Modern Global Seismology / Edition 1

by Thorne Lay, Terry C. Wallace

Overview

Intended as an introduction to the field, Modern Global Seismology is a complete, self-contained primer on seismology. It features extensive coverage of all related aspects, from observational data through prediction, emphasizing the fundamental theories and physics governing seismic waves—both natural and anthropogenic. Based on thoroughly class-tested material, the text provides a unique perspective on the earths large-scale internal structure and dynamic processes, particularly earthquake sources, and on the application of theory to the dynamic processes of the earths upper skin.

Authored by two experts in the field of geophysics. this insightful text is designed for the first-year graduate course in seismology. Exploration seismologists will also find it an invaluable resource on topics such as elastic-wave propagation, seismicinstrumentation, and seismogram analysis useful in interpreting their high-resolution images of structure for oil and mineral resource exploration.

About the Author

As Principal Associate Director for Global Security, Wallace leads Laboratory programs with a focus on applying scientific and engineering capabilities to address national and global security threats, in particular, nuclear threats. Wallace is also the Senior Intelligence Executive at LANL. Wallace served as Principal Associate Director for Science, Technology, and Engineering from 2006 to 2011 and as Associate Director of Strategic Research from 2005 to 2006. In those positions, Wallace integrated the expertise from all basic science programs and five expansive science and engineering organizations to support LANL’s nuclear-weapons, threat-reduction, and national-security missions.

Editorial Reviews

"...this is an important new book that will become a standard for introductory seismology courses taught by many universities. I am already using it this semester and am getting positive feedback from my students. I also would recommend it to a range of geophysicists who wanted to educate themselves further on the fundamentals of seismology." —Gary L. Pavlis, Department of Geological Sciences, Indiana University
