Index

“The continued popularity of this text is testament to the meticulous detail with which important mathematical formulas are derived; there simply is nothing of any importance that is glossed over or omitted.”
-Pure and Applied Geophysics, 2005 (162)

“An excellent study and reference book for seismologists well-grounded in the methods of mathematical physics. This updated version of Aki and Richard’s classical geophysical text deserves a place in every serious geophysicist’s library.”
-The Leading Edge

“For more than twenty years, Aki and Richards’ classic has maintained its position as the most complete and accessible text on theoretical seismology. Now brought up to date throughout, and with several completely revised chapters, this book will remain “The Bible” of the subject for years to come.”
-Bruce R. Julian, USGS

“An important renewal of a classic geophysics text. The clarity of the chapters that describe fundamental seismic wave propagation remains undiminished.”
-Jeffrey Park, Yale University

“Still the preeminent text on analytic theory and methods in seismology.”
-D.J. Andrews, USGS

From reviews of the first edition:

“This truly exquisite text/monograph provides advanced students and professionals with a wonderfully detailed and comprehensive but lucid account of physical, mathematical and instrumentational principles that lie at the quantitative heart of modern seismology…An extraordinary publishing event.”
