Modern seismology is a relatively new science; most current ideas originated no earlier than the latter half of the nineteenth century. The focus of this book is on seismological concepts, how they originated and how they form our modern understanding of the science. A history of seismology falls naturally into four periods: a largely mythological period previous to the 1755 Lisbon earthquake; a period of direct observation from then to the development of seismometers in the late 19th century; a period during which study of seismic arrival times were used to outline the structure of the earth's interior extending to the 1960s; the modern era in which all aspects of seismic waves are used in combination with trial models and computers to elucidate details of the earthquake process. This history attempts to show how modern ideas grew from simple beginnings. Ideas are rarely new, and their first presentations are often neglected until someone is able to present the evidence for their correctness convincingly. Much care has been used to give the earliest sources of ideas and to reference the basic papers on all aspects of earthquake seismology to help investigators find such references in tracing the roots of their own work.

Kostrov and Das present a general theoretical model summarizing our current knowledge of fracture mechanics as applied to earthquakes and earthquake source processes. Part I explains continuum and fracture mechanics, providing the reader with some background and context. Part II continues with a discussion of the inverse problem of earthquake source theory and a description of the seismic moment tensor. Part III presents specific earthquake source models. Although data processing and acquisition techniques are discussed only in simplified form for illustrative purposes, the material in this book will aid in better orienting and developing these techniques. The aim of this book is to explore the phenomena underlying earthquake fracture and present a general theoretical model for earthquake source processes.

"Earthquake and Volcano Deformation" is the first textbook to present the mechanical models of earthquake and volcanic processes, emphasizing earth-surface deformations that can be compared with observations from Global Positioning System (GPS) receivers, Interferometric Radar (InSAR), and borehole strain- and tiltmeters. Paul Segall provides the physical and mathematical fundamentals for the models used to interpret deformation measurements near active faults and volcanic centers.

Segall highlights analytical methods of continuum mechanics applied to problems of active crustal deformation. Topics include elastic dislocation theory in homogeneous and layered half-spaces, crack models of faults and planar intrusions, elastic fields due to pressurized spherical and ellipsoidal magma chambers, time-dependent deformation resulting from faulting in an elastic layer overlying a viscoelastic half-space and related earthquake cycle models, poroelastic effects due to faulting and magma chamber inflation in a fluid-saturated crust, and the effects of gravity on deformation. He also explains changes in the gravitational field due to faulting and magmatic intrusion, effects of irregular surface topography and earth curvature, and modern concepts in rate- and state-dependent fault friction. This textbook presents sample calculations and compares model predictions against field data from seismic and volcanic settings from around the world.

"Earthquake and Volcano Deformation" requires working knowledge of stress and strain, and advanced calculus. It is appropriate for advanced undergraduates and graduate students in geophysics, geology, and engineering.

Fundamentals of Seismic Wave Propagation, published in 2004, presents a comprehensive introduction to the propagation of high-frequency body-waves in elastodynamics. The theory of seismic wave propagation in acoustic, elastic and anisotropic media is developed to allow seismic waves to be modelled in complex, realistic three-dimensional Earth models. This book provides a consistent and thorough development of modelling methods widely used in elastic wave propagation ranging from the whole Earth, through regional and crustal seismology, exploration seismics to borehole seismics, sonics and ultrasonics. Particular emphasis is placed on developing a consistent notation and approach throughout, which highlights similarities and allows more complicated methods and extensions to be developed without difficulty. This book is intended as a text for graduate courses in theoretical seismology, and as a reference for all academic and industrial seismologists using numerical modelling methods. Exercises and suggestions for further reading are included in each chapter.

This is the first book to really make sense of the dizzying array of information that has emerged in recent decades about earthquakes. Susan Hough, a research seismologist in one of North America's most active earthquake zones and an expert at communicating this complex science to the public, separates fact from fiction. She fills in many of the blanks that remained after plate tectonics theory, in the 1960s, first gave us a rough idea of just what earthquakes are about. How do earthquakes start? How do they stop? Do earthquakes occur at regular intervals on faults? If not, why not? Are earthquakes predictable? How hard will the ground shake following an earthquake of a given magnitude? How does one quantify future seismic hazard?

As Hough recounts in brisk, jargon-free prose, improvements in earthquake recording capability in the 1960s and 1970s set the stage for a period of rapid development in earthquake science. Although some formidable enigmas have remained, much has been learned on critical issues such as earthquake prediction, seismic hazard assessment, and ground motion prediction. This book addresses those issues.

Because earthquake science is so new, it has rarely been presented outside of technical journals that are all but opaque to nonspecialists. "Earthshaking Science" changes all this. It tackles the issues at the forefront of modern seismology in a way most readers can understand. In it, an expert conveys not only the facts, but the passion and excitement associated with research at the frontiers of this fascinating field. Hough proves, beyond a doubt, that this passion and excitement is more accessible than one might think.

Bridging the gap between introductory textbooks and advanced monographs, this book provides the necessary mathematical tools to tackle seismological problems and demonstrates how to apply them. Including student exercises, for which solutions are available on a dedicated website, it appeals to advanced undergraduate and graduate students. It is also a useful reference volume for researchers wishing to "brush up" on fundamentals before they study more advanced topics in seismology.

The two volumes of The Seismic Wavefield are a comprehensive guide to the understanding of seismograms in terms of physical propagation processes within the Earth. The focus is on the observation of earthquakes and man-made sources on all scales, for both body waves and surface waves. Volume I provides a general introduction and a development of the theoretical background for seismic waves. Volume II looks at the way in which observed seismograms relate to the propagation processes. Volume II also discusses local and regional seismic events, global wave propagation, and the three-dimensional Earth.

The Seismic Wavefield provides a guide to the understanding of seismograms in terms of physical propagation processes within the Earth. The focus is on the observation of earthquakes and man-made sources on all scales, for both body waves and surface waves. Volume I begins with a survey of the structure of the Earth and the nature of seismic wave propagation using examples of observed seismograms. The second part provides a full development of the theoretical background for seismic waves. Volume II (to be published later) will cover local and regional seismic events, global wave propagation, and the three-dimensional earth.

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.

The theory of plate tectonics transformed earth science. The hypothesis that the earth's outermost layers consist of mostly rigid plates that move over an inner surface helped describe the growth of new seafloor, confirm continental drift, and explain why earthquakes and volcanoes occur in some places and not others. Lynn R. Sykes played a key role in the birth of plate tectonics, conducting revelatory research on earthquakes. In this book, he gives an invaluable insider's perspective on the theory's development and its implications. Sykes combines lucid explanation of how plate tectonics revolutionized geology with unparalleled personal reflections. He entered the field when it was on the cusp of radical discoveries. Studying the distribution and mechanisms of earthquakes, Sykes pioneered the identification of seismic gaps-regions that have not ruptured in great earthquakes for a long time-and methods to estimate the possibility of quake recurrence. He recounts the various phases of his career, including his antinuclear activism, and the stories of colleagues around the world who took part in changing the paradigm. Sykes delves into the controversies over earthquake prediction and their importance, especially in the wake of the giant 2011 Japanese earthquake and the accompanying Fukushima disaster. He highlights geology's lessons for nuclear safety, explaining why historic earthquake patterns are crucial to understanding the risks to power plants. Plate Tectonics and Great Earthquakes is the story of a scientist witnessing a revolution and playing an essential role in making it.

The length of Aegean arc in south-west Turkey has been deter mined by the use of intermediate focal depth earthquakes which occurred between 1900-1985 in the south-west of Turkey (34.00- 38.00 Nand 27.00-32.00 E). Intermediate focal depth earthqua kes in south-west Turkey revealed the presence of a seismic Benioff zone caused by underthrusting of the African litho spheric plate by the Aegean arc. In order to determine the geometry of underthrustin%detailed epicenter maps of the in termediate depth earthquakes in south-west of Turkey were pre pared. It is known that these earthquakes brought great harm in the past. Investigation of time distribution of them will help to predict the occurrence of them in the future. These intermediate focal depth earthquakes can be differenti ated from deep ones by their micro- and macroseismic proper ties. Papazachos (1969) and Comninakis (1970) found that the foci of these earthquakes are in a zone underthrusting exten ding from the East Mediterranean to the Aegean arc. Morgan (1968) and Le pichori (1968) defined three plates which are important in East Mediterranean tectonics. These are the Afri ca, Arabic and Eurasian plates. They define wide earthquake belt on the boundaries between the African and Eurasian plate."

Volcanoes of North America capitalises on the vast body of volcano literature now available to present, in a single source, detailed information about volcanoes found in North America. It contains brief accounts, written by leading experts in volcanology, of over 250 volcanoes and volcanic fields formed during the last 5 million years. The volcanoes of the continental United States, Alaska, Hawaii, and Canada are described. The precise location of each volcano is given, and the volcano is classified by type. Information about composition and eruptive history is also included. Each narrative description is accompanied by a photograph, a map of each location, and an extremely helpful statement on how to reach each volcano. The entries are mostly written at a level understandable by lay readers, but technical terms are also used and a background in geology is advantageous. Volcanoes of North America will be a standard reference work for practising volcanologists, petrologists, and geochemists, and to some extent, geographers. In addition, the maps and the 'How to get there' sections make this a highly valuable book for anyone interested in natural history or fascinated by volcanoes.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 160.Understanding the inner workings of our planet and its relationship to processes closer to the surface remains a frontier in the geosciences. Manmade probes barely reach 10 km depth and volcanism rarely brings up samples from deeper than 150 km. These distances are dwarfed by Earth's dimensions, and our knowledge of the deeper realms is pieced together from a range of surface observables, meteorite and solar atmosphere analyses, experimental and theoretical mineral physics and rock mechanics, and computer simulations. A major unresolved issue concerns the nature of mantle convection, the slow (1-5 cm/year) solid-state stirring that helps cool the planet by transporting radiogenic and primordial heat from Earth's interior to its surface.

Expanding our knowledge here requires input from a range of geoscience disciplines, including seismology, geodynamics, mineral physics, and mantle petrology and chemistry. At the same time, with better data sets and faster computers, seismologists are producing more detailed models of 3-D variations in the propagation speed of different types of seismic waves; new instrumentation and access to state-of-the-art community facilities such as synchrotrons have enabled mineral physicists to measure rock and mineral properties at ever larger pressures and temperatures; new generations of mass spectrometers are allowing geo-chemists to quantify minute concentrations of diagnostic isotopes; and with supercomputers geodynamicists are making increasingly realistic simulations of dynamic processes at conditions not attainable in analogue experiments. But many questions persist. What causes the lateral variations in seismic wavespeed that we can image with mounting accuracy? How reliable are extrapolations of laboratory measurements on simple materials over many orders of magnitude of pressure and temperature? What are the effects of volatiles and minor elements on rock and mineral properties under extreme physical conditions? Can ab initio calculations help us understand material behavior in conditions that are still out of reach of laboratory measurement? What was the early evolution of our planet and to what extent does it still influence present-day dynamics? And how well do we know such first-order issues as the average bulk composition of Earth?

Geopressure, or pore pressure in subsurface rock formations impacts hydrocarbon resource estimation, drilling, and drilling safety in operations. This book provides a comprehensive overview of geopressure analysis bringing together rock physics, seismic technology, quantitative basin modeling and geomechanics. It provides a fundamental physical and geological basis for understanding geopressure by explaining the coupled mechanical and thermal processes. It also brings together state-of-the-art tools and technologies for analysis and detection of geopressure, along with the associated uncertainty. Prediction and detection of shallow geohazards and gas hydrates is also discussed and field examples are used to illustrate how models can be practically applied. With supplementary MATLAB (R) codes and exercises available online, this is an ideal resource for students, researchers and industry professionals in geoscience and petroleum engineering looking to understand and analyse subsurface formation pressure.

Geologically Active contains over 500 papers from 44 countries worldwide, which were presented at the 11th Congress of the IAEG, and includes the state-of-the-art on practise in engineering geology. Engineering geology now extends into a host of linked fields: disaster risk management and climate change, preservation of lifelines, geophysics, interpretation of satellite imagery, communication, instrumentation, mining, tunnelling, groundwater, rehabilitation and brown-field development, wine, recyclable materials, ethics, and education. Communication with non-specialists and developing green solutions has never been more important and the industry is evolving tools and emerging ideas to more appropriately achieve this.

This volume brings together engineering, science and practice to focus on the very real effects of active geological processes on communities and infrastructure and their development. The theme of Geologically Active is developed through five chapters focussing on assessment and identification of natural hazards, the meeting of geological phenomena with people and infrastructure to create risk, approaches to hazard mitigation around the world, application of engineering geological techniques and practice, site investigation and geotechnical modelling, and engineering geology in the global economy, bridging the gap between scientists, engineers and non-practitioners in a changing world environment. Geologically Active encourages the transformation of science research into practice, offering a connection between scientific progress and community resilience, and will be invaluable to engineering and geological academics and consultants, government organizations, and power and mining companies.

Whenever a volcano threatens to erupt, scientists and adventurers from around the world flock to the site in response to the irresistible allure of one of nature's most dangerous and unpredictable phenomena. In a unique book probing the science and mystery of these fiery features, the authors chronicle not only their geologic behavior but also their profound effect on human life. From Mount Vesuvius to Mount St. Helens, the book covers the surprisingly large variety of volcanoes, the subtle to conspicuous signs preceding their eruptions, and their far-reaching atmospheric consequences. Here scientific facts take on a very human dimension, as the authors draw upon actual encounters with volcanoes, often through firsthand accounts of those who have witnessed eruptions and miraculously survived the aftermath.

The book begins with a description of the lethal May 1980 eruption of Mount St. Helens--complete with an explanation of how safety officials and scientists tried to predict events, and how unsuspecting campers and loggers miles away struggled against terrifying blasts of ash, stone, and heat. The story moves quickly to the ways volcanoes have enhanced our lives, creating mineral-rich land, clean thermal energy, and haunting landscapes that in turn benefit agriculture, recreation, mining, and commerce. Religion and psychology embroider the account, as the authors explore the impact of volcanoes on the human psyche through tales of the capricious volcano gods and attempts to appease them, ranging from simple homage to horrific ritual sacrifice.

"Volcanoes" concludes by assisting readers in experiencing these geological phenomena for themselves. An unprecedented "tourist guide to volcanoes" outlines over forty sites throughout the world. Not only will travelers find information on where to go and how to get there, they will also learn what precautions to take at each volcano. Tourists, amateur naturalists, and armchair travelers alike will find their scientific curiosity whetted by this informative and entertaining book.
