2019 Ridgecrest, California Earthquake Surface Rupture - Photo Gallery by Dan Robinson

On July 5, 2019 at 8:19pm PDT, a magnitude 7.1 earthquake struck east of Ridgecrest, California, part of a sequence of quakes that included a M 6.4 foreshock the previous day. Both the M 6.4 and M 7.1 events broke the ground surface. The M 6.4 event produced minor left-lateral surface rupture along its trace. The M 7.1 produced spectacular right-lateral surface rupture features along most of its fault trace that slipped. While the greatest offests of over 6 feet occurred within the inaccessible-to-the-public Naval Weapons Station at China Lake, a long stretch of the surface rupture with offsets exceeding 3 feet was within reach across the desert landscape east of Ridgecrest.
