Security video from a gas station in Altadena offers new evidence that Southern California Edison electrical equipment may have started the deadly Eaton Fire.

A video shows arcing at a Southern California Edison tower, then a fire at the tower's base, suggesting the Eaton fire may have been caused by electrical equipment.

Edison International Inc.‘s Southern California utility equipment created a powerful electric arc above Altadena, Calif., that ignited the deadly Eaton fire, a law firm suing the utility says, citing new video footage from a nearby gas station.

The utility company maintained that the current increase remained within the design limits and did not trigger system protection on these lines.

Edison says current increase "remained within the design limits and operating criteria" for the circuits and "did not trigger system protection on these lines."

High-voltage power lines saw a temporary surge in electrical current in the area where the deadly Eaton Fire is believed to have started, Southern California Edison said.

Attorneys who claim malfunctioning Southern California Edison equipment caused the deadly, destructive Eaton Fire on Monday released video they believe shows sparks from Edison power lines igniting the blaze.
