A massive explosion at an oil refinery in Los Angeles triggered a huge fireball that sent shockwaves through the city. 

The blast took place just outside LAX airport and was seen for miles across the city after it ignited at the Chevron refinery in El Segundo, police said.

Firefighters arrived to the scene at around 9:35pm local time, several minutes after people in surrounding areas reported hearing a loud blast.

Authorities said they have not received reports of any injuries. No evacuation orders were in place early Friday, but residents were instructed to stay indoors and shut their windows.

The El Segundo neighborhood is located just south of LAX. Los Angeles mayor Karen Bass assured travelers that there was 'no known impact' to the international hub.

Officials also told the Daily Mail that flights weren't currently affected.

El Segundo Mayor Chris Pimentel praised the quick response to the fire while saying he was 'very concerned' by the incident.

'We were able to respond to the Chevron fire immediately, our station is about a .25 miles away from the gates of Chevron,' Pimentel said. 'Obviously, we are very concerned, and there is a lot of investigative work to be done to see what has happened.'

The night sky could be seen engulfed by bright orange flames with smoke billowing toward the sky as witnesses recounted hearing a 'sudden steady roar.'

One captivating image posted on social media showed firefighters atop a ladder spraying water down on the flames, which were several stories high at that point.

In one video, patrons at a nearby Top Golf were transfixed by the fire, with many of them recording it with their phones.

Their curiosity turned into outright terror once they realized just how huge the blaze was, leading them to run into the parking lot to get to their cars.

The Torrance Police Department told the Daily Mail units are currently at the facility, which spans two-square-miles and supplies more than 40 percent of jet fuel and more than 20 percent of motor vehicle fuel across Southern California.
