The Nixon Fire, which has burned more than 5,200 acres, was started by an electrical panel, fire officials said last week.

“CAL FIRE Peace Officers, after an origin and cause investigation, determined that the cause of the fire was electrical and caused by a privately owned electrical panel,” a statement posted to social media said.

The fire was first reported July 29 at about 12:30 p.m. at the intersection of Tule Valley Road and Richard Nixon Boulevard in the unincorporated community of Aguanga and quickly grew to 4,500 acres by the following afternoon, prompting widespread evacuations.

“Currently there are approximately 1,157 structures impacted by the evacuation warning and 979 structures impacted by the evacuation order,” Tawny Castro, senior public information specialist, said in a July 29 update posted to social media.

We would like to thank the community for their cooperation during this time.”

At least one residential structure has been destroyed and four other structures have been damaged. There have been no injuries reported as a result of the fire.
