Description
Two days after the May 2, 1983, Ms 6.7 earthquake near coalinga, CA, the USGS began a seismic refraction experiment in the area. One objective was to record aftershocks using a dense, linear array of portable seismographs in order to derive a velocity model for the middle to lower crust in this region. Such a model would, in conjunction with the velocity model derived from a parallel survey using explosive sources (Colburn and Walter, 1984), provide further information on the geologic structure of the Coalinga area.Full size version of plates available in additional file with the report.
