Cal Fire report; Sagging PG&E power lines caused Cascade Fire

Cal Fire announced on Tuesday that after an investigation into the cause of the October, 2017 Cascade Fire, it was determined that the fire was caused by sagging power lines owned by PG&E.

The Cascade Fire started on October 8, 2017 in Yuba County, burned 9,889 acres, took the lives of four civilians and injured one firefighter, according to Cal Fire.

The report determined that high winds, in combination with the sagging power lines, caused the lines to touch each other, creating an electrical arc and depositing hot material onto the ground, which caused the fire.

According to Cal Fire, the term for this type of situation is called a "line slap," meaning when two power lines come into contact with each other.

The Cal Fire report has been given to the Yuba County District Attorney.
