A doorstep video released by The Associated Press and others shows a fire at the base of a hilltop electrical pylon in Altadena, California—what residents say was the origin of the Eaton fire. Within minutes, high winds had carried the fire across the neighborhood and the sky was soon lit red with intense burning.

The court filings blame the utility for the fire despite the fact that the blaze's cause is still under investigation.

Edison International — the parent company of the utility Southern California Edison — has seen its stock remain under pressure as lawsuits begin over its potential role in the fires that have ravaged parts of Southern California.
