The July 1986 North Palm Springs, California, Earthquake - The North Palm Springs, California, Earthquake Sequence of July 1986
Abstract
An M_L = 5.9 earthquake occurred at 09:20 (UTC) on 8 July 1986 approximately 12 km northwest of the community of North Palm Springs, California. The epicenter of this earthquake was located between the Mission Creek and Banning strands of the San Andreas fault system at 34°0.0'N, 116°36.4'W. In this section of the San Andreas fault system, there is is a high level of diffuse microseismic activity, and it is not clear which of the many mapped fault traces is presently the most active strand (e.g., Allen, 1957; Matti et aI., 1985). The hypocentral distribution of the aftershocks as well as the focal mechanisms of the main shock and a few dozen aftershocks together suggest that the earthquake probably occurred on the Banning fault.

© 1986 Seismological Society of America. Analysis of this earthquake would have been impossible without the hard work and dedication of the Caltech and U.S. Geological Survey seismic data analysts, Riley Geary, Kathy Watts, Steven Bryant, Robert Norris, and Ruth Hannah. The temporary analog seismic stations were operated in the field by Rob Wesson, Craig Nicholson, John Coakley, and Gonzalo Mendoza of the U.S. Geological Survey. The P-wave arrival times from the temporary stations were supplied by Rob Wesson, Rex Allen, and Craig Nicholson. Egill Hauksson and Susanna Gross of the University of Southern California helped in the preparation of data for analysis. Tom Heaton, Steve Hartzell, and Egill Hauksson supplied critical reviews. Caltech's contributions to this study were funded in part by U.S. Geological Survey Cooperative Agreement No. 14-08-0001-A0257.Attached Files
