Among all the numerical methods in seismology, the finite-difference (FD) technique provides the best balance of accuracy and computational efficiency. This book offers a comprehensive introduction to FD and its applications to earthquake motion. Using a systematic tutorial approach, the book requires only undergraduate degree-level mathematics and provides a user-friendly explanation of the relevant theory. It explains FD schemes for solving wave equations and elastodynamic equations of motion in heterogeneous media, and provides an introduction to the rheology of viscoelastic and elastoplastic media. It also presents an advanced FD time-domain method for efficient numerical simulations of earthquake ground motion in realistic complex models of local surface sedimentary structures. Accompanied by a suite of online resources to help put the theory into practice, this is a vital resource for professionals and academic researchers using numerical seismological techniques, and graduate students in earthquake seismology, computational and numerical modelling, and applied mathematics.

Our understanding of stars has grown significantly due to recent advances in asteroseismology, the stellar analog of helioseismology, the study of the Sun's acoustic wave oscillations. Using ground-based and satellite observatories to measure the frequency spectra of starlight, researchers are able to probe beneath a star's surface and map its interior structure. This volume provides a wide-ranging and up-to-date overview of the theoretical, experimental and analytical tools for carrying out front-line research in stellar physics using asteroseismological observations, tools and inferences. Chapters from seven eminent scientists in residence at the twenty-second Canary Islands Winter School of Astrophysics examine the interior of our Sun relative to data collected from distant stars, how to measure the fundamental parameters of single field stars, diffusion processes, and the effects of rotation on stellar structures. The volume also provides detailed treatments of modeling and computing programs, providing astronomers and graduate students a practical, methods-based guide.

What are the real risks posed by a volcanic eruption near a city - what is fact and what is myth? How have volcanic eruptions affected cities in the past, and how can we learn from these events? Why do communities continue to develop in such locations, despite the obvious threat? In this fascinating book, Grant Heiken explores global examples of cities at risk from volcanoes, from Italy, the US, Mexico, Ecuador, The Philippines, Japan and New Zealand, providing historical and contemporary eruption case studies to illustrate volcanic hazards, and cities' efforts to respond to them, both good and poor. He shows that truly successful volcanic hazard mitigation cannot be accomplished without collaboration between experts in geology and natural hazards, public health, medicine, city and infrastructure planning, and civil protection. This is a topical and engaging read for anyone interested in the history and future activity of these dangerous neighbors.

A fascinating look at extraterrestrial volcanoes in our Solar System. The volcano - among the most familiar and perhaps the most terrifying of all geological phenomena. However, Earth isn't the only planet to harbour volcanoes. In fact, the Solar System, and probably the entire Universe, is littered with them. Our own Moon, which is now a dormant piece of rock, had lava flowing across its surface billions of years ago, while Mars can be credited with the largest volcano in the Solar System, Olympus Mons, which stands 25km high. While Mars's volcanoes are long dead, volcanic activity continues in almost every other corner of the Solar System, in the most unexpected of locations. We tend to think of Earth volcanoes as erupting hot, molten lava and emitting huge, billowing clouds of incandescent ash. However, it isn't necessarily the same across the rest of the Solar System. For a start, some volcanoes aren't even particularly hot. Those on Pluto, for example, erupt an icy slush of substances such as water, methane, nitrogen or ammonia, that freeze to form ice mountains as hard as rock. While others, like the volcanoes on one of Jupiter's moons, Io, erupt the hottest lavas in the Solar System onto a surface covered in a frosty coating of sulphur. Whether they are formed of fire or ice, volcanoes are of huge importance for scientists trying to picture the inner workings of a planet or moon. Volcanoes dredge up materials from the otherwise inaccessible depths and helpfully deliver them to the surface. The way in which they erupt, and the products they generate, can even help scientists ponder bigger questions on the possibility of life elsewhere in the Solar System. Fire and Ice is an exploration of the Solar System's volcanoes, from the highest peaks of Mars to the intensely inhospitable surface of Venus and the red-hot summits of Io, to the coldest, seemingly dormant icy carapaces of Enceladus and Europa, an unusual look at how these cosmic features are made, and whether such active planetary systems might host life.

Annals of natural disasters have always caused common interest. Scientists and specialists of various domains, teachers, students, post-graduates, journalists .. and merely inquisitive can find useful and didactic information in such annals~ Sad experience of the natural disasters endured gives very important material for humanity. It allows us not only to understand better the phenomenon itself, but also to prepare ourselves for future cataclysms, which our "Mother-Nature" is so rich in. The book by Sergey Soloviev and a group of his collaborators represents a detailed description of tsunami waves and accompanying phenomena in the Mediterranean Sea over a period of approximately four thousand years. Sergey Soloviev, the founder and recognised leader of the Russian scientific school of tsunami researchers, was unable to see the publication of this book, passing away on March 9, 1994. However, his ample experience in investigation and systematisation of tsunami waves for the Pacific area [Soloviev and Go, 1974, 1975; Soloviev, Go and Kim, 1986] has been widely used in compiling this book. The Mediterranean coasts are the cradle of civilisation. Written accounts of past disasters in this region of the Earth are rather numerous and highly reliable. Therefore the results of the tsunami study in the Mediterranean Sea are of specific value both for the scientific community and for humanity at large.

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.

From prehistoric times to the fiery destruction of Pompeii in 79 A.D. and the more recent pyrotechnics of Mt. St. Helens, volcanic eruptions have aroused fear, inspired myths and religious worship, and prompted heated philosophical and scientific debate. Melting the Earth chronicles humankind's attempt to understand this terrifying phenomenon and provides a fascinating look at how our conception of volcanoes has changed as knowledge of the earth's internal processes has deepened over the centuries.
A practicing volcanologist and native of Iceland, where volcanoes are frequently active, Haraldur Sigurdsson considers how philosophers and scientists have attempted to answer the question: Why do volcanoes erupt? He takes us through the ideas of the ancient Greeks--who proposed that volcanoes resulted from the venting of subterranean winds--and the internal combustion theories of Roman times, and notes how thinking about volcanoes took a backward, symbolic turn with the rise of Christian conceptions of Hell, a direction that would not be reversed until the Renaissance. He chronicles the 18th-century conflict between the Neptunists, who believed that volcanic rocks originated from oceanic accretions, and the Plutonists, who argued for the existence of a molten planetary core, and traces how volcanology moved from "divine science" and "armchair geology" to empirical field study with the rise of 19th-century naturalism. Finally, Sigurdsson describes how 19th and 20th-century research in thermodynamics, petrology, geochemistry and plate tectonics contribute to the current understanding of volcanic activity.
Drawing liberally from classical sources and firsthand accounts, this chronicle is not only a colorful history of volcanology, but an engrossing chapter in the development of scientific thought.

Volcanoes are some of the most dramatic expressions of the powerful tectonic forces at work in the Earth beneath our feet. But volcanism, a profoundly important feature of Earth, and indeed of other planets and moons too, encompasses much more than just volcanoes themselves. On a planetary scale, volcanism is an indispensable heat release mechanism, which on Earth allows the conditions for life. IIt releases gases into the atmosphere and produces enormous volumes of rock, and spectacular landscapes - landscapes which, during major eruptions, can be completely reshaped in a matter of hours. Through geological time volcanism has shaped both climate and biological evolution, and volcanoes can affect human life, too, for both good and ill. Yet, even after much study, some of the fundamental aspects of volcanicity remain mysterious. This Very Short Introduction takes the readers into the inferno of a racing pyroclastic current, and the heart of a moving lava flow, as understood through the latest scientific research. Exploring how volcanologists forensically decipher how volcanoes work, Michael Branney and Jan Zalasiewicz explain what we do (and don't) understood about the fundamental mechanisms of volcanism, and consider how volcanoes interact with other physical processes on the Earth, with life, and with human society. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

While a student, George Poulett Scrope (1797 1876) visited Vesuvius and Etna and developed a passionate enthusiasm for volcanos. He did pioneering fieldwork in France in 1821, witnessed the eruption of Vesuvius in 1822, and was elected a Fellow of the Royal Society in 1826. Scrope became increasingly involved in economics and politics, but later in his career published revised versions of two pioneering books on volcanism he had originally published in the 1820s. Volcanos (1862), reissued here, was based on his Considerations on Volcanos (1825, also reissued in this series) and dedicated to his life-long friend and colleague Charles Lyell. This influential work on volcanic phenomena includes a substantial catalogue of 'all known volcanos and volcanic formations' as well as a dramatic illustration of Vesuvius. It was translated into French and German, went into a second English edition in 1872, and was one of the foundational texts of volcanology.

John Milne (1850 1913) was a professor of mining and geology at the Imperial College of Engineering, Tokyo. While living in Japan, Milne became very interested in seismology, prompted by a strong seismic shock he experienced in Tokyo in 1880. Sixteen years later Milne and two colleagues completed work on the first seismograph capable of recording major earthquakes. This book, originally published in London in 1886, explains why earthquakes happen and what effects they have on land and in the oceans. As Milne points out, Japan provided him with 'the opportunity of recording an earthquake every week'. Starting with an introduction examining the relationship of seismology to the arts and sciences, the book includes chapters on seismometry, earthquake motion, the causes of earthquakes, and their relation to volcanic activity, providing a thorough account of the state of knowledge about these phenomena towards the end of the nineteenth century.

Charles Daubeny (1795 1867) first published Active and Extinct Volcanos in 1826. This reissue is of the second, augmented edition of 1848, which the author explains was significantly updated in the light of the work of Charles Darwin. Part I contains geological descriptions of most of the world's known volcanos, arranged by region, many of them based on Daubeny's own observations. Part II contains descriptions of earthquake-prone regions, thermal springs, and thermal waters. In Part III Daubeny introduces his influential theory of the causes of volcanic action, proposing that it results from contact between water and metals beneath the earth's surface. He also discusses the factors that give volcanos particular characteristics, and the impact of volcanos on their environments. This pioneering work of Victorian geology provided the scientific community with some of the first descriptions and data sets on previously unstudied volcanic regions, and is still referred to today.

This book is the third volume of three volume series recording the "Radon Special Semester 2011 on Multiscale Simulation & Analysis in Energy and the Environment" taking place in Linz, Austria, October 3-7, 2011. This book surveys recent developments in the analysis of wave propagation problems. The topics covered include aspects of the forward problem and problems in inverse problems, as well as applications in the earth sciences. Wave propagation problems are ubiquitous in environmental applications such as seismic analysis, acoustic and electromagnetic scattering. The design of efficient numerical methods for the forward problem, in which the scattered field is computed from known geometric configurations is very challenging due to the multiscale nature of the problems. Even more challenging are inverse problems where material parameters and configurations have to be determined from measurements in conjunction with the forward problem. This book contains review articles covering several state-of-the-art numerical methods for both forward and inverse problems. This collection of survey articles focusses on the efficient computation of wave propagation and scattering is a core problem in numerical mathematics, which is currently of great research interest and is central to many applications in energy and the environment. Two generic applications which resonate strongly with the central aims of the Radon Special Semester 2011 are forward wave propagation in heterogeneous media and seismic inversion for subsurface imaging. As an example of the first application, modelling of absorption and scattering of radiation by clouds, aerosol and precipitation is used as a tool for interpretation of (e.g.) solar, infrared and radar measurements, and as a component in larger weather/climate prediction models in numerical weather forecasting. As an example of the second application, inverse problems in wave propagation in heterogeneous media arise in the problem of imaging the subsurface below land or marine deposits. The book records the achievements of Workshop 3 "Wave Propagation and Scattering, Inverse Problems and Applications in Energy and the Environment". It brings together key numerical mathematicians whose interest is in the analysis and computation of wave propagation and scattering problems, and in inverse problems, together with practitioners from engineering and industry whose interest is in the applications of these core problems.

This book interprets Robert Hooke's Lectures and Discourses of Earthquakes, and Subterraneous Eruptions (1667-1694). Hooke's hypotheses concerning the origin of terrestrial features were of major importance to the development of geology. The volume consists of the original text of the Discourses transposed into modern type and paired with explanatory annotations; a brief up-to-date biography of Hooke, with emphasis on his geological contributions; and a comparison of selected passages from James Hutton, to show the transmission of ideas and Hooke's influence on later geologists.

This book examines historical evidence from the last 2000 years to analyse earthquakes in the eastern Mediterranean and Middle East. Early chapters review techniques of historical seismology, while the main body of the book comprises a catalogue of more than 4000 earthquakes identified from historical sources. Each event is supported by textual evidence extracted from primary sources and translated into English. Covering southern Rumania, Greece, Turkey, Lebanon, Israel, Egypt, Jordan, Syria, and Iraq, the book documents past seismic events, places them in a broad tectonic framework, and provides essential information for those attempting to prepare for, and mitigate the effects of, future earthquakes and tsunamis in these countries. This volume is an indispensable reference for researchers studying the seismic history of the eastern Mediterranean and Middle East, including archaeologists, historians, earth scientists, engineers and earthquake hazard analysts. A parametric catalogue of these seismic events can be downloaded from www.cambridge.org/9780521872928.

An Introduction to Seismology, Earthquakes and Earth Structures is an introduction to seismology and its role in the earth sciences, and is written for advanced undergraduate and beginning graduate students.

The fundamentals of seismic wave propagation are developed using a physical approach and then applied to show how refraction, reflection, and teleseismic techniques are used to study the structure and thus the composition and evolution of the earth. The book shows how seismic waves are used to study earthquakes and are integrated with other data to investigate the plate tectonic processes that cause earthquakes. Figures, examples, problems, and computer exercises teach students about seismology in a creative and intuitive manner. Necessary mathematical tools including vector and tensor analysis, matrix algebra, Fourier analysis, statistics of errors, signal processing, and data inversion are introduced with many relevant examples. The text also addresses the fundamentals of seismometry and applications of seismology to societal issues. Special attention is paid to help students visualize connections between different topics and view seismology as an integrated science.

Magmatic sulfides provide most of the world's supplies of platinum and nickel, among other rare and valuable ores. The author, a ranking authority on the topic, discusses the types of rocks that contain magmatic sulfides, the chemical processes by which they form, and the geological setting of major nickel-copper and platinum deposits throughout the world--in Canada, Australia, the U.S.S.R., South Africa, the U.S.A., and Zimbabwe. Naldrett also examines how theories about ore genesis can be applied in exploring for minerals. The book will be used in graduate-level courses and by economic geologists, geochemists, and geologists in the mining industry. It will also be of interest to members of geological surveys worldwide.

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.

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.

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.
