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.
