P- and S-phase data from local earthquakes in Southern California for 1966 to 1975


The purpose of this note is to describe a card-image computer tape now available with earthquake epicenter and P- and S-phase data for local earthquakes in Southern California during the 10-year period of 1966 through 1975. The tape is readable on an IBM 370/158 computer using standard FORTRAN READ statements. The tape is currently being used for several research projects including event relocation, velocity, P-delay, and magnitude studies. This research resource is being made available to all scientific investigators.

I thank Marla Turner who did most of the long and difficult task of data keypunching and organization and the many other workers who read phases and punched cards for this data set. I thank the U.S. Geological Survey personnel who kindly provided copies of data cards for their stations under the Caltech-USGS cooperation program in Southern California. The efforts of the technical personnel who have dependably maintained the stations and equipment that are the source of this data are greatly appreciated.
