High winds pushing power lines sparked 2017's deadly Thomas Fire, California's second largest wildfire, officials said Wednesday.
The wind caused power lines to touch, creating an electrical arc that shot out hot, burning molten material onto the ground, according to a news release from the Ventura County Fire Department.
The Thomas Fire, which started Dec. 4, 2017, burned over 40 days, crossed two counties, caused two deaths, destroyed more than 1,000 structures and charred more than 282,000 acres.
