Data Files for Ground Motion Studies Pertaining to Southern California Basins and Other Geomorphic Provinces

This database is part of an on-going effort to compile and process recent earthquake ground motion data for seismic hazard assessment/analysis and model development. The provided database contains computed ground motion intensity measures (pseudo spectral accelerations, peak ground velocities) for processed earthquake time histories from events in Southern California. This includes records from the Next Generation Attenuation West-2 (NGA-West2) Project and data from earthquakes that have occurred since the completion of the NGA-West2 compilation (post-2010) such as, the 2019 Ridgecrest Earthquake Sequence and others. The data provide here was used to assess the site response of basins and other geomorphic provinces in southern California.
