RIDGECREST, Calif. (CNS) - A magnitude 5.4 aftershock to July 4's Ridgecrest Earthquake in Kern County struck in the same area Friday morning.

It struck at 4.07 a.m. at a depth of around 4.3 miles, its epicenter 9.7 miles west of Searles Valley, according to a computer-generated report from the U.S. Geological Survey.

Dozens of temblors greater than 3 magnitude hit the same region earlier Friday morning. USGS officials said there have been more than 200 aftershocks since Thursday’s 6.4 quake, CNN reported.

Then, at 5:38 a.m., a 4.1-magnitude aftershock struck, again at a depth of 4.3 miles, 9.4 miles West of Searles Valley, according to a computer-generated USGS report. It was followed 17 minutes later by a 3.7-magnitude temblor that hit at a depth of 3.7 miles.

There were no reports of injuries or damages stemming from the latest aftershocks.

Per a CNN report, the USGS said there’s a 20 percent change of a magnitude 6 or higher quake happening in California in the next week. There’s an 80 percent chance of a magnitude 5 or higher earthquake in the state.

The July 4th quake comes a week after San Diegans received their first "ShakeAlert" text message to test an earthquake warning system. While Los Angeles County residents already receive a similar alert, USGS hopes to expand the "ShakeAlert" system across the country eventually.
