The Eaton Fire began in Southern California Edison's service area on Tuesday afternoon, according to a statement from parent company Edison International.

The utility has notified the California Public Utilities Commission that it had received a number of notices, from attorneys representing insurance companies, to preserve evidence regarding the Eaton fire.

Despite questions around electrical equipment, the utility wrote to California regulators that no fire agency nor its own analysis suggests that it started the fire near Los Angeles.

More than 4 million people were left in the dark (and the smoke) on Wednesday as fires raged around Southern California.
