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 is looking at whether a power line retired in 1971 started the Eaton wildfire as part of a probe into the cause of the blaze that razed more than 9,000 structures.
