“VCFD Determines Cause of the Thomas Fire,” Ventura County Fire Department, 13 March 2019, https://vcfd.org/news/vcfd-determines-cause-of-the-thomas-fire/.

This document is a report published by the Ventura County Fire Department. The post also outlines how nearly two years after the Thomas Fire burned through Ventura and Santa Barbara Counties, an investigation, headed by the Ventura County Fire Department, concluded that both of the fire’s ignition sites were “sparked” by Southern California Edison’s power lines. The lines came into contact (“phase to phase”) during high winds, resulting in an arc that “deposited hot, burning or molten material onto the ground, in a receptive fuel bed, causing the fire.” This report will, overall, function to provide participants with basic background information on the Thomas Fire.
