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

More than 40 lawsuits have been filed against Southern California Edison, as law firms launch their own investigations into the cause of the Eaton fire.

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.
