WATCH: Dozens of earthquakes rattle California, including magnitude 6.0 quake

The earthquakes triggered rockslides that closed roadways, but there were no reports of major injuries or damage.


Several earthquakes rattled Northern California within minutes of each other Thursday afternoon, according to the United States Geological Survey.

Between Walker and Coleville in Mono County, about 23 miles southwest of Smith Valley, Nevada, a magnitude 6.0 earthquake was recorded around 3:50 p.m.

After that quake, the USGS reported several other shakes either in Nevada or across the state border in Mono, Tuolumne and Alpine counties.

The earthquake was originally reported as magnitude 5.9 but was since revised to 6.0 around 5:45 p.m. by the USGS.

An earthquake in Farmington in San Joaquin County was originally reported by the USGS but that entry was since taken off the list of recent quakes. California seismologist Dr. Lucy Jones explained automatic systems that locate quakes sometimes get confused, especially if there are not many stations in the area.

The earthquakes triggered some rockslides, but no major damage or injuries have been reported.

Coleville-Walker KOA Campground co-owner Scott Burkard described the earthquake.

"I look down and literally the ground is just shaking," Burkard said. "I've never seen where the ground is just moving like a salt and pepper shaker."

At a nearby flea market, glasses and antiques were shattered across the floor.

"It just popped so hard, it just felt like it lifted the building up and was slamming it back down," one resident said.

The USGS said there were reports of the earthquake being felt from San Francisco to Las Vegas.

Geologist Austin Elliot said the earthquake was on the Antelope Valley Fault, which is very active. But this was the largest on the fault since 1994.

He said although it was a "fairly large earthquake," the activity is not uncommon in the area.

Cal Office of Emergency Services was preparing for the weekend's heat wave when the shifting plates prompted them to shift plans.

We felt the earthquake, and immediately pivoted and put on the earthquake hat," Deputy Director of Planning, Preparedness, and Prevention Lori Nezhura said.

Elliot said more earthquakes are likely to continue to occur in the aftermath of the initial strike, but that it was just a 6% chance any of those would be greater than a 6.0.

"It's a particularly unlikely scenario," Elliot said.

Elliot said the state’s ShakeAlert warning system activated in Sacramento 23 seconds before the shaking started.
