A series of three earthquakes trembled Southern California today, Monday, March 11, 2013.
The U.S. Geological Survey reported one earthquake measuring at a 4.7 magnitude, and centered 14 miles southwest of La Quinta, Calif., and 23 miles south of Palm Springs, Calif., but was felt over a wide area of Southern California. The quake was at a depth of about eight miles, according to the USGS.
According to various news reports, the earthquakes could be felt in San Diego, in parts of Orange County, and in parts of Los Angeles. The magnitude-4.7 earthquake was the largest centered in the greater Los Angeles area since 2010, officials said.

Monday’s earthquake occurred on the San Jacinto Fault, which one of the most active faults in California, said Tom Rockwell, a seismologist at San Diego State University.
The California earthquakes struck shortly before 10 a.m. while they were reported at a magnitude of 5.2, they were downgraded quickly by seismologists. Quakes of that size, typically cause little damage, are relatively common in Southern California.
“It’s extremely unlikely that there’s damage from this earthquake,” said Lucy Jones, a seismologist with the U.S. Geological Survey in Pasadena. “At most, there might be some places where things were thrown off shelves, but that might be the extent of the damage.”
The Riverside County Fire Department received a few calls from people who felt the earthquake, but no reports of damage, said department spokeswoman Jody Hagemann.
“It was a pretty good shake up here.” said Capt. Daniel Heiser of the Riverside County Fire Department.
The Los Angeles Fire Department said it was assessing the situation but reported no immediate damage.
