A magnitude-4.0 earthquake struck the Big Bear Lake area earlier Wednesday morning in California, sending aftershocks that could be felt throughout Southern California, according to the U.S. Geological Survey.

The quake, which was initially reported with a magnitude of 4.5, hit at approximately 9:10 a.m. local time with a depth of 7 miles. It was centered 7 miles southeast of Big Bear Lake and 8 miles south of Big Bear City, USGS reported, according to CW California affiliate KTLA.

USGS seismologist Lucy Jones was at the Southern California Earthquake Center's annual meeting in Palm Springs when the quake hit. She took to Twitter to say the temblor was near the San Andreas fault, but preliminary information indicates that it wasn't of the the San Andreas fault type.

Weak shaking was reported in Yucaipa, Cabazon, Redlands, Loma Linda, Riverside and Palm Springs.

The earthquake was downgraded to 4.0 just a few seconds after it struck, with Jones once again tweeting about the quake, according to the Los Angeles Times.

There were no immediate reports of damage or injuries, according to the San Bernardino County Fire Department, NBC Los Angeles reported.
