The County of Los Angeles and city of Pasadena filed separate lawsuits against Southern California Edison Wednesday over the Eaton Fire, alleging the utility's electrical equipment caused the deadly wildfire.

The Eaton Fire killed 17 people as it devastated the community of Altadena, burning through more than 14,000 acres and damaging and destroying thousands of structures after breaking out on Jan. 7. The suit filed by LA County alleges the blaze sparked during a forecasted high wind event, below a transmission tower carrying high-voltage power lines and "electrical equipment designed, owned, managed, and maintained by EDISON, resulting in fire to the surrounding vegetation," the court filings read. According to the lawsuit, those allegations are backed by evidence from photos, video footage and witness statements.

Another separate lawsuit was also filed Wednesday against SoCal Edison by the city of Pasadena, which alleges the utility's electrical equipment caused the devastating blaze and led to widespread damage to the city's infrastructure.

CBS News Los Angeles has reached out to SoCal Edison for its response to the litigation.
