Description:

This dataset is part of an on-going effort to develop a sub-regional site response model for the San Francisco Bay Area (SFBA) in northern California. We performed semi-automated, component-specific data processing with the aim of optimizing usable bandwidth following procedures consistent with Next Generation Attenuation (NGA) project protocols for 28 recent earthquakes not included in prior data collection efforts (Bozorgnia et al. 2014; Wang 2020; Buckreis 2022). These events were selected because they were recorded by at least one station within the SFBA, although all available records for each event were processed regardless of their site locations. The present dataset includes computed intensity metrics including peak velocity (PGV) and acceleration (PGA), 5% damped spectral accelerations (PSA), effective amplitude spectra (EAS) (Kottke et al. 2021), cumulative absolute velocity (CAV), thresholded cumulative absolute velocity (CAV5), Arias intensity (IA), and times to achieve every 5th percentile of the maximum Arias intensity (used to compute significant durations); metadata related to source, path, and site conditions; intensity metrics are computed for the as-recorded components (H1, H2, and V) and for the minimum, median, and maximum combined horizontal components as defined by Boore (2010) (RotD0, RotD50, and RotD100, respectively). Note that the unprocessed time-series in their original raw format can be obtained from the Incorporated Research Institutions for Seismology (IRIS; Trabant et al. 2012). The processed time-series data can be obtained at https://gmdatabase.org.
