5.2 earthquake shakes Southern California awake Friday video

A magnitude 5.2 earthquake near the San Jacinto fault shook Southern California early Friday, jolting residents awake.

The earthquake occurred at 1:04 a.m., according to early information from the United States Geological Survey. Initial incomplete data had suggested two quakes of roughly the same size shook within a minute.

The temblor was centered in Anza-Borrego Desert State Park.

Minutes later, there were two aftershocks that measured at 3.0 and 3.5. Dozens of small aftershocks followed as well, as are to be expected following a decent-sized quake.

There were no immediate reports of damage or injuries.

All earthquakes were centered about 15.5 miles southwest of La Quinta.

The San Jacinto fault is one of Southern California's most active, seismologist Lucy Jones pointed out on Twitter following the quakes on Friday. She also calmed some nerves when saying quakes on the San Jacinto fault have never triggered an earthquake on the San Andreas fault, which is more than 150 years overdue on its southern end that starts at the Salton Sea and heads northeast through the Coachella Valley.

Within an hour and 20 minutes, there were seven aftershocks in the same general area. The strongest were magnitude-3.5 shakers at 1:06 a.m. and at 1:33 a.m. with roughly the same epicenter as the main quake but at depths of 6.7 miles and 6.2 miles, respectively, according to the USGS. The most recent was a 3.5- magnitude reported in the Borrego Springs area at 4:14 a.m.

“Every earthquake has a 5 percent (chance) of triggering an aftershock that is bigger than itself – always within a few miles of location of the first earthquake,” Jones wrote.

Many who experienced the temblor immediately took to social media.

"Oh dear Lord that's the worst freakin' earthquake I've felt in the 7 years we've lived here. Lasted too long! Can't tell if it's still shaking or I'm still shaking," Helen Holdun of Palm Springs wrote on The Desert Sun's Facebook page. "Neighbors actually gathered outside. My neighbors don't gather often."

Victoria Garcia wrote: "I felt it in Palm Desert! Things fell in the kitchen, cabinets opened and pictures moved on the walls!"

In La Quinta, about 60 miles from Borrego Springs, some reported items shaken from shelves and the walls, but fire officials said there were no reports of major damage.

"We've had no calls," Capt. Anthony Khatami at Station 32 said.

Sara Alonzo of Indio posted a photo from inside the Walmart in La Quinta, showing items knocked off store shelves by the quake.

"I was in Palm Desert when the earthquake happened but then after that I stopped by Walmart at La Quinta and all the employees were outside when I got there and they had a couple of aisles closed," she told The Desert Sun.

Anthony Montenello, a server at Louise's Pantry in La Quinta, said nothing was out of place when he arrived at the restaurant on Washington Street Friday morning.

"I walked in here and everything's fine," he said.

La Quinta Mayor Linda Evans, who lives in the cove, said "It was pretty loud and strong, but short."

Friday's noteworthy quake comes nearly 24 years after the magnitude-7.3 Landers quake that shook the high desert and Southern California on June 28, 1992.
