Earthquake rocks southern California for second time in two days

Seismologists warned that further episodes were expected.

SAN FRANCISCO — A 7.1-magnitude earthquake rattled Southern California on Friday night, one day after the strongest recorded quake there in 20 years struck — and seismologists warned that further episodes were expected.

The U.S. Geological Survey reported that the latest earthquake’s epicenter was in the Mojave Desert, 11 miles from Ridgecrest, California — near where a 6.4-magnitude quake had hit about 36 hours earlier. Since Thursday’s earthquake, the area had been jolted by a series of rolling aftershocks, including one of a 5.4-magnitude that roused Californians on Friday morning.

“Hold on, it’s going again,” Jade Alexander, the manager of Rodeway Inn & Suites in Ridgecrest, said in a phone interview after an aftershock Friday night. She said the aftershocks were coming every five minutes.

Although the area where the earthquake struck is sparsely populated, the Navy has a weapons testing facility just outside Ridgecrest, the Naval Air Weapons Station China Lake.

“It’s constant,” said Alexander, whose hotel in Ridgecrest is less than a five-minute drive from the naval station. “My anxiety level is over the limit.”

“The floor is cracked,” she added, saying that bookshelves, lockers and televisions were thrown to the floor.

The quake, which struck at about 8:20 p.m. local time, was felt across a much wider area than Thursday’s, with reports of power failures in Los Angeles and of some damage in San Bernardino County. It was also felt in Las Vegas, although the Nevada Highway Patrol had received no reports of damage to roads or bridges.

Mick Gleason, a supervisor of Kern County, which includes Ridgecrest, said that some people had been injured but that no deaths had been reported. There were at least two fires, including one at a mobile home park, he told CNN. One big concern was gas leaks. Kern County Fire Chief David Witt said that it appeared that no buildings had collapsed.

Lucy Jones, a seismologist, said during a Friday night briefing by the U.S. Geological survey that there would be more aftershocks. “It is clearly an energetic system,” she said.

Leena Panchal, a manager of Americas Best Value Inn & Suites, another hotel in Ridgecrest, about 150 miles northeast of Los Angeles, said people rushed outside because they felt unsafe being indoors.

“It was so bad,” she said of Friday’s earthquake and its aftershocks. “I am scared. I have two children and no one is taking care of us.”

Panchal was seated during the earthquake but said that the shaking was so violent it would have been impossible to stand up. “It was very strong,” she said. “I’m still feeling dizzy.” Standing lamps were thrown to the floor.

The electricity was cut during the earthquake but came back on afterward, Panchal said.

At 8:21 p.m. local time, the Los Angeles Fire Department issued an earthquake alert from its Twitter account.

“Prepare For Aftershocks,” the tweet said. “When Shaking Starts: DROP, COVER, HOLD ON!”

In Los Angeles, fire officials reported localized power failures and wires down in several neighborhoods but said that no major damage to infrastructure had been identified.

In San Bernardino County, fire officials said that there was more damage from the Friday night earthquake than there was from the one the day before. The officials reported that homes had been shifted, foundations had been cracked and retaining walls had collapsed.

Tom Heaton, an earthquake expert at the California Institute of Technology, said the earthquake Friday night appeared to have taken place northwest of Thursday’s earthquake. The rupture was about 10 to 15 miles long, and the duration was around seven seconds. Friday’s earthquake was much larger than Thursday’s; the total energy released was about eight times greater.

For now, the earthquakes appear to be localized. There is “no plausible connection” between these earthquakes and the San Andreas, the larger and potentially more destructive fault that runs from the Gulf of California to well north of San Francisco, Heaton said.

“But in this business, I don’t like to ever say things can never happen,” Heaton said.

The region where Thursday’s and Friday’s earthquakes struck is characterized by a complex set of faults that have helped form geological features called basins and ranges.

“I like to tell people that earthquakes are very social in the basin and range; they don’t like being alone,” Heaton said. “I would be surprised if this thing just stopped.”

The largest known earthquake in the area occurred in 1872 and was a magnitude 8, one of the largest in California.

Friday night’s earthquake came during the fourth inning of the Dodgers home game against the San Diego Padres in Los Angeles, where camera footage showed the stadium shaking. The game was not interrupted. But in Las Vegas, where an NBA summer league game took place between the New York Knicks and the New Orleans Pelicans, the action was halted because of the quake.

Frank Jackson, the Pelicans’ point guard, was bringing the ball upcourt when he felt the earthquake.

“That was crazy,” Jackson said. “I felt like someone was pushing my hip — I kind of leaned this way and was like, ‘Oh my gosh, what is going on?’ And then I saw everything shaking.”

Tim Dorcey of Santa Monica noticed something was amiss when the wine bottles in his home began rattling on Friday night. “That happened and I thought, ‘Oh aftershock,’ ” Dorcey said by phone. “And then it stopped. Fifteen seconds later it started going again. I hopped up and got away from my windows.”

Dorcey said the shaking began again and went on for a minute. “It kept getting stronger and stronger,” he said.

Giovanna Gomez of Bakersfield said Friday’s earthquake felt like Thursday’s.

“I was in my living room with my parents, and all of a sudden we started feeling the earth slowly moving,” Gomez said. “And then it started getting bigger, just rocking back and forth.” She said the family promptly went outside and reported no damage and complained of dogs barking.
