Record sections for two seismic refraction profiles in the Gabilan and Diablo ranges, California

In June 1967 the U.S. Geological Survey conducted a seismic-refraction survey consisting of two profiles parallel to the San Andreas fault; one in the Gabilan Range and one in the Diablo Range in central California. Each profile was about 200 km long and had five shot points distributed along it such that recording coverage is especially dense in the three inner shot points near the center of the profile. A description of the survey is provided by Stewart (1968). Shot-point locations are shown in Figure 1 and shot information is listed in Tables 1 and 2.
