Data Release for a 2020 High-Resolution Seismic Survey across Northeastern Edwards Air Force Base, Kern County, California

Metadata Updated: October 28, 2025

In June of 2020, the U.S. Geological Survey conducted a high-resolution seismic survey at Edwards Air Force Base in Kern County, California. Seismic data were acquired using 601 DTCC SmartSolo 3-component nodal seismometer systems (“nodes”), which continuously recorded at 2000 samples per second. Nodes were deployed 5 meters apart along a southwest-northeast trend to create an approximately 3-km-long linear profile. P-wave seismic sources were generated primarily using a 500-lb (227-kg) accelerated weight drop at each recording station. P-wave sources were also generated at every 40 stations using downhole explosions. Fault-zone-guided waves were generated using explosive sources that were placed within a mapped trace of a nearby fault (Kramer Hills Fault zone), located approximately 1 km southeast of the seismic profile. 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.
