Incident Overview
On the night of October 2, 2025, a significant fire broke out at the Chevron refinery in El Segundo, Los Angeles County, following an explosion reported around 9:30 p.m. local time. Witnesses described the explosion as feeling like an earthquake, with flames visible for miles. The El Segundo Police Department and local fire departments responded promptly, and by 10:30 p.m., officials reported that the fire had been largely contained to one area of the facility.
Emergency Response and Containment
The Chevron refinery, which has its own fire department, received assistance from the El Segundo Fire Department and other regional agencies. Los Angeles County Supervisor Holly Mitchell confirmed that there were no injuries reported and that all personnel had been accounted for. Mayor Chris Pimentel stated that the fire was contained to the refinery grounds, and there was no immediate threat to the surrounding communities. Residents were advised to stay indoors and close windows to mitigate smoke exposure.
Air Quality Concerns
Officials from the South Coast Air Quality Management District monitored air quality conditions in the area. Initial reports indicated no elevated levels of particulate matter or air toxins, although there were some elevated levels of volatile organic compounds (VOCs). Authorities cautioned that air quality could change as the situation developed.
Historical Context and Significance
The Chevron El Segundo refinery, operational since 1911, is the largest oil refinery on the West Coast, processing up to 290,000 barrels of crude oil daily. It supplies over 40% of jet fuel and 20% of motor vehicle fuel in Southern California. The facility spans approximately 1,000 acres and employs around 1,000 workers, with an additional 1,000 contractors on-site daily. Past incidents at the refinery include a fire in 2022 that took two hours to extinguish and another in 2017 caused by a pump failure.
Official Statements
California Governor Gavin Newsom's office stated that they were coordinating with local and state agencies to ensure public safety. Mayor Karen Bass confirmed that there was no known impact on operations at Los Angeles International Airport (LAX), located just south of the refinery.
Eyewitness Accounts
Residents and bystanders reported feeling the explosion and witnessing the subsequent fireball. Mark Rogers, who was playing soccer nearby, remarked, “I thought we got nuked or something.” Another resident, Kevin Mohr, described seeing flames reaching 300 feet high and expressed uncertainty about whether a plane had crashed or if there had been an earthquake.
Conclusion
As of now, the situation remains under control, with ongoing assessments of the fire's cause and its impact on the community. Local authorities continue to monitor air quality and provide updates as necessary. The Chevron refinery's history of incidents raises ongoing concerns regarding safety and emergency preparedness in the region.
