After every major earthquake, the Earth rings like a bell for several days. These free oscillations of the Earth and the related propagating body and surface waves are routinely detected at broad-band seismographic stations around the world. In this book, F. A. Dahlen and Jeroen Tromp present an advanced theoretical treatment of global seismology, describing the normal-mode, body-wave, and surface-wave methods employed in the determination of the Earth's three-dimensional internal structure and the source mechanisms of earthquakes. The authors provide a survey of both the history of global seismological research and the major theoretical and observational advances made in the past decade.

The book is divided into three parts. In the first, "Foundations," Dahlen and Tromp give an extensive introduction to continuum mechanics and discuss the representation of seismic sources and the free oscillations of a completely general Earth model. The resulting theory should provide the basis for future scientific discussions of the elastic-gravitational deformation of the Earth. The second part, "The Spherical Earth," is devoted to the free oscillations of a spherically symmetric Earth. In the third part, "The Aspherical Earth," the authors discuss methods of dealing with the Earth's three-dimensional heterogeneity. The book is concerned primarily with the forward problem of global seismology--detailing how synthetic seismograms and spectra may be calculated and interpreted.

As a long-needed unification of theories in global seismology, the book will be important to graduate students and to professional seismologists, geodynamicists, and geomagnetists, as well as to astronomers who study the free oscillations of the Sun and other stars.

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.

Volcanoes are unquestionably one of the most spectacular and awe-inspiring features of the physical world. Our paradoxical fascination with them stems from their majestic beauty and powerful, sometimes deadly, destructiveness. Notwithstanding the tremendous advances in volcanology since ancient times, some of the mystery surrounding volcanic eruptions remains today. The Encyclopedia of Volcanoes summarizes our present knowledge of volcanoes; it provides a comprehensive source of information on the causes of volcanic eruptions and both the destructive and beneficial effects. The early chapters focus on the science of volcanism (melting of source rocks, ascent of magma, eruption processes, extraterrestrial volcanism, etc.). Later chapters discuss human interface with volcanoes, including the history of volcanology, geothermal energy resources, interaction with the oceans and atmosphere, health aspects of volcanism, mitigation of volcanic disasters, post-eruption ecology, and the impact of eruptions on organismal biodiversity.

"If ever there was a subject crying out for a good biography it is Charles Richter, whose name we hear all too often on the news, a tocsin of catastrophe. If ever there was the ideal person to write his story it is Susan Hough, the seismologist who has so successfully made her mission the intelligent popularization of her calling. The combination of subject and writer is peerless-this is a quite wonderful story, impeccably told. If ever there was to be a Richter scale for biography, this surely merits a 9.5, at the very least."--Simon Winchester, author of "A Crack in the Edge of the World: America and the Great California Earthquake of 1906"

"Sue Hough brings Charlie Richter to life and, with him, the founders of seismology in southern California. More than simply the inventor of the magnitude scale, Richter was a brilliant, if troubled, scientist and a poet who might have suffered from Asperger's syndrome. Hough shows how this 'accidental seismologist' (his Ph.D. was in theoretical physics) influenced the evolving field of earthquake science and the public perception of earthquake hazard and risk in California and the world."--Robert S. Yeats, author of "Living with Earthquakes in California"

"The story of Charles Richter is a fascinating, albeit somewhat disquieting, one. Susan Hough has done a remarkable job of research, and her writing style makes this a very appealing read."--Clarence Allen, Professor of Geology and Geophysics, Emeritus, California Institute of Technology

""Richter's Scale" is the first biography of the world's most famous seismologist. It tells a story well worth reading and full of surprises. The book provides a remarkable perspective on how the careerof an important scientist can develop in a way that is quite far from a straight-line process. At the same time, it presents a compelling and rather sad story of the personal struggles of the man behind the Richter scale."--Clifford H. Thurber, University of Wisconsin, Madison

"This is an extraordinary piece of scientific biography. Although Charles Richter's name is a household word, even earth scientists know little about the man. This first biography of Richter gives a thoughtful and insightful view of the man, his science, and his crucial role in developing seismology, public awareness of earthquakes in southern California, and policies to reduce earthquake hazards through safer construction. It will be of great interest at a time when natural disaster mitigation is very much in public consciousness."--Seth Stein, Northwestern University

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.

Seismosaurus: The Earth Shaker is a richly illustrated telling of the trials and triumphs of the discovery and excavation of Seismosaurus hallorum, the longest dinosaur yet known - and possibly the largest land animal ever to have lived. This is the first book to explain clearly the science used by paleontologists and the new cutting-edge techniques that led to Seismosaurus's discovery. David Gillette's first-person account of the project answers the most frequently asked questions about Seismosaurus: How was it discovered? How do we know it is a new species? How was it named? And more intriguing still, how did it die? His chronicle also examines the sauropods in general - the giant dinosaurs that with Seismosaurus include Apatosaurus (Brontosaurus), Brachiosaurus, and Diplodocus. This lively tale of discovery is woven with anecdotes and descriptions of the details of the excavation, which began with small jackhammers and later incorporated such sophisticated machinery as ground-penetrating radar that "looks" for fossils underground with radio waves. The story moves from the excavation site in 1985 to current advances in research and then back to the prehistoric age as Gillette, in adventure-narrative style, describes the habitat, habits, and characteristics of the sauropod, right down to Seismosaurus's gastroliths - stomach stones that helped in digestion. Part catalogue of the workings of paleontological science in the 1990s, the book also illustrates the exciting collaboration between David Gillette and the chemists and physicists who helped to reconstruct Seismosaurus and its life. Excavation of the Seismosaurus skeleton was completed in the fall of 1993. Some bones are already ondisplay at the New Mexico Museum of Natural History. Meanwhile, Mark Hallett, a consultant on Steven Spielberg's Jurassic Park, brings Seismosaurus to life in more than eighty marvelous color and black-and-white illustrations. Seismosaurus: The Earth Shaker is a delight!

Twenty thousand years ago our planet was an icehouse. Temperatures were down six degrees; ice sheets kilometres thick buried much of Europe and North America and sea levels were 130m lower. The following 15 millennia saw an astonishing transformation as our planet metamorphosed into the temperate world upon which our civilisation has grown and thrived. One of the most dynamic periods in Earth history saw rocketing temperatures melt the great ice sheets like butter on a hot summer's day; feeding torrents of freshwater into ocean basins that rapidly filled to present levels. The removal of the enormous weight of ice at high latitudes caused the crust to bounce back triggering earthquakes in Europe and North America and provoking an unprecedented volcanic outburst in Iceland. A giant submarine landslide off the coast of Norway sent a tsunami crashing onto the Scottish coast while around the margins of the continents the massive load exerted on the crust by soaring sea levels encouraged a widespread seismic and volcanic rejoinder. In many ways, this post-glacial world mirrors that projected to arise as a consequence of unmitigated climate change driven by human activities. Already there are signs that the effects of climbing global temperatures are causing the sleeping giant to stir once again. Could it be that we are on track to bequeath to our children and their children not only a far hotter world, but also a more geologically fractious one?

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

"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.

The volcanic eruption of Santorini was the greatest in historical times. Assigned to the Late Minoan IA period, archaeological correlations implied a date late in the 16th century BC. Yet indirect natural science evidence suggested a date in the 17th century. The dating ceased to be indirect when branches of olive trees were found buried in the debris of the eruption. The radiocarbon Accelerator Mass Spectrometry (AMS) dating technique and the intcal04 calibration curve suggested a two-sigma range date between 1600 and 1627 BC. The debate continues; the papers here cover the radiocarbon results, the ice cores, the geology, and the archaeology, offering in-depth access to a controversy linking the natural sciences and the humanities. Aside from volcanologists, it will interest scholars of Bronze Age Aegean archaeology, the chronology of the eastern Mediterranean in the second millennium BC, archaeological methodology, the principles of radiocarbon dating and its application to Bronze Age sources.

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.

This Italian work, published in Naples in 1897, provides a comprehensive bibliography of works, published in Europe and the United States prior to the twentieth century, on the subject of Mount Vesuvius. Federigo Furchheim (b. 1844) begins with the famous eruption of 1631, on the ground that ancient accounts are sufficiently well known, and that reports and descriptions before the seventeenth century are not reliable. The bibliography is wide-ranging and includes works on other volcanos (such as Santorini), earthquakes and mineralogy. Nor is it confined to factual observations: travel writing, poetry, and even fiction, including Bulwer Lytton's The Last Days of Pompeii, appear alongside scientists such as Sir Humphry Davy and enthusiastic amateurs such as Sir William Hamilton. The book includes a chronological listing of published maps and illustrations, and an appendix, arranged chronologically and by topic, that briefly lists ancient and medieval accounts as well as more modern publications.

Mount Etna in Sicily is one of a small number of active volcanoes in the Mediterranean area, where written history survives from more than two millennia: its eruptions are therefore among the best documented in the world. This account of the eruption of 1819 was written by the chemist and vulcanologist Carmelo Maravigna, a professor at the University of Catania, who was commissioned by his colleagues to make scientific observations of the phenomena and to publish them in a clear and methodical format. Maravigna's book opens with the diary of his own observations from 27 May to 5 August 1819; it then describes the physical consequences of the eruption, including the spread and depth of lava flows, and discusses various theories of volcanic activity. The sixth chapter analyses the mineral deposits in the lava, and the last describes the volcano returned to its dormant state.

The most utilized technique for exploring the Earth's subsurface for petroleum is reflection seismology. However, a sole focus on reflection seismology often misses opportunities to integrate other geophysical techniques such as gravity, magnetic, resistivity, and other seismicity techniques, which have tended to be used in isolation and by specialist teams. There is now growing appreciation that these technologies used in combination with reflection seismology can produce more accurate images of the subsurface. This book describes how these different field techniques can be used individually and in combination with each other and with seismic reflection data. World leading experts present chapters covering different techniques and describe when, where, and how to apply them to improve petroleum exploration and production. It also explores the use of such techniques in monitoring CO2 storage reservoirs. Including case studies throughout, it will be an invaluable resource for petroleum industry professionals, advanced students, and researchers.

Most of the world's great volcanic massive suphide ore deposits, porphyry copper ores, and many of its richest gold veins occur in association with basalt-andesite-dactite-rhyolite laval suites that have erupted from ancient volcanic islands and their Precambrian equivalents. These volcanic arcs and their related aquatic-volcanic environments are now recognized as critical to an understanding of the evolution of the earth's crust and the origin of many important ore types. This book is concerned with the behavior of the 'ore elements'--copper, zinc, lead, cobalt, nickel, barium, and others--in young metamorphosed, volcanic arc lava suites, as these evolve from high-magnesium basalts to rhyolites. Using mostly the Pleistocene to recent lavas of the Solomon Islands younger volcanic suite, the author examines the patterns of abundance of these elements in rock constituents and describes the ways in which the metals may be enriched or impoverished in the residual melt as an arc lava series evolves from basalt to rhyolite. The book presents state-of-the-art information that will be indispensable to vulcanologists, geochemists, and mining geologists.

Volcanic eruptions are the clear and dramatic expression of dynamic processes in planet Earth. The author, one of the most profound specialists in the field of volcanology, explains in a concise and easy to understand manner the basics and most recent findings in the field. Based on over 300 color figures and the model of plate tectonics the book offers an insight in the generation of magmas and the occurrence and origin of volcanoes. The analysis and description of volcanic structures is followed by process oriented chapters discussing the role of magmatic gases as well as explosive mechanisms and sedimentation of volcanic material. The final chapters deal with the forecast of eruptions and their influence on climate. Students and scientists of a broad range of fields will use this book as an interesting and attractive source of information.

Volcanic eruptions can affect everything - nature, wildlife, people. From the earliest times, human resilience has been tested by this most severe environmental hazard resulting in a variety of collective responses - from despair and helplessness to endurance, increased worship of the gods, and even mass migrations. Past vulnerability breaks new ground by examining the histories of extreme environmental events, from the resent eruptions of Mount Merapi in Central Java to the prehistoric Toba supervolcanic eruption 74.000 years ago on the island of Sumatra. Experts from a broad and unconventional range of disciplines - from anthropology to literature studies and from archaeology to theology - discuss the impacts of volcanic eruptions in human history and prehistory. The book sets the scene for a 'palaeosocial volcanology' that complements and extends current approaches to volcanic hazards in the natural and social sciences by presenting historically informed and evidence-based analyses on how traditional societies dealt with these dangers -- or failed to do so.

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.

The mechanisms of magma movement, chemical differentiation and physical development, are derived from the geochemistry of igneous rocks, and from studying exposures of deep magmatic systems that have since solidified and been uplifted and exposed at the Earth's surface. The Ferrar Magmatic System of the McMurdo Dry Valleys in Antarctica provides an unparalleled example of a complete magmatic-volcanic system exposed in unprecedented detail. This book provides a unique and usual three-dimensional detailed examination of this system, providing insight into many magmatic processes normally unobservable, in particular how basaltic magma moves upwards through the crust, how it entrains, carries and deposits loads of crystals from great depths, and how this all contributes to Earth's evolution. Providing an explanation of how magmatic systems operate and how igneous rocks form, this is an invaluable resource ideal for researchers and graduate students in magma physics, igneous petrology, volcanology, and geochemistry.

The Sunday Times Bestseller A new, fully updated narrative edition of David Attenborough's seminal biography of our world, The Living Planet. Nowhere on our planet is devoid of life. Plants and animals thrive or survive within every extreme of climate and habitat that it offers. Single species, and often whole communities adapt to make the most of ice cap and tundra, forest and plain, desert, ocean and volcano. These adaptations can be truly extraordinary: fish that walk or lay eggs on leaves in mid-air; snakes that fly; flightless birds that graze like deer; and bears that grow hair on the soles of their feet. In The Living Planet, David Attenborough's searching eye, unfailing curiosity and infectious enthusiasm explain and illuminate the intricate lives of the these colonies, from the lonely heights of the Himalayas to the wild creatures that have established themselves in the most recent of environments, the city. By the end of this book it is difficult to say which is the more astonishing - the ingenuity with which individual species contrive a living, or the complexity of their interdependence on each other and on the habitations provided by our planet. In this new edition, the author, with the help of zoologist Matthew Cobb, has added all the most up-to-date discoveries of ecology and biology, as well as a full-colour 64-page photography section. He also addresses the urgent issues facing our living planet: climate change, pollution and mass extinction of species.

In this work, some of the latest advantages in the field of induced seismicity are concentrated for mining-induced (MIS), reservoir-induced (RIS), injection-induced (IIS) and extraction-induced (EIS) seismicity. Included are case studies and generalizations of investigations.
