A minor earthquake shook the City of Angels on Friday night, according to the U.S. Geological Survey.
The agency reported a magnitude of 4.3 on the Richter scale with an epicenter in Carson, Calif., which is Los Angeles County.
The 15-second-long temblor caused a Marathon Petroleum refinery to lose power and resort to dramatic flaring, scaring locals, the Los Angeles Times reported.
There are about five quakes per year that rank between 4.0 and 5.0 on the Richter scale, the paper said.
There were no immediate reported of injuries or damage, the Associated Press reported.
