A wildfire in the US state of California that is burning through coastal wilderness has nearly doubled in size since Friday morning, growing to more than 28 square miles (72 square kilometres), fire officials said.
Aerials showed the extent of the blaze as firefighters battled to save homes in Ventura County, in the south of the state.
A Ventura County fire spokesman says the 18,000-acre fire is burning new fuel in mostly unpopulated canyons.
He said fire officials have manage to contain 20 percent of the blaze.
The fire was estimated to have burned about 15 square miles (38 square kilometres) as of early Friday morning.
The fire erupted on Thursday in the Camarillo area, threatening as many as 4,000 homes but only damaging 15.
No injuries have been reported.
After burning to the Pacific Ocean, a shift in winds caused the flames to reverse course and burn inland.
"180 degree wind shift is a big concern for operations, and so that today is the big issue. In addition to all the infrastructure that we still have to protect," said Steve Seltzner, US Forest Service Division Chief.
Some homes were damaged but no homes have been lost, mostly due to the efforts of firefighters.
"It came pretty close," said homeowner Shane Poindexter.
"These firemen did a tremendous job, so very, very thankful for them," he added.
