault slip using near-field interferometric data, variabilities in earthquake stress drops in California, and the use of social media data to supplement physical sensor data when estimating local earthquake intensity. The final section includes a paper on probabilistic tsunami hazard assessment, several papers on time-dependent seismic hazard analysis around the Pacific Rim, and a paper on induced and triggered seismicity at the Geysers geothermal field in California. Rapid advances are being made in our understanding of multi-hazards, as well as the range of tools used to investigate them. This volume provides a representative cross-section of how state-of-the-art knowledge and tools are currently being applied to multi-hazards around the Pacific Rim. The material here should be of interest to scientists involved in all areas of multi-hazards, particularly seismic and tsunami hazards. In addition, it offers a valuable resource for students in the geosciences, covering a broad spectrum of topics related to hazard research.

Disaster Deferred

In the winter of 1811-12, a series of large earthquakes in the New Madrid seismic zone-often incorrectly described as the biggest ever to hit the United States-shook the Midwest. Today the federal government ranks the hazard in the Midwest as high as California's and is pressuring communities to undertake expensive preparations for disaster. Coinciding with the two-hundredth anniversary of the New Madrid earthquakes, Disaster Deferred revisits these earthquakes, the legends that have grown around them, and the predictions of doom that have followed in their wake. Seth Stein clearly explains the techniques seismologists use to study Midwestern quakes and estimate their danger. Detailing how limited scientific knowledge, bureaucratic instincts, and the media's love of a good story have exaggerated these hazards, Stein calmly debunks the hype surrounding such predictions and encourages the formulation of more sensible, less costly policy. Powered by insider knowledge and an engaging style, Disaster Deferred shows how new geological ideas and data, including those from the Global Positioning System, are painting a very different-and much less frightening-picture of the future.

Eine gefährdete Liebe, eine Familie im Konflikt, ein Roman voller Geschichten – vom Autor des Welterfolgs «Die Korrekturen» Eine Serie von Erdbeben erschüttert Boston. Als die Großmutter von Louis Holland dabei ums Leben kommt, entbrennt ein erbitterter Familienstreit um ihr Vermögen. Seine Freundin, die junge Seismologin Renée, bemüht sich unterdessen, die Ursachen des rätselhaften Bebens zu ergründen. Doch je näher sie ihrem Ziel kommt, desto heftiger gerät das moralische Fundament der Familie Holland ins Wanken. «Ein großer Roman. Eine der schönsten Liebesgeschichten dieser Zeit.» (Süddeutsche Zeitung) «Jonathan Franzen zeigt ungemein unterhaltsam und humorvoll, was die Stärken des amerikanischen Romans ausmacht. ‹Schweres Beben› ist ein weiteres gewichtiges Kapitel der Menschlichen Komödie.» (Literaturen) «Ein sprachgewaltiges Panorama.» (Die Welt) «Moralisch und zynisch, heftig und sanft, komisch und traurig zugleich. Als hätten Bob Dylan und The Clash zusammen einen Song geschrieben.» (die tageszeitung) «‹Schweres Beben› ist nicht nur ein spannender Ökokatastrophenthriller, sondern auch ein Liebes- und Familienroman.» (Frankfurter Allgemeine Sonntagszeitung)

Seismological Attenuation Without Q

"Seismological Attenuation without Q" represents a comprehensive and critical review of the present approach to describing the seismic-wave attenuation within the Earth. Starting from first physical principles, author Igor B. Morozov shows that the existing model of attenuation based on the concept of quality factor, or Q, is inadequate and represents only a phenomenological model. In most cases, Q should not be interpreted as a physical property of the Earth's medium. This text offers an alternate view developed using the concept of attenuation coefficient and illustrated using many theoretical and data examples. The new approach leads to significant advances in understanding the physics of Earth's anelasticity, measurement, and modeling attenuation of seismic waves. A systematic and hitherto unseen pattern of attenuation coefficients is recognized within a broad range of wave types and frequencies, which leads us to a general and clear picture of the attenuation structure of the Earth. At the same time, Morozov also elucidates a number of unsolved problems, such as numerical modeling and inversion for seismic attenuation and understanding its relation to the structure and the physical state of the deep Earth. Most notably, "Seismological Attenuation without Q" shows that the attenuation problem is significantly more complex than presented in the Q-based, visco-elastic model.
