Brief Description: This southern EARS depository contains a relocated earthquake catalogue and ground-motion table of 882 events spanning 1994 to 2022 with available time-series records within epicentral distances of 300 km. Additionally, the dataset includes a directory with the 10,725 instrument-corrected time series records used in the database, along with P- and S-wave phase arrivals for each record. The ground-motion database consists of two flatfiles: one file containing the 5% damped pseudo-spectral acceleration (PSA), peak ground acceleration (PGA) and velocity (PGV) ground-motion intensity measures for the horizontal components, and one file containing the Fourier amplitude spectra (FAS) metrics for the horizontal components.
