WHOLESCALE: Seismic Waveform Data from San Emidio, Nevada 2022

Description

Included here is a link to seismic waveform data collected at San Emidio, Nevada in 2022. The seismic instruments used were provided by EarthScope Consortium through the EarthScope Primary Instrument Center at New Mexico Tech. Data collected are available here through EarthScope at the link below. Detailed information on instrumentation, deployment, data collection, and data quality are provided in the attached paper. In the spring of 2022, the WHOLESCALE team deployed 450 SmartSolo seismic instruments at the San Emidio geothermal field in Nevada. The deployment was executed in three phases: stakes were placed in the ground at locations using hand-held GPS receivers, seismographs were implanted next to the stakes, and seismographs were turned on to begin recording data in April. Three phases were necessary due to the combination of limits on the seismographs' battery life and personnel availability. This was the first project to use the low-power A-to-D mode instead of the standard high-resolution mode, which allowed a trade of a decrease in the digitizer's effective number of bits (from 21.8 to 21.5) for a 30% increase in battery life. After approximately one month of observation, the seismographs were turned off, removed from the ground, and cleaned on May 6th (157 sites), May 7th (157 sites), and May 8th (136 sites). The data files were downloaded onto portable hard drives. The seismographs were then shipped to the PASSCAL Instrument Center where they were converted from the original (raw) SmartSolo (DLD) format to the more standard SAC at UW and also at the PASSCAL data Instrument Center. Methods and results of evaluating data quality are included in the attached paper and Word document.
