The second
edition of the Aki-Richards textbook was published by University Science Books in August 2002 as a
hardback. It appeared in one
volume that was a substantial rewrite of the original two-volume first edition.
In April 2009 the hardback was reprinted as a paperback that corrected many typos and a few Figures.
The current paperback version of the second edition may be ordered from www.uscibooks.com
Sadly, the death of the senior author in May 2005 is noted.
A short memorial to Keiiti Aki was published in the September/October 2005 issue of Seismological Review Letters (download 1.6 Mb pdf file).
Feel free to send further corrections and suggestions to Paul Richards, 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 in a few places to new material/corrections, etc. Toward the end of these web pages, are several photos of the senior author, most of them taken December 2004 at a dinner in celebration of his life and work.
Regrettably, as indicated above, we accumulated some typographical errors in the hardback version of 2002. They were corrected in the paperback version, but perfection is elusive. See the current list of paperback typos.
Here, then, is the current Table of Contents of the paperback version of the
second edition:

Reviews
The Leading Edge, issue of March 2003, pages 272--273.
The provenance of the picture used on the back cover of the second edition 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.
In 2003, Kei and Paul attended the IUGG/IASPEI meetings in Sapporo, Japan. Again, the preference for red and white:
In December 2004 in San Francisco, when Kei was awarded AGU’s highest honor (the Bowie medal), Willie Lee and John McRaney organized
a splendid and very happy dinner and celebration of Kei’s life and accomplishments. Here are some of the pictures on that occasion (all taken by Paul).
The first was on the night of the actual award; the others, at the dinner honoring Kei:
