Four disastrous wildfires were still burning across Los Angeles and Ventura counties in southern California on Tuesday, but it’s not yet clear what started the fires—as government officials, lawyers and experts weigh theories like electrical issues, embers from older fires and arson.
The Palisades Fire and Eaton Fire both broke out on Jan. 7 and grew to more than 23,000 and 14,000 acres, respectively, destroying thousands of structures and leading to more than 100,000 evacuations throughout Los Angeles.
Several smaller fires—including the Hurst Fire and Auto Fire, which were both still active as of Tuesday—broke out after the Palisades and Eaton fires, and led to more evacuations.
