Two P-wave vibroseis reflection profiles were collected in the urban area of Santa Rosa, Calif. Santa Rosa Creek is an east-west profile, and Piner Creek is a north-south profile. The Piner Creek profile is about 5.1 km, and the Santa Rosa Creek profile is about 7.9 km. Data were acquired using a 14 second vibrator linear sweep from 15 to 120 Hz with a total record length of 16 seconds to produce a 2 second correlated field record. Four sweeps were stacked at each shot-point. The sample interval was 2 ms. Geophone spacing was 5 m and the shot-point interval was 10 m. Geophones were 8 Hz single vertical component. Generally, 144 channels were recorded in an “off-end-push” configuration. The data files are SEG-2 format, uncorrelated, and are a stack of 4 vibrator sweeps.
