Ridgecrest, CA 2009-2019 microseismicity catalog
收藏资源简介:
Catalog of microseismicity between 2009-01-01 and 2019-07-04 in the Ridgecrest, California area (latitudes: 35.50 -- 36.00, longitudes: -117.80 -- -117.30). This catalog captures 10 years of seismic activity before the July 2019 Ridgecrest sequence, which started with a M6.4 on 2019-07-04 and was followed by a M7.1 on 2019-07-06. v1.0.0: Earthquake catalog from "Enhanced Tidal Sensitivity of Seismicity Before the 2019 Magnitude 7.1 Ridgecrest, California Earthquake". The catalog contains 191,569 events and was built with the BPMF workflow (v2.0.0alpha, https://github.com/ebeauce/Seismic_BPMF). Check out the most recent version, v2.0.1, at https://zenodo.org/records/8393318! The catalog is a table with 11 columns: event_id: a unique event identifier, origin_time: origin time, UTC, of the event, longitude: longitude in decimal system, latitude: latitude in decimal system, depth: depth in km, hmax_unc: maximum horizontal uncertainty in km (from uncertainty covariance ellipsoid), hmin_unc: minimum horizontal uncertainty in km (from uncertainty covariance ellipsoid), az_hmax_unc: azimuth (angle from north) of maximum horizontal uncertainty in degrees, vmax_unc: maximum vertical horizontal uncertainty in km (from uncertainty covariance ellipsoid), Mw: moment magnitude, !! this column is mostly empty since most events were not well enough recorded to estimate a moment magnitude !! Ml: local magnitude.
