Abstract
We recovered 52 timed analog accelerograms from 25 aftershocks of the 1979 Imperial Valley earthquake, between 3:33p.m. P.d.t. October 16 and 5:43 a.m. October 31. The largest aftershock that we recorded (M_L =4.9) occurred at 4:16p.m. October 16. This aftershock triggered eight accelerographs; preliminary estimates of epicentral distance range from 7 to 35 km. The data from this aftershock may be useful for study of both source and wave-propagation phenomena in the Imperial Valley.

| Additional Information: | © 1980 United States Geological Survey. Several persons and institutions readily cooperated to help install the accelerographs quickly after the earthquake. These included A. Amini and B. Westermo of the University of Southern California, D. Helmberger of the California Institute of Technology, D. Halverson of Kinemetrics, Inc., and D. Hadley of Sierra Geophysics. Without their prompt response, this project would not have been possible. We also thank the following persons and institutes for allowing us to install an accelerograph on their property: Del Rio Country Club, Brawley Airport, Sam Etchegaray Livestock Co., the University of California Field Station, D. McDuffy, S. Fox, E. McGrew, and the California Institute of Technology. V. W. Lee, M.D. Trifunac, and M. Dravinski helped to digitize and process the accelerograms. The Los Angeles accelerograph network is supported by National Science Foundation Grant PFR 78-06926. | ||||||
