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.

Southern California Edison acknowledged Thursday that videos have suggested a possible link between the utility’s equipment and the devastating Eaton Fire in Los Angeles.

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

Southern California Edison (SCE), a subsidiary of Edison International , said on Thursday that it was probing whether its equipment was associated with the ignition of two Los Angeles-area wildfires this year.

Southern California Edison disclosed that its equipment might have sparked the Hurst Fire, which erupted during January’s deadly LA firestorm, the Associated Press reports. The Hurst Fire burned 1.25 square miles but caused no fatalities or structural damage.

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.

New regulatory filing shows power line surges, problems during high winds, including at a transmission tower near start of Hurst blaze in LA County.

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.
