Summary

In June of 2021, the U.S. Geological Survey conducted a high-resolution seismic survey at Winters, California. Seismic data were acquired using a DTCC SmartSolo 3-component nodal seismograph system ("node"), which continuously recorded at 2000 samples per second. Nodes were deployed 5 meters apart from west-southwest to east-northeast to create an approximately 800-m-long linear profile. P-wave data were generated primarily using a 500-lb (227-kg) accelerated weight drop at each recording station. In areas of difficult access, P-wave data were generated using a sledgehammer striking a steel plate. S-wave data were generated using a sledgehammer horizontally striking an aluminum block anchored to the ground. Every 50 meters we generated [...]

Purpose

The goal of this survey was to identify a strand of the Great Valley fault system, the existence of which we hypothesized based upon geomorphic and geologic evidence at the Bigelow Hills west of Winters, California. We use P- and S-wave tomography to locate the fault and constrain its geometry in the shallow subsurface (upper 100 meters).
