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.

The utility company said its equipment likely caused the fire but that an investigation is continuing and that they are cooperating with authorities.

SoCal Edison’s latest report to the California Public Utilities Commission includes new information about the Eaton Fire in Altadena and Hurst Fire in Sylmar.
