A magnitude 4.1 earthquake hit the Corona area of Riverside County at 1:49 p.m. (GMT-7), May 1, according to the United States Geological Survey (USGS), Report informs CBS News.
The shaker could be felt over a wide area from Orange County and West Los Angeles, to the KCAL News studios in Studio City.
The earthquake, which was initially reported to be magnitude 4.5, originated 1.5 km below ground.
The earthquake was located near the Whittier fault, and that's most likely the source of this earthquake, according to Dr. Lucy Jones. "But, you've really got to be up over a magnitude 5 before you can definitively say which fault something is on."
According to Dr. Lucy Jones, there have been no recorded aftershocks, however there have been roughly around a dozen foreshocks in the area which have occurred over the past two days.
