Los Angeles: A quake with a magnitude of 7.1 jolted much of California, cracked buildings, set fires, broke roads and caused several injuries while seismologists warned that large aftershocks were expected to continue.
The quake preceded by Thursday's 6.4-magnitude temblor in the Mojave Desert was the largest Southern California quake in at least 20 years and was followed by a series of large and small aftershocks, including a few above magnitude 5.0.
There is about a 1-in-10 chance that another 7.0 quake could hit within the next week, said Lucy Jones, a seismologist at the California Institute of Technology and a former science adviser at the U.S. Geological Survey.
The chance of a 5.0-magnitude quake "is approaching certainty," she added.
However, the quake was unlikely to affect fault lines outside of the area, Jones said, noting that the gigantic San Andreas Fault was far away.
The quake struck at 8:19 p.m. and was centered 11 miles from Ridgecrest in the same areas where the previous quake hit. "These earthquakes are related," Jones said, adding that the new quake probably ruptured along about 25 miles of fault line.
The quake was felt as far north as Sacramento, as far east as Las Vegas and as far south as Mexico. The area in and around Ridgecrest, already trying to recover from the previous temblor, took the brunt of damage.
State Route 178 in Kern County was closed by a rockslide, and video showed a stretch of roadway had sunk. A fire at a mobile home park burnt several trailers.
But Kern County Fire Chief David Witt said there had been no immediate reports of building collapses or deaths, although injury reports sent paramedics scrambling.
"We know of no fatalities. There have been a lot of ambulance calls for help," Kern County Fire Chief David Witt said at a news conference. "We're launching a lot of people ... I am very confident that we can take care of the situation." San Bernardino County firefighters reported cracked buildings and one minor injury.
In downtown Los Angeles, 150 miles away, offices in skyscrapers rolled and rocked for at least 30 seconds. Andrew Lippman, who lives in suburban South Pasadena, was sitting outside and reading the paper when Friday's quake hit.
"It just started getting stronger and stronger, and I looked into my house and the lamp started to sway. I could see power lines swaying," he said.
"This one seemed 45 (seconds)... I'm still straightening pictures." Gov. Gavin Newsom activated the state Office of Emergency Services operations center "to its highest level." "The state is coordinating mutual aid to local first responders," he said.
Disneyland in Orange County and Six Flags Magic Mountain in Santa Clarita closed their rides.
An NBA Summer League game in Las Vegas was stopped after the quake. Speakers over the court at the Thomas & Mack Center continued swaying more than 10 minutes after the quake.
In Los Angeles, the quake rattled Dodger Stadium in the fourth inning of the team's game against the San Diego Padres.
"Everyone was jumping over us to leave," said Daniel Earle, 52, of Playa del Rey, who was sitting with his wife in the stadium's reserve level.
"People were freaking out," he said. "There was a concession guy, and he actually was really cool because he was really calm. He's like, 'Relax. Tranquilo. Relax. Tranquilo,' and people were looking around." "My wife was holding us, like squeezing. I'm surprised my arm is still here. She was squeezing into it so hard," Earle said.
However, the game continued.
The quake came as communities in the Mojave Desert tallied damage and made emergency repairs to cracked roads and broken pipes from the earlier quake.
Hours earlier, seismologists had said that quake had been followed by more than 1,700 aftershocks and that they might continue for years.
Jones said aftershocks from the new main quake could occur for three years. Earlier Friday, Los Angeles had revealed plans to lower slightly the threshold for public alerts from its earthquake early warning app.
But officials said the change was in the works before the quake, which gave scientists at the California Institute of Technology's seismology lab 48 seconds of warning but did not trigger a public notification.
"Our goal is to alert people who might experience potentially damaging shaking, not just feel the shaking," said Robert de Groot, a spokesman for the USGS's ShakeAlert system, which is being developed for California, Oregon and Washington.
The West Coast ShakeAlert system has provided non-public earthquake notifications on a daily basis to many test users, including emergency agencies, industries, transportation systems and schools.
Late last year, the city of Los Angeles released a mobile app intended to provide ShakeAlert warnings for users within Los Angeles County.
The trigger threshold for LA's app required a magnitude 5 or greater and an estimate of level 4 on the separate Modified Mercali Intensity scale, the level at which there is potentially damaging shaking.
Although Thursday's quake was well above magnitude 5, the expected shaking for the Los Angeles area was level 3, de Groot said.
A revision of the magnitude threshold down to 4.5 was already underway, but the shaking intensity level would remain at 4. The rationale is to avoid numerous ShakeAlerts for small earthquakes that do not affect people.
"If people get saturated with these messages, it's going to make people not care as much," he said.

Mumbai (PTI): NCP (SP) MLA Rohit Pawar on Wednesday alleged that someone was trying to save VSR Ventures in connection with the plane crash that killed Maharashtra deputy chief minister Ajit Pawar, and claimed that the AAIB preliminary probe vindicated the doubts earlier raised by him.
He also accused VSR company of indulging in several grave lapses in the past.
The Learjet 45 aircraft, operated by VSR Ventures, crashed near the Baramati air strip in Pune district on January 28, killing Pawar and four others.
In its 22-page preliminary report on the VSR Venture's Learjet plane crash, the Aircraft Accident Investigation Bureau (AAIB) said the visibility at the time of the crash was below the required level. It also flagged about fading marks on the runway and presence of loose gravels on the runway surface.
Pawar said, "I am not against VSR or the Directorate General of Civil Aviation (DGCA). Ajitdada was travelling in a VSR aircraft. Unless we go into the depth of every aspect, we will not know the truth. But someone is trying to save this company. The doubts we had raised have been proven correct in the inquiry report."
He also claimed that the AAIB report contained discrepancies, including mentioning Baramati as a district, and questioned how seriously the probe had been conducted.
Pawar, who has been regularly holding press conferences to raise issues concerning the Baramati plane crash, also contested the report's conclusion that the aircraft hit trees before crashing.
"The report says the aircraft struck trees and then fell. But there are no trees at that spot. There is only a small bush which the aircraft did not even touch. What is stated in the report about hitting trees is incorrect," he said.
Pawar further alleged that VSR Ventures had displayed irresponsibility on multiple occasions, citing an incident involving the then chief minister Eknath Shinde's Davos visit on January 20, 2023.
He claimed that the aircraft carrying Shinde had entered Iranian and Iraqi airspace without overflight permission, following which fighter jets from the two countries allegedly warned of action, forcing a change in route from Bahrain to Zurich.
"There have been several such grave lapses by VSR," he said.
Pawar demanded to know from where VSR Ventures derived its "audacity", and sought details about its investors and officials, though he added that he was not personally concerned with who they were.
Drawing a comparison, he said the Central Bureau of Investigation (CBI) had taken over the probe into actor Sushant Singh Rajput's death within two days, whereas a month had passed since the Baramati crash without a similar action.
He claimed that VSR Ventures had two directors and three shareholders, and that there were eight common names across two related companies.
He further alleged that the owner of VSR was related to the Union Civil Aviation Minister and questioned why the company, though registered in Delhi, had made high-value investments in Jubilee Hills (upscale area in Hyderabad) at rates allegedly Rs 17 crore above the market price.
The MLA representing the Karjat-Jamkhed assembly constituency in Ahilyanagar district also raised concerns about the legal and institutional framework of the AAIB under the 2017 rules, claiming it was neither a statutory nor an autonomous body and remained answerable to the secretary and the minister, besides being attached to the DGCA.
"There is no independent investigative agency," he alleged.
