In recent years there has been growing recognition that disaster risk cannot be reduced by focusing solely on physical hazards without considering factors that influence socio-economic impact. Vulnerability: the susceptibility to the damaging impacts of hazards, and resilience: the ability to recover, have become popular concepts in natural hazard and risk management. This book provides a comprehensive overview of the concepts of vulnerability and resilience and their application to natural hazards research. With contributions from both physical and social scientists it provides an interdisciplinary discussion of the different types of vulnerability and resilience, the links between them, and concludes with the remaining challenges and future directions of the field. Examining global case studies from the US coast to Austria, this is a valuable reference for researchers and graduate students working in natural hazard and risk reduction from both the natural and social sciences.

Understanding and specification of the higher altitudes of the atmosphere with global coverage over all local times is hampered by the challenges of obtaining direct measurements in the upper atmosphere. Methods to measure the properties of the atmosphere above the stratopause is an active area of scientific research. In this thesis, we revisit the use of infrasound as a passive remote sensing technique for the upper atmosphere. Signals from the Tungurahua volcano in Ecuador are used to investigate the behavior of the upper atmosphere. Depending on the atmospheric conditions, stratospheric, mesospheric and thermospheric arrivals are observed during intervals of explosive volcanic activity. It is found that the travel times and dominant frequencies of the thermospheric arrivals exhibit a coherent variability with periods equal to those of the tidal harmonics. Theoretical predictions using atmospheric specifications show that the stratospheric arrivals are predicted within 1 percent of the observed value. For thermospheric arrivals, this error can be as high as 10 percent. The error in thermospheric celerities is found to be in accord with the typical uncertainty in upper atmospheric winds. Given the observed response of the infrasound celerities to upper atmospheric tidal variability, it is suggested that infrasound observations may be used as an additional source of information to constrain the atmospheric specifications in the upper atmosphere. We present corrected wind profiles that have been obtained by minimizing misfits in traveltime and source location using a Bayesian statistics grid search algorithm. Additionally, a new numerical method has been developed to solve the problem of infrasound propagation in a stratified medium with background flow, based on a modal expansion.

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.

Earthquakes pose myriad dangers to heritage collections worldwide. This book provides an accessible introduction to these dangers and to the methodologies developed at the Getty and other museums internationally for mitigating seismic vulnerability. Conceived as a primer and reference, this abundantly illustrated volume begins with an engaging overview of explanations for earthquakes from antiquity to the nineteenth century. A series of chapters then addresses our modern understanding of seismic events and approaches for mitigating the damage they cause to heritage collections, covering such subjects as earthquake measurement, hazard analysis, the response of buildings and collections to seismic events, mount making, and risk assessment; short sections by specialists in seismic engineering complement the main text throughout. Readers will find a range of effective seismic mitigation measures, from simple low-cost approaches to complex base-isolation techniques. In bridging the gap between seismologists and seismic engineers, on the one hand, and collections care professionals, on the other, this volume will be of interest to conservators, registrars, designers, mount makers, and others involved in the management and care of collections in museums and other cultural institutions.

Glacially triggered faulting describes movement of pre-existing faults caused by a combination of tectonic and glacially induced isostatic stresses. The most impressive fault-scarps are found in northern Europe, assumed to be reactivated at the end of the deglaciation. This view has been challenged as new faults have been discovered globally with advanced techniques such as LiDAR, and fault activity dating has shown several phases of reactivation thousands of years after deglaciation ended. This book summarizes the current state-of-the-art research in glacially triggered faulting, discussing the theoretical aspects that explain the presence of glacially induced structures and reviews the geological, geophysical, geodetic and geomorphological investigation methods. Written by a team of international experts, it provides the first global overview of confirmed and proposed glacially induced faults, and provides an outline for modelling these stresses and features. It is a go-to reference for geoscientists and engineers interested in ice sheet-solid Earth interaction.

In recent years, a number of disasters caused by earthquakes have demonstrated the vulnerability of both the developing and the developed world. This book provides new research on earthquakes. Chapter One focuses on the behavior of a simple spring-block model from the viewpoint of nonlinear dynamics and seismology. Chapter Two employs a new technique based on Extreme Learning Machine (ELM) for determination of liquefaction susceptibility of soil based on Standard Penetration Test (SPT) and Cone Penetration Test (CPT) from the Chi-Chi earthquake. Chapter Three presents a review of earthquake phenomenon in Nigeria, the occurrence and available data. Chapter Four describes the behavior and failure mechanisms of unreinforced masonry buildings and different rehabilitation and strengthening techniques. Chapter Five presents the results related to the preferred sources of information related to Risk, Hazard and Natural disaster. Chapter Six presents results regarding urban and semi-rural schoolchildren's seismic risk perception, awareness and preparedness of a highly seismic region, in the state of Oaxaca, Mexico. Chapter Seven reviews the anomalous decrease in groundwater radon before the Taiwan large earthquakes.

Elements of 3D Seismology, Third Edition is a thorough introduction to the acquisition, processing, and interpretation of 3D seismic data. This third edition is a major update of the second edition. Sections dealing with interpretation have been greatly revised in accordance with improved understanding and availability of data and software. Practice exercises have been added, as well as a 3D seismic survey predesign exercise. Discussions include: conceptual and historical foundations of modern reflection seismology; an overview of seismic wave phenomena in acoustic, elastic, and porous media; acquisition principles for land and marine seismic surveys; methods used to create 2D and 3D seismic images from field data; concepts of dip moveout, prestack migration, and depth migration; concepts and limitations of 3D seismic interpretation for structure, stratigraphy, and rock property estimation; and the interpretation role of attributes, impedance estimation, and AVO. This book is intended as a general text on reflection seismology, including wave propagation, data acquisition, processing, and interpretation, and it will be of interest to entry-level geophysicists, experts in related fields (geology, petroleum engineering), and experienced geophysicists in one subfield wishing to learn about another (e.g., interpreters wanting to learn about seismic waves or data acquisition).

This book is an introductory text to a range of numerical methods used today to simulate time-dependent processes in Earth science, physics, engineering, and many other fields. The physical problem of elastic wave propagation in 1D serves as a model system with which the various numerical methods are introduced and compared. The theoretical background is presented with substantial graphical material supporting the concepts. The results can be reproduced with the supplementary electronic material provided as python codes embedded in Jupyter notebooks. The book starts with a primer on the physics of elastic wave propagation, and a chapter on the fundamentals of parallel programming, computational grids, mesh generation, and hardware models. The core of the book is the presentation of numerical solutions of the wave equation with six different methods: 1) the finite-difference method; 2) the pseudospectral method (Fourier and Chebyshev); 3) the linear finite-element method; 4) the spectral-element method; 5) the finite-volume method; and 6) the discontinuous Galerkin method. Each chapter contains comprehension questions, theoretical, and programming exercises. The book closes with a discussion of domains of application and criteria for the choice of a specific numerical method, and the presentation of current challenges.

For months in early 1980, scientists, journalists and ordinary people listened anxiously to rumblings in the long quiescent volcano Mount St. Helens. Still, when a massive explosion took the top off the mountain, no one was prepared. Fifty-seven people died and the lives of many others were changed forever. Steve Olson interweaves history, science and vivid personal stories to portray the disaster as a multi-faceted turning point. Powerful economic, political and historical forces influenced who died when the volcano erupted. The eruption of Mount St. Helens transformed volcanic science, the study of environmental resilience and our perceptions of how to survive on an increasingly dangerous planet.

Improved Seismic Monitoring?Improved Decision-Making, describes and assesses the varied economic benefits potentially derived from modernizing and expanding seismic monitoring activities in the United States. These benefits include more effective loss avoidance regulations and strategies, improved understanding of earthquake processes, better engineering design, more effective hazard mitigation strategies, and improved emergency response and recovery. The economic principles that must be applied to determine potential benefits are reviewed and the report concludes that although there is insufficient information available at present to fully quantify all the potential benefits, the annual dollar costs for improved seismic monitoring are in the tens of millions and the potential annual dollar benefits are in the hundreds of millions.

Ash produced as a consequence of explosive volcanic eruptions can cause multiple hazards both close to the volcano and at great distances. Explosive volcano eruptions often release volcanic plumes into the atmosphere, which consist of tephra (submillimeter-sized rock particles), water vapor and other gases such as carbon dioxide (CO2), sulfur dioxide (SO2) and hydrogen sulfide (H2S). Particles from volcano eruptions are transported by wind to thousands of kilometers away, or even over 10,000 km from their source for some fine particles. This book discusses the environmental impact and health risks volcanic ash poses as well as its chemical composition.

Metamorphism generates electrical and magnetic phenomena, and is influenced by these forces. Information fundamental to their combined study is presented, including examples from microtectonics, crystal physics, geophysics, seismology, mineralogy and materials science. Applications for earthquake prediction, planetary science research, alternative energy and science education are included. Work on reported seismic electric signals is analyzed and summarized. Ten hypotheses related to earthquake mechanisms and prediction are presented, as well as eighteen recommendations for further study. Eight microtectonic deformation mechanisms are explored. Two hundred seventeen descriptions of minerals exhibiting ferroelectricity, pyroelectricity or piezoelectricity are presented, with quantitative data where known. Fifty-three of these are centrosymmetric, and explanations are given for their apparent violations of crystal theory. A comprehensive list of thirty-two mechanisms that generate telluric currents is also presented, as are some novel or inexpensive experimental techniques in crystal physics.
