EL SEGUNDO, Calif. (KABC) -- Crews extinguished a massive fire that erupted at a Chevron oil refinery in El Segundo, which sent up large flames and plumes of smoke into the air.
The fire broke out around 9 p.m. Thursday and could be seen for miles across the South Bay. Officials said there was no threat to the public.
"All refinery personnel and contractors have been accounted for and there are no injuries," Allison Cook, a Chevron spokesperson, said in a statement.
The refinery is the largest oil-producing site on the West Coast, and it isn't the first explosion it has seen.
It was not immediately clear what caused Thursday's blaze.
Chevron's El Segundo refinery covers roughly 1.5 square miles and has more than 1,100 miles of pipelines, according to the company's website.
The refinery, which has been in operation since 1911, can refine up to 290,000 barrels of crude oil per day, including gasoline, jet and diesel fuels, according to the company's website.
The Associated Press contributed to this report.
As fire crews rushed to battle the flames, many El Segundo residents recalled hearing a loud blast and even "a rumble" when the blaze erupted.
"It sounded a little bit like someone was inside my apartment, and pretty much immediately started getting texts," said one resident.
It was not immediately clear what caused the fire or whether anyone had been injured.
A shelter-in-place order was issued for Manhattan Beach's Tree Section.
According to Alert SouthBay, people living in zones MB-001 and MB-009 were asked to stay in doors for the next three hours.
People who were at the Top Golf in El Segundo late Thursday night captured the massive fire on video.
One video, which appeared to be taken just after the blaze erupted, showed people running through the parking lot to get to their vehicles.
No injuries were reported.
