Cracks are seen on a road running parallel to Highway 178 which heads north from Ridgecrest to Trona on July 4, 2019. - Southern California was hit by its largest earthquake in two decades Friday, a 7.1-magnitude tremor that rattled residents less than 48 hours after another quake struck the same area. The shallow earthquake hit a sparsely populated area near the small town of Ridgecrest, around 150 miles (240 kilometers) northeast of Los Angeles, where it was also felt. (Photo by Frederic J.
