The Eaton Fire was a highly-destructive wildfire in Los Angeles County, Southern California. The fire began on the evening of January 7, 2025, in the Eaton Canyon in the San Gabriel Mountains, and was driven by powerful Santa Ana winds into foothill communities, particularly Altadena. The fire killed at least 17 people and destroyed more than 9,000 buildings, becoming the fifth deadliest and the second most destructive wildfire in the history of the state of California. The cause of the fire is under investigation; news reports and lawsuits have focused on the possible involvement of power lines operated by electrical utility Southern California Edison. The fire was fully contained on January 31 after burning for 24 days.
