This book provides an approachable and concise introduction to seismic theory, designed as a first course for undergraduate students. It clearly explains the fundamental concepts, emphasizing intuitive understanding over lengthy derivations. Incorporating over 30% new material, this second edition includes all the topics needed for a one-semester course in seismology. Additional material has been added throughout including numerical methods, 3-D ray tracing, earthquake location, attenuation, normal modes, and receiver functions. The chapter on earthquakes and source theory has been extensively revised and enlarged, and now includes details on non-double-couple sources, earthquake scaling, radiated energy, and finite slip inversions. Each chapter includes worked problems and detailed exercises that give students the opportunity to apply the techniques they have learned to compute results of interest and to illustrate the Earth's seismic properties. Computer subroutines and datasets for use in the exercises are available at www.cambridge.org/shearer.

Exploration beyond the Earth has tended to overshadow the less spectacular but no less far-reaching and significant efforts to understand our home planet—efforts that have in recent years produced massive quantities of new data and, beyond that, a radically new way of looking at the Earth: a new worldview, a Whole Earth approach, a global concept. As a result, it no longer suffices to update older texts with a scattering of new facts or to write new ones based on older models. This genuinely new text, prepared by the chairman of the geophysics course team at England's Open University, bases itself firmly (but undogmatically) on these new discoveries, in particular on "knowledge of the large-scale features of the Earth's surface and interior in both their static and dynamic contexts. This is the global picture of the Earth as perceived by today's Earth scientist, although it carries with it no implication that will necessarily stand for all time without change, or even without radical change." The book opens with a general chapter summarizing this global picture, which is followed by three topics—chapters carefully designed to present three different aspects of geophysics and three different approaches to the science. Among them, they explore the Earth's crust, mantle, and core, but Smith has chosen to examine a few aspects in some detail rather than treat many in passing. This, in a sense, is a case-study text: it is meant for undergraduates, and only simple mathematics is called upon. The first topic is "The Earth's Crust and Uppermost Mantle." This typifies the observational branch of geophysics and draws its conclusions from experimental evidence supported by a broad data base. The second treats "The Earth's Heat and Thermal Properties," a subject that Smith calls "the most important of all branches of geophysics." Nevertheless, the material presented here is not well covered in most texts, at least in part because it represents a speculative approach to geophysics, in the sense that processes that occur deep within the Earth must be inferred from very few clear data, and they may be interpreted in quite different ways. The last topic is "Earthquakes: Characteristics, Prediction, and Modification." This is a subject of everyday interest and, in some parts of the world, of day-by-day interest—here, the frames of reference of "human time" and "geological time" coincide. Because of its social ramifications, this topical subject might be called an example of applied geophysics.

To understand continental drift and plate tectonics, the shifting and collisions that make and unmake continents, requires a long view. The Earth, after all, is 4.6 billion years old. This book extends our vision to take in the greatest geological cycle of all—one so vast that our species will probably be extinct long before the current one ends in about 250 million years. And yet this cycle, the grandest pattern in Nature, may well be the fundamental reason our species—or any complex life at all—exists. This book explores the Supercontinent Cycle from scientists' earliest inkling of the phenomenon to the geological discoveries of today—and from the most recent fusing of all of Earth's landmasses, Pangaea, on which dinosaurs evolved, to the next. Chronicling a 500-million-year cycle, Ted Nield introduces readers to some of the most exciting science of our time. He describes how, long before plate tectonics were understood, geologists first guessed at these vanishing landmasses and came to appreciate the significance of the fusing and fragmenting of supercontinents. He also uses the story of the supercontinents to consider how scientific ideas develop, and how they sometimes escape the confines of science. Nield takes the example of the recent Indian Ocean tsunami to explain how the whole endeavor of science is itself a supercontinent, whose usefulness in saving human lives, and life on Earth, depends crucially on a freedom to explore the unknown.

The novel Memphis 7.9 tells what happens to Memphis and the eastern United States, as seen through the eyes of those who are there, when a 7.9 magnitude earthquake strikes on the New Madrid Fault.The story begins a week before the earthquake happens. Grad student Chris Nelson's computer model predicts a strong temblor, but his University advisor opposes making public predictions.JQ McCrombie disbelieves any possibility of a major earthquake, and using bribes and low quality construction, makes a huge profit from the business of retrofitting highway bridges for earthquake safety.People in Memphis and throughout the Mississippi Delta live with varying degrees of disregard, complacency, and ignorance of the dangers of the New Madrid Fault, only 45 miles northwest of the city.The destined time arrives. In twenty-three and a half seconds, beginning at 9:34:09 CDT on a Saturday morning in May, a 70 mile fracture rips the earth's crust from Lepanto, Arkansas, under the Mississippi River, to Ridgely, Tennessee.Over the next thirteen minutes seismic waves from the giant magnitude 7.9 temblor destroy the upper Mississippi River Delta, including Memphis, and wreak havoc across the eastern United States, from Chicago to New Orleans, from Kansas City to Cincinnati.Ninety-one million people in twenty-two states feel the earth shake, hundreds of thousands are injured, tens of thousands are killed, millions are left homeless. Memphis is a lost city, cut off from the outside world.Six hours after the great earthquake, the realization of the full extent of the disaster begins to set in. Rescue and recovery become paramount in a land still shaking with aftershocks.

Remote Sensing deals with the fundamental ideas underlying the rapidly growing field of remote sensing. John Schott explores energy-matter interaction, radiation propagation, data dissemination, and described the tools and procedures required to extract information from remotely sensed data using the image chain approach. Organizations and individuals often focus on one aspect of the remote sensing process before considering it as a whole, thus investigating unjustified effort, time, and expense to get minimal improvement. Unlike other books on the subject, Remote Sensing treats the process as a continuous flow. Schott examines the limitations obstructing the flow of information to the user, employing numerous applications of remote sensing to earth observation disciplines. For this second edition, in addition to a thorough update, there are major changes and additions, such as a much more complete treatment of spectroscopic imaging, which has matured dramatically in the last ten years, and a more rigorous treatment of image processing with an emphasis on spectral image processing algorithms. Remote Sensing is an ideal first text in remote sensing for advanced undergraduate and graduate students in the physical or engineering sciences, and will also serve as a valuable reference for practitioners.

Models for the mechanical behavior of porous media introduced more than 50 years ago are still relied upon today, but more recent work shows that, in some cases, they may violate the laws of thermodynamics. In The Thermophysics of Porous Media, the author shows that physical consistency requires a unique description of dynamic processes that involve porous media, and that new dynamic variables-porosity, saturation, and megascale concentration-naturally enter into the large-scale description of porous media. The new degrees of freedom revealed in this study predict new dynamic processes that are not associated with compressional motions.The book details the construction of a Lorentz invariant thermodynamic lattice gas model and shows how the associated nonrelativistic, Galilean invariant model can be used to describe flow in porous media. The author develops the equations of seismic wave propagation in porous media, the associated boundary conditions, and surface waves. He also constructs the equations for both immiscible and miscible flows in porous media and their related instability problems.The implications of the physical theory presented in this book are significant, particularly in applications in geophysics and the petroleum industry. The Thermophysics of Porous Media offers a unique opportunity to examine the dynamic role that porosity plays in porous materials.
