Welcome to these web pages, associated with the second edition of QUANTITATIVE SEISMOLOGY.
This textbook, a revision of the first edition (February 1980), was published in August 2002 by University Science Books. It may be ordered from www.uscibooks.com
These pages are intended to provide clarification, commentary, and corrections for the printed book. Input is invited particularly for these three areas, but is welcome on any aspect of the book.
I expect to accumulate additional references and problems, and discussion of new subject matter, possibly for inclusion in future reprints or a future edition. Such a plan can work only if readers of the book respond. Please be constructive, if critical.
Please send suggestions to me, via e-mail to:richards@LDEO.columbia.edu
These web pages are organized around the published book's Table of Contents, given below. Items within this TOC are linked to new material/corrections, etc. I hope we find some interesting corrections. Regrettably, we have accumulated some typographical errors
Pages will grow, if driven by input received.

The Leading Edge, issue of March 2003, pages 272--273.
The provenance of the picture used on the back cover may be of some interest. Here is that picture:
The picture is derived from an original photo taken by Tom Henyey in March 2000, on the occasion of Kei's retirement from the University of Southern California.
See below, for this original.
Kei apparently had a preference for white, Paul for red. But a (no doubt) wise editorial decision avoided depiction of such issues.
