USA, California, Ridgecrest: 1993-2019

Summary

The Ridgecrest cluster is named for the town of Ridgecrest in California, U.S.A. The cluster is based on major earthquake sequence that began on July 4, 2019 with a 6.4 Mw event, followed two days later by a 7.1 Mw event. The cluster includes earlier seismicity in the region, all of moderate magnitude. Arrival time data for these earlier events is from the ISC Bulletin. The July 2019 sequence uses arrival time data mainly from the NEIC, but a few of the larger events also have some data from the ISC. The cluster could be relocated fairly well with free depth but the final runs were done with depth fixed because of instability in a few events. Because of the extremely dense network of stations in this region, the calibration level is [...]
