A massive refinery fire in Southern California that began with a powerful explosion late Thursday night has now been fully contained, but not before thick clouds of smoke billowed into the sky and forced nearby residents to shelter indoors for safety.

Authorities confirmed that fire crews worked through the night to extinguish the blaze, which originated at one of the region’s key fuel production facilities. Although the flames are now out, attention has shifted to the potential economic ripple effects—especially on gasoline prices across California.

With the refinery temporarily shut down and damage assessments underway, many drivers are wondering whether this incident could trigger a short-term increase in gas prices. The state already has some of the highest fuel costs in the nation, and supply disruptions often lead to quick price jumps at the pump.
