It means it was built with somewhat modern earthquake … They found that ruptures of a few larger, but many smaller, faults occurred during both earthquakes. Fortunately, these large shocks occurred in the remote southern California desert, so caused no deaths and only modest damage. They struck on faults that had not been mapped, and, in a rare order of events, the larger quake followed 34 hours after the smaller one. … The 2019 Ridgecrest Earthquakes were California’s biggest in nearly two decades. Within days after the 2019 Mw 7.1 Ridgecrest earthquake, we responded promptly to deploy four DAS arrays around the rupture region.
