Lawyers with LA Fire Justice say the Eaton Fire, which destroyed thousands of homes in Altadena and Pasadena, was "preventable," blaming the fire on Southern California Edison's equipment.

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