Seismicity of the Southern California region: 1 January 1972 to 31 December 1974


This listing of earthquakes and epicenter maps is an update to the southern California local earthquake catalog published in Seismicity of the Southern California Region 1 January 1932 to 31 December 1972 by Hileman et al. (1973). Earthquakes in 1972 are relisted here because of numerous additions that resulted from an intensive study of seismicity in the Los Angeles basin. The basic seismological data was obtained from the southern California network of the Seismological Laboratory.
