Firefighters battle large blaze at Chevron refinery in Southern California

Overnight, a massive explosion at a Chevron refinery, sending a massive fireball into the night sky. Firefighters rushing to the scene in El Segundo, California around 9.30 last night, trying to tackle that gigantic blaze. Several fires burning within the facility. We have heavy flames showing from the refinery. I'll need a truck company with a master train to respond to this. Towering flames and billowing smoke turning the night sky red. The inferno could be seen for miles. That blast so strong, residents say they thought it was an earthquake or a plane crash. Yeah, it was a terrible explosion. Very loud, shook the house more than any earthquake ever before. Out of control, for sure. And we didn't know what was going to happen next. Those residents were told to stay indoors and shelter in place after concerns about the air quality. There are several massive flames coming from the refinery. That right there appears to be the epicenter of this explosion that occurred. At times, it seemed like the fire was under control, and then it would flare back up again. The smoke traveling to nearby LAX, blanketing the planes on the tarmac. That oil refinery is the largest on the West Coast, spanning two square miles. It supplies more than 40% of the jet fuel and more than 20% of the motor vehicle fuel for Southern California. Not yet clear what caused this explosion, but no injuries have been reported.
