Bulletins Archive

Before 2001 in order to study significant earthquakes, scientists had to wait for SCSN to distribute a network bulletin highlighting that year’s earthquakes in print form. Below is an archive of the printable bulletins published by SCSN which display the earthquake catalog from each corresponding year.

To view the complete Southern California Earthquake Data Center catalog, spanning from 1932 to present, including the earthquakes archived here, go to scedc.caltech.edu.
