2019 Ridgecrest, CA earthquake aftershock catalog

This data set is a catalog of hypocenter coordinates for aftershocks from the sequence following the 2019 M6.4 and M7.1 Ridgecrest, CA earthquake pair. This catalog was derived from raw seismic waveform data recorded by 152 seismic sensors using automated processing procedures. The catalog spans four months (1 June through 30 September 2019) starting about one month before the mainshocks and comprises roughly 95000 events.
