Excerpts from Reviews

“This book will be primarily of use to seismologists with a formidable mathematical understanding. Others need not apply.” –Comments in Earth Sciences: Geophysics, vol. 3, no. 6, 1973.

“Both Cerveny and Ravindra have made significant contributions to our understanding of these waves… They are well qualified as theoretical seismologists to present the mathematical complexities of the subject and to discuss the physical significance of their analysis.” –American Scientist, vol. 61, 1973.

“At once authoritative and comprehensive, the book will serve as an enormously useful guide… Written by recognized authorities in the field, and excellent, both in content and in style.” –Engineering Practice, vol. 16, no. 3, 1973.

“Altogether this book is the best known summary on the subject. It is an important book for all interested in the development of elastic wave theory.”—Geophysical Prospecting, vol. 20, September, 1972.

One of the consequences of the wave analysis presented in this book was the ability to distinguish between natural and artificial earthquakes. The U.S. Senate had refused to pass the Strategic Arms Limitation Treaty because of their suspicion that the Soviets were exploding nuclear bombs but claiming them to be natural earthquakes. With the ability to separate the two kinds of earth tremors, the Senate was willing to pass the Treaty; however, other political considerations intervened.
