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.

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 ray method plays an important role in seismology, seismic exploration, and in the interpretation of seismic measurements. Seismic Ray Theory presents the most comprehensive treatment of the method available. Many new concepts that extend the possibilities and increase the method's efficiency are included. The book has a tutorial character: derivations start with a relatively simple problem, in which the main ideas are easier to explain, and then advance to more complex problems. Most of the derived equations are expressed in algorithmic form and may be used directly for computer programming. This book will prove to be an invaluable advanced text and reference in all academic institutions in which seismology is taught or researched.

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.

Describes the basic structure, concepts, and application of deterministic and probabilistic seismic hazard analysis from a perspective useful to earth scientists, engineers, and decision-makers dealing with hazard evaluation. Draws on Reiter's long experience with government agencies concerned with

Seismic amplitudes yield key information on lithology and fluid fill, enabling interpretation of reservoir quality and likelihood of hydrocarbon presence. The modern seismic interpreter must be able to deploy a range of sophisticated geophysical techniques, such as seismic inversion, AVO (amplitude variation with offset), and rock physics modelling, as well as integrating information from other geophysical techniques and well data. This accessible, authoritative book provides a complete framework for seismic amplitude interpretation and analysis in a practical manner that allows easy application - independent of any commercial software products. Deriving from the authors' extensive industry expertise and experience of delivering practical courses on the subject, it guides the interpreter through each step, introducing techniques with practical observations and helping to evaluate interpretation confidence. Seismic Amplitude is an invaluable day-to-day tool for graduate students and industry professionals in geology, geophysics, petrophysics, reservoir engineering, and all subsurface disciplines making regular use of seismic data.

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?

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.

Its multidisciplinary content is relevant to a broad audience: structural geologist, experimentalists, rocks mechanicians, seismologist, geophysicists and modelers.

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.
