High-resolution seismic imaging data acquired in 2021 across the West Winters Fault, Great Valley Fault System at Bigelow Hills, Yolo County, California

Metadata Updated: October 29, 2025

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.
