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.

Containment measures the percentage of a fire's perimeter that firefighters have under control. Parts of the fire's interior may still be burning.

A California utility said Thursday its equipment likely sparked a 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.

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

The utility company said its equipment may have 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.
