Edison International’s utility said it is looking at whether a decommissioned power line started the Eaton wildfire as part of a probe into the cause of the blaze that razed more than 9,000 structures near Los Angeles.

The utility has noted multiple irregularities, but maintains there is no evidence its equipment sparked the destructive Eaton fire.

Southern California Edison is examining the role of an idle transmission line near the area where the fire started.
