1995 - Mori, J., D. J. Wald, and R. l. Wesson: Aftershock catalogs for the 1971 San Fernando and 1994 Northridge, California earthquakes
This special data set contains aftershock catalogs for the
San Fernando 1971 and Northridge 1994 earthquakes.
Authors summary:
3-D velocity structure and station corrections were used to relocate 1066
aftershocks from the San Fernando event that occurred during February through
April, 1971 plus 2572 aftershocks from the Northridge events that occurred in
January and February, 1994. All the phase data are available from the Southern
California Earthquake Center Data Center.
The resultant hypocenters for
events that were recorded on 6 or more stations and had rms errors of 0.3 sec
or less are shown in the figure below.
