A huge fire broke out at the Chevron oil refinery outside Los Angeles in the US state of California, with towering flames visible for miles.
Residents reported a massive fireball erupting amid a loud, extended roar around 9:30 p.m. Thursday, with orange flames and smoke plumes filling the sky.
Mark Rogers, 34, told the Los Angeles Times he was playing soccer at Aviation Park, a few miles from the Chevron plant, when the apparent explosion took place. “I thought we got nuked or something.”
Officials in El Segundo, California, issued a statement about 30 minutes after the incident, urging locals to take safety measures by staying indoors.
El Segundo is a beachside city located in the South Bay region, about a mile (1.6 kilometers) south of Los Angeles International Airport.
The cause of the blaze remains unclear, as neither the company nor the El Segundo police and fire departments have commented on the fire, which appeared to have erupted suddenly.
Local television and radio network CBS said firefighters were called to the refinery in Los Angeles County after reports of the explosion.

According to the company’s website, the refinery covers roughly 1.5 square miles (3.9 square kilometers) and has more than 1,100 miles (1,770 kilometers) of pipelines. It has been operating since 1911 and can refine up to 290,000 barrels of crude oil per day, including gasoline, jet, and diesel fuels.
This is not the first time refineries in the United States—particularly in the South Bay, home to several major oil facilities—have caught fire.
In 2022, it took firefighters two hours to put out a fire at the Chevron El Segundo facility.
In 2020, a fire at the Marathon Petroleum refinery in Carson, California, sent flames at least 100 feet into the air and sparked hours of concern.
