High-resolution seismic imaging data acquired in 2021 across the West Winters Fault, Great Valley Fault System at Bigelow Hills, Yolo County, California
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 mixed P- and S-wave data using a 100-lb (45-kg) accelerated weight diagonally striking a 45-degree-sloped aluminum block. Shot gathers were created in SEG-Y format (Barry et al, 1975) by extracting several seconds of data from each node for each recorded shot time. This report provides the metadata needed to analyze the seismic data.
