On July 4, 2019, a series of earthquakes occurred near Searles Valley and Death Valley National Park in California. A 6.4 MW mainshock occurred at 10:33 a.m. PDT (17:33 UTC) in a remote area of San Bernardino County. The mainshock was preceded by several foreshocks, and hundreds of aftershocks were detected after the mainshock. Relatively minor damage resulted, though some building fires were reported in Ridgecrest, California, near the epicenter. Effects were felt across much of southern California, parts of Arizona and Nevada, and as far south as Baja California, Mexico. An estimated 20 million people experienced the earthquake.
