California declared a state of emergency yesterday as firefighters struggled to tackle a forest fire that had destroyed more than 200 buildings in less than a day and forced about 1000 people to flee neighbourhoods near the edge of Lake Tahoe.

The emergency declaration was the first step in requesting emergency federal assistance to fight the fire, which rained ash on the pristine lake and darkened the sky.

"The circumstances of this wildfire, by reason of their magnitude, are beyond the control of the services, personnel, equipment and facilities of any single county," said deputy governor John Garamendi, who signed the declaration while governor Arnold Schwarzenegger was in Europe.

The fire, believed to be caused by human activity, had charred nearly 2500 acres - nearly four square miles - since it started on Sunday afternoon. No injury was reported. The state Office of Emergency Services said 165 houses and 75 outbuildings had been destroyed.

The blaze was less than 10% contained yesterday, said Kevin House of the El Dorado County Sheriff's Department.

"This is far and above the biggest disaster that has happened in this community," House said.

The fire spread northward, enveloping hundreds of acres of unpopulated mountainside, and fire officials warned that afternoon wind could turn the flames toward the east and threaten hundreds more homes.

The number of firefighters battling the blaze was nearly doubled yesterday to more than 700. However, air tankers and helicopters were grounded by smoke that cut visibility.

Fire officials said they had two days to get the fire under control because high wind and low humidity are forecast for tomorrow. "We have a window right now where we're really trying to aggressively attack this fire," said Daniel Berlant, a spokesman for the California Department of Forestry and Fire Protection.

House said there were no reports of people missing, but "we haven't really been able to get in there and see".-AP
