Eaton Fire in Altadena sparked by SoCal Edison electric tower, probe finds
The department said an 18-month investigation concluded that electrical arcing on an out-of-service Southern California Edison tower was responsible.
The Los Angeles County Fire Department concluded on Tuesday that an 18-month investigation into the Eaton Fire found electrical arcing on an out-of-service transmission tower to be the cause. The arcing events ejected hot metal particles onto receptive fuel beds of dry vegetation below the towers, located on a ridge above the Eaton Wash.
Fire Chief Anthony C. Marrone expressed the deep impact of the tragedy but emphasized the focus on assisting residents to rebuild. The investigation, conducted jointly by the LACFD's Arson Fire Investigation Unit and Cal Fire, analyzed Southern California Edison's electrical and mechanical systems, as well as photographic and video evidence.
