Modern Global SeismologyBy
- Thorne Lay
- Terry Wallace
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.
Upper-division undergraduate and first-year graduate students in earth science, geophysics and geology; seismology, and applied mathematics/mechanics; professionals in related fields wanting an introduction to global seismology; libraries; and institutions.

"...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."
