Camp Pendleton Fire Department Fighting 80-Acre Blaze

Military weapons drills sparked a brush fire that blackened scores of open acres on the grounds of Camp Pendleton Thursday, authorities said.

The blaze began spreading across training areas on the northern San Diego County Marine Corps installation about 10:30 a.m., according to the base's public information office.

By late afternoon, the flames had blackened more than 80 acres but had caused no injuries and was posing no structural threats, USMC officials said.

The fire started as a result of live-fire training.

Current assets on-hand include three brush trucks and one water tender.

There was no immediate threat to any of the surrounding communities of the base.
