Two days of intermittent shaking punctuated by the most significant earthquakes California has seen in years have left residents “scared to death.”
Warnings that Southern California’s July Fourth earthquake could be followed by a more intense seismic event came true Friday night when a 7.1-magnitude earthquake struck at 8:19 p.m. local time about 125 miles northeast of Los Angeles.
The epicenter was in a remote area about 10 miles northeast of Ridgecrest, Calif., a city of 28,000 that had already declared a state of emergency after a nearby 6.4-magnitude temblor hit on Thursday. Its residents, startled from the first quake, were jolted into a new level of anxiety by Friday’s severe follow-up, and a persistent “swarm” of aftershocks is expected to torment them for days, if not weeks.
“We’re pretty much scared to death,” said Nancy Pace, 66, who runs the Bake My Day pastry business and feared that another large quake could hit at “any second.”

Pace and her roommate “were getting slammed back and forth between the walls” during the earthquake Friday night — one of the biggest in California history — and had been so afraid of her home collapsing from a subsequent quake that they slept outside on air mattresses along with their neighbors. But it was far from a restful sleep.
“Every time I tried to doze off we had another earthquake,” she said.
Friday night’s earthquake was 11 times stronger than that original disturbance, and U.S. Geological Survey geophysicist Paul Caruso said that the region could expect to feel stronger aftershocks as a result. It was part of a “swarm” of earthquakes that had hit the region, located west of the Mojave Desert. Because it was larger than the 6.4 earthquake that struck Thursday, Friday’s quake would be considered the main shock, Caruso said.

Southern California could experience another sizable earthquake over the next week, seismologists said Saturday.
The U.S. Geological Survey has calculated a 27% probability the region will be hit by a magnitude 6 or greater quake in the coming days, according to Caltech seismologist Egill Hauksson,
“That probability is over the next week, but it is mostly packed into the hours and days after the main shock,” Caltech seismologist Doug Given said.
In other words, the probability that we will experience another earthquake of magnitude 6 or higher is dropping by the minute, he said.
“Every minute that ticks by, it becomes less likely,” he said.
The heightened seismic activity comes in the aftermath of a 7.1 magnitude quake that hit near the town of Ridgecrest, about 125 miles northeast of Los Angeles, on Friday night. That was preceded by a 6.4 magnitude earthquake in the same area the morning of the Fourth of July. Scientists are now calling that a foreshock.
Since the Fourth, Caltech seismologists have detected at least 3,000 smaller earthquakes.
Those include 340 earthquakes with a magnitude greater than 3, 52 with a magnitude greater than 4, and six with a magnitude greater than 5, Hauksson said Saturday.
In total, this earthquake sequence is expected to generate about 34,000 aftershocks with a magnitude 1 or greater over the next six months, he said.
This week’s earthquakes were the strongest to hit the area in 20 years. No deaths or major injuries have been reported, but homes and roadways were damaged, particularly in the Ridgecrest area.
Gov. Gavin Newsom has requested a presidential emergency declaration for the affected regions.
With the fear of more aftershocks, Jimmy and Jackie Roberts are taking no chances of staying in their home.
The couple was assembling a 20-foot-by-10-foor canopy at their home on Desert Candles Street. They last used the blue canopy at their wedding 10 years ago and plan to put a tent and air conditioner under it.
“We’re staying in it for the next three days,” she said. “We have to keep our three dogs and four birds safe.”
She said the couple and many neighbors slept in their cars last night on the street. “We were all out there,” she said. “We were afraid.” Her biggest fear, she said, is another quake will hit and people will run out of water in the 90-degree temperatures. She also expects more neighbors to sleep in tents or cars until dangers clear. “My other neighbor is buying a camper today,” she added.
Ridgecrest Mayor Peggy Breeden said she encourages residents to take safety precautions over the next few days until the seismic activity subsides. She said the town shouldn’t suffer any long-term consequences from the last several days. She doesn’t believe residents will flee to other cities.
“We’re used to this,” she said after a news conference. “We live in the earthquake capital of the world, so I’m told. Our people are strong.”
