A magnitude 4.3 earthquake struck in Carson at 7:58 p.m. Friday evening, the U.S. Geological Survey reported, but it did not cause significant damage or injuries.
There was no major infrastructure damage observed by the Los Angeles County and Los Angeles fire departments. There have been no deaths or serious injuries that can be attributed to the earthquake, according to the LAFD.
The earthquake was reported felt from Ventura County to Orange County.
The earthquake was west of the Newport-Inglewood fault by slightly more than one mile, according to seismologist Lucy Jones.
The depth was 14 kilometers, about 8.5 miles.
Jones told KCAL9 it was “a pretty ordinary earthquake.”
“This size happens on average somewhere in Southern California every couple of months,” Jones told KCAL9. “When it happens to be in the middle of the Los Angeles basin then a lot more people feel it and it becomes bigger news.”
The earthquake felt like a car hitting the building, a firefighter at a Carson station told KCAL9.
The earthquake caused the Marathon Petroleum refinery in Carson to lose power, Jamal Kheiry, a spokesman for the company told the Los Angeles Times.
The refinery began conducting flaring to burn off excess gases which lit up the night sky and prompted concern among residents in Carson and beyond, The Times reported.
“Flares are safety devices and the flares are functioning as intended, Kheiry told The Times in an email. “There are no injuries or off-site impact.”
Los Angeles County firefighters were at first summoned to the refinery about 8:02 p.m., but refinery officials then called and canceled.
Inspectors from the South Coast Air Quality Management District went to multiple refineries, the district reported.
Community monitors showed no elevated levels of toxic compounds. Fenceline monitors at the Marathon Refinery showed slightly elevated levels of hydrogen sulfide, according to the district, which said it would continue to monitor the situation.
An earthquake with a 3.0 magnitude struck Carson at 11:06 p.m., the U.S. Geological Survey reported.
The initial earthquake’s preliminary magnitude was 4.4 and later downgraded.
