  "description": "In February 2015, the U.S. Geological Survey conducted a high-resolution seismic survey across the West Napa Fault zone at Hendry Winery in Napa, California (Fig. 1). Geophones were deployed every 3 to 5 meters along a southwest-northeast trend to create an approximately 400-m-long linear array. Data were recorded by two Geometrics Stratavisor NZ-60TM seismographs. Both P-wave and S-wave seismic energy was generated at shotpoints located in-line with the recording array, with approximately 1 meter lateral spacing of shotpoints from each geophone. P-wave seismic sources consisted primarily of shots from a Betsy SeisgunTM, while for the northeast one-third of the array, P-wave sources were generated by vertical strikes of a sledgehammer on a steel plate. S-wave sources were generated by horizontal strikes on both sides of an aluminum block that was anchored to the ground. Fault-zone-guided-wave energy was generated by detonating small explosive charges in shallow boreholes within mapped traces of the West Napa Fault zone. All data was recorded by 120 vertical-component or single-component horizontal geophones. Each seismograph created a separate SEG-2-formatted data record (SEG Engineering and Groundwater Geophysics Committee, 1990) for each shot. Data records from both seismographs were combined to form a single shot gather containing all channels in the recording array.",
