Abstract

This continues the previous report of Gutenberg and Richter [see “References” at end of report, 1945 a]. Three papers reported as in press in 1945 have since appeared [Gutenberg, 1945 a and b; Gutenberg and Richter, 1945 b]. Wood's paper [pending] on local epicenters and fault structure in Southern California has been submitted to the Seismological Society of America. As the first paper of Gutenberg and Richter [1941] on seismicity of the Earth is now out of print, a revision has been undertaken, incorporating the results of the supplementary paper [Gutenberg and Richter, 1945 b] and much new material. No epicenter has been accepted from the International Summary or any other source without careful revision. A large file of individual station bulletins has been accumulated through correspondence, as exchange or on loan. This has facilitated assigning magnitudes, and has much improved the statistics of large shocks. Magnitudes have been assigned to all shocks, shallow and deep, of magnitude 6 or larger, used in the study. For further statistical investigation the data have been entered on punch cards, which now number about 2500 for shallow earthquakes, and over 1000 for deep shocks. It is hoped that it will be possible to publish the full list of epicenters.
