Southern California was hit by another big earthquake at 8:19 p.m. local time Friday, after a quake rattled the region a day before. The U.S. Geological Survey reported the magnitude as 7.1 with a shallow depth of about 10.5 miles.
There were no immediate reports of any casualties or significant injuries.
It was centered near the same Mojave Desert site as the 6.4 quake on Thursday and near the small city of Ridgecrest.
“We haven’t had an earthquake this size in 20 years,” seismologist Lucy Jones told reporters at Cal Tech Friday, speaking of earthquakes in Southern California.
A USGS official said people should expect at least one more of magnitude 6.1 or higher.
Jacob Margolis, host of KPCC’s podcast The Big One: Your Survival Guide, told NPR’s Weekend Edition that a 7.1 magnitude earthquake releases more than 11 times the energy of a 6.4 magnitude earthquake.
Margolis told NPR that the combination of events of Thursday and Friday — a 6.4 magnitude earthquake, followed by a 7.1 magnitude earthquake — had a less than 1% chance of happening. Margolis said there would be a less than 2% chance of another magnitude 7 earthquake happening on Saturday.
Reporting from a mobile home park where the earthquake had caused significant damage, Eyton Wallace of KGET News told NPR’s Weekend Edition that hundreds of aftershocks had been taking place, and they were happening “every few minutes.”
Ridgecrest Mayor Peggy Breeden told reporters early Saturday that many residents were sleeping outdoors overnight.
The city’s police chief, Jed McLaughlin, also said “nothing but minor injuries” have been reported.
Local authorities said they were “inundated” with reports of gas leaks at residences and have received reports of at least two structure fires.
A spokesperson for electricity provider Southern California Edison told NPR as of 7:30 a.m. local time Saturday, 50 customers in the city of Ridgecrest were still without power.
Megan Person of the Kern County Fire Department told The Associated Press there were reports of multiple injuries and multiple fires.
The California Highway Patrol said portions of State Route 178 were closed because of rock slides, but they were quickly reopened.
SR-178 through the Kern River Canyon is closed due to rock slides, please avoid the area. #trafficalert

California Gov. Gavin Newsom requested a presidential emergency declaration from the White House. He declared a state of emergency in San Bernardino County early Saturday. Newsom earlier put the state operations center of the Governor’s Office of Emergency Services on its highest alert.
Jones went with new terminology — changing the description of Thursday’s quake to a foreshock in light of the larger one.
So the M6.4 was a foreshock. This was a M7.1 on the same fault as has been producing the Searles Valley sequence. This is part of the same sequence –

Jones said the region is in the midst of an earthquake sequence and “another magnitude 6 would not be surprising to anybody.”
Reports say the quake was felt as far as Sacramento to the north, Mexico to the south and Las Vegas to the east, according to The Associated Press.
The rolling was felt at sports events throughout the region.

In Las Vegas, a summer game between the New Orleans Pelicans and New York Knicks was stopped early because of the earthquake.
Few injuries were reported from the quake the day before, although broken gas lines caused two house fires.
Faults, the breaks in the planet’s crust where earthquakes occur, are plentiful in California.
“If you looked at a map of southern California and wanted to imagine all the faults, just throw a pile of spaghetti down on it, and all those little strands would be faults all over the place,” Margolis said.
