Understanding the physical behavior of volcanoes is key to mitigating the hazards active volcanoes pose to the ever-increasing populations living nearby. The processes involved in volcanic eruptions are driven by a series of interlinked physical phenomena, and to fully understand these, volcanologists must employ various physics subdisciplines. This book provides the first advanced-level, one-stop resource examining the physics of volcanic behavior and reviewing the state-of-the-art in modeling volcanic processes. Each chapter begins by explaining simple modeling formulations and progresses to present cutting-edge research illustrated by case studies. Individual chapters cover subsurface magmatic processes through to eruption in various environments and conclude with the application of modeling to understanding the other volcanic planets of our Solar System. Providing an accessible and practical text for graduate students of physical volcanology, this book is also an important resource for researchers and professionals in the fields of volcanology, geophysics, geochemistry, petrology and natural hazards.

Japan, which is among the most earthquake-prone regions in the world, has a long history of responding to seismic disasters. However, despite advances in earthquake-related safety technologies, the destructiveness of the magnitude 9 class earthquake and tsunami that struck the country on 3/11 raised profound questions about how societies can deal effectively with seismic hazards. This important book places the devastating earthquake, tsunami, and nuclear meltdown disaster in historical perspective, examining conceptions of earthquakes since the seventeenth century, the diverse ways actual earthquakes and their aftermath played out, and their enduring social and scientific significance. By looking backward, Gregory Smits identifies future pitfalls to avoid and assesses the allocation of resources for dealing with future earthquake and tsunami disasters. He criticizes Japan's postwar quest for earthquake prediction and the concept of "characteristic" earthquakes. Smits argues that earthquakes are so chaotic as to be unpredictable, not only geologically but also in their social and cultural effects. Therefore, he contends, the best hope for future disaster mitigation is antiseismic engineering and flexible disaster-relief capabilities. As the first sustained historical analysis of destructive earthquakes and tsunamis, this book is an essential resource for anyone interested in Japan, natural disasters, seismology, and environmental history.

Exploiting Seismic Waveforms introduces a range of recent developments in seismology including the application of correlation techniques, understanding of multi-scale heterogeneity and the extraction of structure and source information by seismic waveform inversion. It provides a full treatment of correlation methods for seismic noise and event signals, and develops inverse methods for both sources and structure. Higher frequency components of seismograms are frequently neglected, or removed by filtering, but they contain information about seismic structure on scales that cannot be revealed by seismic tomography. Sufficient computational resources are now available for waveform inversion for 3-D structure to be a practical procedure and this book describes suitable algorithms and examples reflecting current best practice. Intended for students and researchers in seismology, this book provides a physical understanding of seismic waveforms and the way that different aspects of the seismic wavefield are revealed by the way that seismic data are handled.

The relatively young theory of structured dependence between stochastic processes has many real-life applications in areas including finance, insurance, seismology, neuroscience, and genetics. With this monograph, the first to be devoted to the modeling of structured dependence between random processes, the authors not only meet the demand for a solid theoretical account but also develop a stochastic processes counterpart of the classical copula theory that exists for finite-dimensional random variables. Presenting both the technical aspects and the applications of the theory, this is a valuable reference for researchers and practitioners in the field, as well as for graduate students in pure and applied mathematics programs. Numerous theoretical examples are included, alongside examples of both current and potential applications, aimed at helping those who need to model structured dependence between dynamic random phenomena.

Volcanic eruptions are the most spectacular displays in the natural world. They also present humanity with devastating environmental disasters. This enthralling book describes fifteen of the most remarkable volcanic eruptions across the centuries and, using rare firsthand accounts, analyzes their impact on the people in their paths. In 79 a.d. Vesuvius produced the most violent eruption recorded in European history. The eruption of Etna in 1669 marked the first known attempt to divert a lava-flow. In 1783, the eruption of Laki indirectly killed a fifth of the Icelandic population and sent a blue haze over Europe. The eruption of Krakatau in 1883 drowned most of its victims and destroyed much of the island as well. In 1980 Mount St. Helens produced a new type of eruption and scythed down a majestic forest. Alwyn Scarth explores these and other eruptions, reconstructing the physical experience of the disaster, its origins, explosion, and aftermath, and interpreting (in many cases for the first time in English) eyewitness accounts that bring their own vividness to the unfolding drama. The accounts tell of fear, panic, miscalculation, and inefficiency as well as emergency organization, self-sacrifice, religious fervor, and heroism, revealing how each affected population handled-or mishandled-its crisis. Scarth's riveting survey shows that technology and volcanic surveillance have made enormous strides during the present century. But volcanoes remain indomitable: no one has yet learned how an eruption can be stopped.

When Indonesia's Mount Tambora erupted in 1815, it unleashed the most destructive wave of extreme weather the world has witnessed in thousands of years. The volcano's massive sulfate dust cloud enveloped the Earth, cooling temperatures and disrupting major weather systems for more than three years. Communities worldwide endured famine, disease, and civil unrest on a catastrophic scale. Here, Gillen D'Arcy Wood traces Tambora's global and historical reach: how the volcano's three-year climate change regime initiated the first worldwide cholera pandemic, expanded opium markets in China, and plunged the United States into its first economic depression. Bringing the history of this planetary emergency to life, Tambora sheds light on the fragile interdependence of climate and human societies to offer a cautionary tale about the potential tragic impacts of drastic climate change in our own century.

The past few decades have witnessed remarkable growth in the application of passive seismic monitoring to address a range of problems in geoscience and engineering, from large-scale tectonic studies to environmental investigations. Passive seismic methods are increasingly being used for surveillance of massive, multi-stage hydraulic fracturing and development of enhanced geothermal systems. The theoretical framework and techniques used in this emerging area draw on various established fields, such as earthquake seismology, exploration geophysics and rock mechanics. Based on university and industry courses developed by the author, this book reviews all the relevant research and technology to provide an introduction to the principles and applications of passive seismic monitoring. It integrates up-to-date case studies and interactive online exercises, making it a comprehensive and accessible resource for advanced students and researchers in geophysics and engineering, as well as industry practitioners.

Providing the first worldwide survey of active earthquake faults, this book focuses on those described as 'seismic time bombs' - with the potential to destroy large cities in the developing world such as Port au Prince, Kabul, Tehran and Caracas. Leading international earthquake expert, Robert Yeats, explores both the regional and plate-tectonic context of active faults, providing the background for seismic hazard evaluation in planning large-scale projects such as nuclear power plants or hydroelectric dams. He also highlights work done in more advanced seismogenic countries like Japan, the United States, New Zealand and China, providing an important basis for upgrading building standards and other laws in developing nations. The book also explores the impact of major quakes on social development through history. It will form an accessible reference for analysts and consulting firms, and a convenient overview for academics and students of geoscience, geotechnical engineering and civil engineering, and land-use planning.

Extracting information from seismic data requires knowledge of seismic wave propagation and reflection. The commonly used method involves solving linearly for a reflectivity at every point within the Earth, but this book follows an alternative approach which invokes inverse scattering theory. By developing the theory of seismic imaging from basic principles, the authors relate the different models of seismic propagation, reflection and imaging - thus providing links to reflectivity-based imaging on the one hand and to nonlinear seismic inversion on the other. The comprehensive and physically complete linear imaging foundation developed presents new results at the leading edge of seismic processing for target location and identification. This book serves as a fundamental guide to seismic imaging principles and algorithms and their foundation in inverse scattering theory, and is a valuable resource for working geoscientists, scientific programmers and theoretical physicists.

Intraplate earthquakes occur away from tectonic plate boundaries: their locations are difficult to predict, risking huge damage and loss of life. The 2001 Bhuj earthquake (featured in this book) was the largest intraplate earthquake for three decades and has provided unique insight into these events. This cutting-edge book brings together research from international leading experts in the field. Each chapter provides a comprehensive review of these earthquakes in a different global location, ranging from Australia, China, India and the Sea of Japan, to Western Europe, Brazil, New Madrid (Central USA), and Eastern Canada. They explore similarities and differences between regional features and the mechanical models required to explain them, as well as assessing geophysical techniques used to investigate them. Providing the first global overview of intraplate earthquakes, this is an essential book for academic researchers and professionals in seismology, tectonics, tectonophysics, geodesy, structural geology, earthquake dynamics, geophysics, and structural engineering.

The characterisation of fluid transport properties of rocks is one of the most important, yet difficult, challenges of reservoir geophysics, but is essential for optimal development of hydrocarbon and geothermal reservoirs. This book provides a quantitative introduction to the underlying physics, application, interpretation, and hazard aspects of fluid-induced seismicity with a particular focus on its spatio-temporal dynamics. It presents many real data examples of microseismic monitoring of hydraulic fracturing at hydrocarbon fields and of stimulations of enhanced geothermal systems. The author also covers introductory aspects of linear elasticity and poroelasticity theory, as well as elements of seismic rock physics and mechanics of earthquakes, enabling readers to develop a comprehensive understanding of the field. Fluid-Induced Seismicity is a valuable reference for researchers and graduate students working in the fields of geophysics, geology, geomechanics and petrophysics, and a practical guide for petroleum geoscientists and engineers working in the energy industry.

This handbook defines the discipline of historical seismology by detailing the latest research methodologies for studying historical earthquakes and tsunamis. It describes the various sources that reference seismic phenomena, discusses the critical problems of interpreting such sources, and presents a summary of the theories proposed throughout history to explain the causes of earthquakes. Incorporating examples from a broad geographic region, including Europe, North Africa, the Middle East, central Asia, and the Americas, the text presents numerous interpretations and misinterpretations of historical earthquakes and tsunamis in order to illustrate the key techniques. The authors also tie historical seismology research to archaeological investigations, and demonstrate how new scientific databases and catalogues can be compiled from information derived from the methodologies described. This is an important new reference for scientists, engineers, historians and archaeologists, providing a valuable foundation for understanding the Earth's seismic past and potential future seismic hazard.

The inner core is a planet within a planet: a hot sphere with a mass of one hundred quintillion tons of iron and nickel that lies more than 5000 kilometres beneath our feet. It plays a crucial role in driving outer core fluid motion and the geodynamo, which generates the Earth's magnetic field. This book is the first to provide a comprehensive review of past and contemporary research on the Earth's inner core from a seismological perspective. Chapters cover the collection, processing and interpretation of seismological data, as well as our current knowledge of the structure, anisotropy, attenuation, rotational dynamics, and boundary of the inner core. Reviewing the latest research and suggesting new seismological techniques and future avenues, it is an essential resource for both seismologists and non-seismologists interested in this fascinating field of research. It will also form a useful resource for courses in seismology and deep Earth processes.

This book introduces a methodology for solving the seismic inverse problem using purely numerical solutions built on 3D wave equations and which is free of the approximations or simplifications that are common in classical seismic inversion methodologies and therefore applicable to arbitrary 3D geological media and seismic source models. Source codes provided allow readers to experiment with the calculations demonstrated and also explore their own applications.

Serendipity placed David Johnston on Mount St. Helens when the volcano rumbled to life in March 1980. Throughout that ominous spring, Johnston was part of a team that conducted scientific research that underpinned warnings about the mountain. Those warnings saved thousands of lives when the most devastating volcanic eruption in U.S. history blew apart Mount St. Helens, but killed Johnston on the ridge that now bears his name. Melanie Holmes tells the story of Johnston's journey from a nature-loving Boy Scout to a committed geologist. Blending science with personal detail, Holmes follows Johnston through encounters with Aleutian volcanoes, his work helping the Portuguese government assess the geothermal power of the Azores, and his dream job as a volcanologist with the U.S. Geological Survey. Interviews and personal writings reveal what a friend called "the most unjaded person I ever met," an imperfect but kind, intelligent young scientist passionately in love with his life and work and determined to make a difference.
