Joint Experiment on the Spectrum of Earthquake Sources - Long-Period Instrumentation

Abstract

During this report period three long period FSK stations were installed in the Bear Valley area of California. The stations are at a distance of 30 to 45 km from the expected epicenters of small to medium sized earthquakes in Bear Valley. Two stations are located in shallow vaults on the west side of the Diablo Range. The third station is in a short mine adit on the east side of this mountain range. Data collected during first few months of operation contained no earthquakes of interest from the Bear Valley area. The only well recorded regional event was the Point Magu earthquake of 21 Feb 1973.
