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.

Southern California Edison said video evidence had led it to look more broadly at whether its equipment might have been the cause of the deadly blaze.

Edison International Inc.‘s Southern California utility equipment created a powerful electric arc above Altadena, Calif., that ignited the deadly Eaton fire, a law firm suing the utility says, citing new video footage from a nearby gas station.
