A new investigation by the Los Angeles County Fire Department concludes the deadly Eaton Fire was sparked by an out-of-service Southern California Edison transmission tower that generated electrical arcing during dangerous fire weather.
According to the report, the tower was no longer carrying electricity but remained energized, allowing an electrical arc to ignite dry vegetation beneath the structure. Fueled by powerful Santa Ana winds, the flames quickly exploded into one of Southern California’s most destructive wildfires.
The Eaton Fire killed 19 people, destroyed more than 9,400 homes and businesses, damaged thousands of additional structures, and burned roughly 22 square miles across Altadena and surrounding communities. The disaster has resulted in billions of dollars in losses and prompted dozens of lawsuits against Southern California Edison.
The utility says it has received the county’s findings and is reviewing the report but has not accepted responsibility for the fire. Edison has previously argued that other factors—including evacuation challenges and water system failures—contributed to the scale of the destruction.
The county’s findings are expected to play a significant role in ongoing litigation and could shape future wildfire prevention policies involving California’s electrical grid.
