A powerful 7.1-magnitude earthquake swayed buildings and cracked streets and foundations in Southern California on Friday night, sending terrified residents into the streets a day after another quake hit.
The latest earthquake Friday struck 11 miles northeast of Ridgecrest, according to the US Geological Survey. It was five times bigger and 11 times stronger than Thursday’s 6.4 -magnitude earthquake, also centered near Ridgecrest, CNN Meteorologist Brandon Miller said.
There’s been an average of one aftershock per minute since Friday’s quake in the southern part of the state, according to the US Geological Survey website.
Gas leaks caused structure fires throughout Ridgecrest, residents reported water main breaks, and power and communications were out in some areas, according to Mark Ghilarducci, director of the Governors’ Office of Emergency Management.
Several injuries were reported, according to Kern County spokeswoman Megan Person.
About 130 residents from Bakersfield and Trona were staying in a temporary shelter, Person said.
“On behalf of all Californians, I offer my heartfelt support to those affected by tonight’s earthquake near Ridgecrest,” Gov. Gavin Newsom said Saturday.
The governor said he requested a presidential emergency declaration for assistance.
No power or water in San Bernardino town
The San Bernardino County Fire Department said it received multiple reports of damage as well from northwest communities.
“Homes shifted, foundation cracks, retaining walls down,” the department said. “One injury (minor) with firefighters treating patient.”
Trona, a town of 2,000 people, does not have power or water, San Bernardino County Fire spokesman Jeremy Kern told CNN. Workers had been restoring power from the initial earthquake when Friday’s disrupted power again.
Both earthquakes disrupted the main water system. Officials are bringing in water to residents and fire teams.
No injuries have been reported in the town.
It lasted longer than Thursday’s earthquake
Bakersfield resident Giovanna Gomez was at home with her family when their house swayed and the water in her pool overflowed. They ran outside.
“It was about a minute long,” she said. “Far larger than the one that (happened) yesterday. It was a smooth roll going back and forth.”
Bakersfield is in Kern County, about 110 miles from Ridgecrest. Donald Castle, who lives in Porterville, west of Ridgecrest, said his house shook for nearly 25 seconds.
“It was more of a shake than what we had on the Fourth. It lasted longer and was more rolling,” he said.
Calls for medical help
No reports of major gas leaks or fatalities have been made, Kern County Fire Department Chief David Witt said. But calls came in for ambulance and medical assistance.
In Los Angeles, about 150 miles south of Ridgecrest, residents felt the earth shake, but no reports of serious damage were made, Mayor Eric Garcetti said.
The Los Angeles County Fire Department reported no major damage, deaths or serious injuries, but said some wires were down and power was out in some locations.
Shaking felt in Mexico and Las Vegas
The shaking was felt as far away as Mexico and Las Vegas, according to the USGS.
The NBA Summer League game between the New Orleans Pelicans and the New York Knicks in Las Vegas was postponed Friday following reports of the quake. Scoreboards and speakers near the ceiling of the arena shook when the earthquake hit.
Quakes are part of an ongoing system
CalTech seismologist Lucy Jones said Friday both earthquakes are part of an ongoing sequence of a “very energetic system.”
The latest 7.1-magnitude earthquake was the mainshock, while Thursday’s 6.4-magnitude quake was a foreshock, according to Jones.
In addition to being bigger, Miller said it released more than 11 times the amount of energy than the 6.4 one.
More earthquakes are possible. Newsom said he has activated the state emergency operation center to its highest level.
“The state is coordinating mutual aid to local first responders,” he tweeted Friday night.
