This dataset includes raw and processed seismic data from the 2021 seismic survey at the San Emidio geothermal field in Nevada. In April and May 2021, 37 tri-axial short period seismographs were deployed in a 1.8km diameter cluster centered on 40.367278 N, 119.409019 W. The first data record started at 2021-04-06T07:09:10Z UTC and the last record ended at 2021-05-11T02:58:52Z UTC. The 37 stations included 29 SmartSolo IGU-16HR 3C all-in-one 5 Hz seismographs and 8 DataCube seismographs with 4.5 Hz HGS HG-6(B coil) tri-axial geophones. The raw format (level 0) data includes 353 GB of 500 sps SmartSolo data in native DLD format, 113 GB of 400 sps DataCube data in native DataCube format, and 3.4 GB of GPS data collected during the RTK GPS survey. The SAC data (level 1) files include 564 GB of hourly SAC files. The experiment was designed to monitor seismic activity before, during, and after the planned three-day plant maintenance shutdown April 19-21, 2021. The pumping stopped at 2021/04/19 12:51:45 UTC and resumed about 2021/04/21 21:00:00 UTC. The dataset is hosted in an AWS data lake, with an associated GDR data set providing the metadata. Links to both of these resources are included below. Additionally, this collection features data and metadata from a 2016 seismic survey at the same site for comparative analysis.

Included here are seismic data recorded at the San Emidio Geothermal field in Nevada. This passive seismic data were collected as part of the DOE-funded Subsurface Technology and Engineering R&D (SubTER) project to advance imaging and characterization of geothermal permeability. In December 2016, 1301 vertical-component seismic instruments were deployed at the San Emidio Geothermal field in Nevada. Data collection spanned a 160 hour timeframe, beginning on December 5th and ending on December 11th. Data are stored as individual files in one-minute increments in SEGD and MSEED formats and are downloadable as a zipped directory or available in a cloud-accessible format. Comprehensive metadata and project summaries are included in GDR submission 1386 (linked below as "2016 Seismic Survey Metadata at San Emidio").

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.

1301 Vertical Component seismic instruments were deployed at San Emidio Geothermal field in Nevada in December 2016. The first record starts at 2016-12-05T02:00:00.000000Z (UTC) and the last record ends at 2016-12-11T14:00:59.998000Z (UTC). Data are stored in individual files in one-minute increments. Data includes seismic station locations, seismic data logger specifications, instrumentation specifications, descriptions of data, a fracture finding summary and the final report for the 2016 WHOLESCALE seismic survey done in San Emidio, Nevada.

This submission includes a high-precision seismic event catalog estimated from seismic data collected at San Emidio, Nevada from April to May 2022. The catalog lists the precise time, location, and magnitude of microseismic events recorded during this period. Both the seismic data and microseismic event catalog were produced as part of the Water & Hole Observations Leverage Effective Stress Calculations and Lessen Expenses (WHOLESCALE) project. Attached here are the microseismic event catalog, a link to the raw seismic data, and a detailed description of methods used to create the catalog.
