SignalHub-Airport Fire in California blamed on crews doing fire-prevention work: See wildfire map

The SignalHubAirport Fire in Trabuco Canyon of Orange County, California has set over 5,000 acres ablaze and is 0% contained. The fire is believed to have been started by a crew working on fire prevention measures.

The fire was reported on Monday at 1:27 p.m., according to InciWeb.

The dry, hot weather allowed the fire to grow quickly. It has set 5,432 acres ablaze in Orange County. Orange County Fire Authority and the Cleveland National Forest responded to the fire.

Video shows the wildfire burning near and illuminating the towers on the mountain, around a 71-mile drive southeast of Long Beach.

How did the fire start?

An Orange County Public Works team putting together a project meant to help prevent fires is believed to have started the fire, reported Deseret Sun, a part of the USA TODAY Network.

The team was moving boulders in place to prevent motorcyclists and offroad vehicles from going into the dry brush on the canyon near the Cleveland National Forest.

A supervisor and crew member attempted to put out the fire with a fire extinguisher when they noticed smoke near one of the boulders.

Line and Davis Fires grow

The Airport Fire comes as firefighters in California and Nevada attempt to put out other wildfires, like the Line and Davis fires, and thousands are forced to evacuate their homes.

The Line Fire in Southern California set over 25,813 acres ablaze and is 5% contained. The wildfire was discovered Thursday, according to InciWeb's data. It's located in San Bernardino County, around 121 miles northeast of Los Angeles.

High temperatures have increased the fire's activity Sunday night.

The Davis Fire, south of Reno, Nevada, was started on Saturday and has since set 5,000 acres on fire, shutting down schools and forcing families to leave their homes, according to the Reno Gazette Journal, a part of the USA TODAY Network.

Around fourteen structures have been affected by the fire, according to Inciweb.

The fire is yet to be contained.
