Almost immediately, research began to understand the unnamed fault and help local officials prepare for the next big seismic event, according to a press release from the University of California Riverside. In the case of Ridgecrest, some follow-up earthquakes came seconds after; the largest one came some 34 hours later. The length of a fault determines the magnitude of an earthquake, Ghosh said, so stress to the Garlock fault is a concern. While he stressed that he doesn't want to create undue alarm, Ghosh noted that aftershocks are reaching all the way to Garlock and it has been more active since Ridgecrest. The Mw7.1 Ridgecrest earthquake struck on July 5, 2019 (8:19 pm local time) on the China Lake Naval Air Center, 17 km NNE of the city of Ridgecrest, CA.
