This series includes technical reports prepared by faculty, students and staff who are associated with the John A. Blume Earthquake Engineering Center at Stanford University. While the primary focus of Blume Center is earthquake engineering, many of the reports in this series encompass broader topics in structural engineering and materials, computational mechanics, geomechanics, structural health monitoring, and engineering life-cycle risk assessment. Each report includes acknowledgments of the specific sponsors for the report and underlying research. In addition to providing research support, the Blume Center provides administrative support for maintaining and disseminating the technical reports.

On October 15, 1979 an earthquake of local magnitude 6.6 was triggered on the Imperial Fault. The epicenter was located 5 kms south of the U.S.-Mexico border. The Imperial Fault has been seismically active for years. The last major event was the 1940 El Centro Earthquake. A substantial number of strong motion accelerograms were recorded during this most recent event, providing an ideal data base to study near-field ground motion. This work investigates the character of the strong motion during this earthquake. A study is undertaken that considers various means of characterizing the intensity of ground shaking and the methods used to describe their behavior.
