[Ed. – The epicenter was well inland from the heavily populated coast, and inland is where the damage has been as well. Definitely felt it here where I live (J.E.), about 50 miles south, but no damage locally that I’ve heard of. Hundreds of aftershocks, dozens in excess of 3.0 mag. Fortunately, the center point was in a very sparsely populated area on the north side of the Mojave Desert.]
Southern California was rocked by a magnitude 6.4 earthquake that jolted the Mojave Desert and was widely felt around the region as many prepared to celebrate Independence Day on Thursday.
The temblor hit at 10:35 a.m. and centered about 7 miles southwest Searles Valley, roughly 11 miles east-northeast of Ridgecrest, 109 miles north of San Bernardino and 121 miles north-northeast of Los Angeles, according to the U.S. Geological Survey.
It had a preliminary magnitude of 6.6 before being downgraded.
The “main” quake was preceded by magnitude 4.2 temblor that shook the area approximately 30 minutes before the large quake, seismologist Lucy Jones tweeted, calling the earlier tremor a foreshock.
