Abstract

An electronic digital computer program has been developed for determining the source and origin time of a local earthquake by the method of least squares, using the times of arrival of direct and refracted P waves at stations in the Pasadena network. Output includes the geographic coordinates and depth of the source, the origin time, direct distances from the source to each station, and the difference between observed and computed arrival time of P at each station. Limitations to the applicability of the program are discussed.
