This report represents a joint effort by the OSMS, CDMG and the U.S. Geological Survey (USGS). The report summarizes all strong-motion accelerograph records recovered from the August 6, 1979 Coyote Lake earthquake. The majority of accelerograms were recorded at stations operated by the OSMS-CDMG and USGS; the latter organization operates a network of instruments that belong to various federal agencies. Documentation of strong-motion data for the Coyote Lake earthquake best serves the scientific community if presented as a single data set.

Reasonable precautions have been taken to ensure the accuracy of the material presented; however, the preliminary nature of the report makes it subject to change upon further verification. Measurements and scalings of the accelerograms are not recommended for use in detailed studies because of possible photo copy distortions during reproduction. A report on the processed data from close-in stations is in preparation and will be issued in the near future.
