Abstract
Epicenters, origin times, and other pertinent data on approximately 9000 earthquakes in the Southern California region, determined by the Seismological Laboratory at Pasadena for the period from January 1, 1934 to May 17, 1963, have been entered on IBM punched cards. This card catalog may be used as input for programs run on the IBM 7090, and has been converted to punched tape for input to the Bendix G-15D in use at the Laboratory. Programs now operational on the G-15D will produce from the catalog lists of earthquakes which satisfy given criteria of geographical location and/or magnitude range. A system of G-15D programs for calculating from the catalog the distribution of seismicity over the region is described.
