SAN JOSE -- Cal Fire officials are investigating the cause of a two-alarm blaze Thursday that destroyed two homes and scorched a hillside west of Mt. Hamilton.

The fire completely destroyed two homes in the 13000 block of Clayton Road and sent plumes of smoke into the sky. Smoke from the fire was visible up and down Highway 101 in South San Jose, as well as surrounding city streets.

The blaze was first reported at 4:22 p.m. as a brush fire. Arriving crews found a shed fully engulfed in flames and saw the fire had spread to nearby brush, according to San Jose fire Capt. Cleo Doss.

The blaze eventually spread to two homes.

There were no reports of injuries. Witnesses said they saw a person running from one of the homes before crews arrived on the scene.

Early Thursday evening, piles of trash still smoldered near the home. Crews from CalFire were on the scene, assisting San Jose firefighters in putting out spot fires and cleaning up the scene.

Doss said that the fire may have been stopped from spreading to other nearby homes because of good fire prevention techniques by the homeowners; grass around the homes and along the hilltop had been cut low, which helped crews move more quickly in confronting the flames.

Cal Fire Batallion Chief Brandon Leitzke said the cause of the fire was still under investigation and may take a few days to complete.
