This report contains summaries and plots of the results of the completed processing performed on the six most significant strong-motion records obtained at five California Division of Mines and Geology (CDMG) accelerograph stations during the Imperial Valley earthquake of 15 October 1979.
Information on all the CDMG strong-motion records recovered from this earthquake as well as on the CDMG accelerograph stations from which these records were obtained was published by CDMG in 1980 in its Preliminary Report 26. Copies of Preliminary Report 26 as well as additional copies of this report are available from the California Strong Motion Instrumentation Program in Sacramento, California.
Digital data of the processed records corresponding to the plots of the Volume 1, 2, 3 (uncorrected data, corrected data, and Fourier and response spectra, respectively) may be obtained from CDMG at the above address.
Processed data of additional records of this earthquake may be found in U.S. Geological Survey Open-File Report 80-703 (Brady and others, 1980).
