This new text provides comprehensive coverage of exploration seismology and elements of geology pertinent to exploration geology. It is profusely illustrated and contains workshops to aid understanding. Several appendices explain the math, equations, and answers of the selected exercise questions.
This is the completely revised and updated version of the popular and highly regarded textbook, Applied Geophysics. It describes the physical methods involved in exploration for hydrocarbons and minerals, which include gravity, magnetic, seismic, electrical, electromagnetic, radioactivity, and well-logging methods. All aspects of these methods are described, including basic theory, field equipment, techniques of data acquisition, data processing and interpretation, with the objective of locating commercial deposits of minerals, oil, and gas and determining their extent. In the fourteen years or so since the first edition of Applied Geophysics, many changes have taken place in this field, mainly as the result of new techniques, better instrumentation, and increased use of computers in the field and in the interpretation of data. The authors describe these changes in considerable detail, including improved methods of solving the inverse problem, specialized seismic methods, magnetotellurics as a practical exploration method, time-domain electromagnetic methods, increased use of gamma-ray spectrometers, and improved well-logging methods and interpretation.
Expanding the author's original work on processing to include inversion and interpretation, and including developments in all aspects of conventional processing, this two-volume set is a comprehensive and complete coverage of the modern trends in the seismic industry - from time to depth, from 3D to 4D, from 4D to 4C, and from isotropy to anisotropy.
The scope of engineering seismology includes geotechnical site investigations for buildings and engineering infrastructures, such as dams, levees, bridges, and tunnels, landslide and active-fault investigations, seismic microzonation, and geophysical investigations of historic buildings. These projects require multidisciplinary participation by the geologist, geophysicist, and geotechnical and earthquake engineers. A key objective of this book (SEG Investigations in Geophysics Series No. 17) by Öz Yilmaz is to encourage the specialists from these disciplines to apply the seismic method to solve the many challenging engineering problems they face. The broader scope of engineering seismology also includes exploration of earth resources, including groundwater exploration, coal and mineral exploration, and geothermal exploration. While focusing on the application of the seismic method to geotechnical site investigations, this book includes many case studies in all of the applications of engineering seismology.

Winner of the Book Prize of the Forum for the History of Science in America from the History of Science Society In 1906, after an earthquake wiped out much of San Francisco, leading California officials and scientists described the disaster as a one-time occurrence and assured the public that it had nothing to worry about. California Earthquakes explains how, over time, this attitude changed, and Californians came to accept earthquakes as a significant threat, as well as to understand how science and technology could reduce this threat. Carl-Henry Geschwind tells the story of the small group of scientists and engineers who—in tension with real estate speculators and other pro-growth forces, private and public—developed the scientific and political infrastructure necessary to implement greater earthquake awareness. Through their political connections, these reformers succeeded in building a state apparatus in which regulators could work together with scientists and engineers to reduce earthquake hazards. Geschwind details the conflicts among scientists and engineers about how best to reduce these risks, and he outlines the dramatic twentieth-century advances in our understanding of earthquakes—their causes and how we can try to prepare for them. Tracing the history of seismology and the rise of the regulatory state and of environmental awareness, California Earthquakes tells how earthquake-hazard management came about, why some groups assisted and others fought it, and how scientists and engineers helped shape it.
Covers the fundamentals of all currently used methods (seismic, electrical, electromagnetic, gravity, magnetic, borehole logging and remote sensing) and pays special attention to the seismic refraction and electrical resistivity techniques which are the ones most commonly used in engineering and groundwater geophysics. The main changes in this new edition of Applied Geophysics for Engineers and Geologists, apart from a general updating, and conversion to SI units, is a more extensive treatment of electromagnetic and induced polarisation methods, and of geophysical borehole logging. The seismic reflection method is also treated more fully in view of its great importance in petroleum prospecting. Problems, with answers are also included. Taken together, the changes are so great that this is virtually a new book, as is suggested by the change in title
Elements of 3D Seismology, third edition is a thorough introduction to the acquisition, processing, and interpretation of 3D seismic data. This third edition is a major update of the second edition. Sections dealing with interpretation have been greatly revised in accordance with improved understanding and availability of data and software. Practice exercises have been added, as well as a 3D seismic survey predesign exercise. Discussions include: conceptual and historical foundations of modern reflection seismology; an overview of seismic wave phenomena in acoustic, elastic, and porous media; acquisition principles for land and marine seismic surveys; methods used to create 2D and 3D seismic images from field data; concepts of dip moveout, prestack migration, and depth migration; concepts and limitations of 3D seismic interpretation for structure, stratigraphy, and rock property estimation; and the interpretation role of attributes, impedance estimation, and AVO. This book is intended as a general text on reflection seismology, including wave propagation, data acquisition, processing, and interpretation and will be of interest to entry-level geophysicists, experts in related fields (geology, petroleum engineering), and experienced geophysicists in one subfield wishing to learn about another (e.g., interpreters wanting to learn about seismic waves or data acquisition).
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.
