California utility company Southern California Edison on Thursday said its equipment “may be associated with” the ignition of the Hurst Fire, which burned alongside the Eaton and Palisades fires during January’s Los Angeles firestorms.

Southern California Edison is looking into whether its equipment is tied to the Eaton and Hurst Fires, its parent company said, though the cause has not been officially determined.

A California utility says its equipment likely sparked a small wildfire in Los Angeles that broke out the same day as two massive blazes in the area killed at least 29 people and destroyed thousands of homes.
