Huge fire engulfs Los Angeles oil refinery as blazing inferno can be seen for miles

The cause of the fire at the oil refinery, which supplies jet fuel for Los Angeles International Airport (LAX), was not immediately clear.

Los Angeles Mayor, Karen Bass, assured travellers that there is "no know impact" to the airport.

Fire chiefs said there was no reports of injury from the scene of the fire.

Chevron spokeswoman, Allison Cook, said all staff and contractors at the site had been accounted for.

The blaze continued to burn after midnight.

"Chevron fire department personnel, including emergency responders from the cities of El Segundo and Manhattan Beach are actively responding to an isolated fire inside the Chevron El Segundo Refinery," Ms Cook said.

"All refinery personnel and contractors have been accounted for and there are no injuries."

Local officials said no evacuation orders were issued for nearby residents.

Those living in Manhattan Beach, located southwest of the refinery, were however told to shelter-in-place until 2am.

Los Angeles residents posted various videos of the fire to social media, saying they were stunned by the noise of the explosion.

The fireball when the fire erupted turned the sky orange in the western Los Angeles area, as did the refinery's safety flare, which was set off due to the blaze.

Resident Mark Rogers was playing football a few miles away when he heard the explosion.

"I thought we got nuked or something," he told the Los Angeles Times.

The El Segundo sit is Chevron's second biggest refinery in the United States and produces about 40 per cent of southern California’s jet fuel and 20 per cent of its gasoline.

Another isolated fire took place at the site in December, 2022, but was quickly extinguished.
