Summary
This dataset includes processed ground-motion records and horizontal pseudospectral accelerations (5-percent-damped) from magnitude 3.5-7.1 earthquakes occurring in the vicinity of the Great Valley, California, between 2000 and 2022.
The dataset includes 12,044 records from 564 earthquakes and 254 stations.
Spectral values are provided at 21 periods (0.01-10 s).
It also includes the basin depth models as GeoTiff raster files, which are provided as Z1.0 and Z2.5 (depths to the 1.0 and 2.5 km/s shear wave speed isosurfaces) values averaged from the corresponding values in the U.S. Geological Survey (USGS) San Francisco Bay region three-dimensional seismic velocity model version 21.1 (doi: 10.5066/P9TRDCHE) and the USGS National Crustal Model (NCM) for seismic hazard studies version 220311 (doi: 10.5066/p9T96Q67).
The dataset includes Vs30 (time averaged shear wave speed in the top 30 m) values for each station from Thompson and others (doi: 10.1785/0120130312).
