The Santiago Fire began shortly before 5:55pm on October 21, 2007 in the foothills north of Irvine and east of the city of Orange in Orange County. Fire officials have said that the source of the fire is arson; the fire was said to have been started in three different spots. The fire has burned over and is 30% contained. Strong winds have stopped people from fighting the fire and forced a dozen firefighters to seek emergency shelter under tents after the fire moved at them. Two homes, one mobile home, and one outbuilding have been destroyed. Several other buildings damaged, and four firefighters were a bit hurt from the fire. Damage estimates put the fire's cost at $5.5 million.
