The fires started on Saturday and leaped from a hilltop to a densely populated area and may take up to 20 days to extinguish, according to Chile's forestry agency.
As many as 12,500 people have been affected by the devastating wildfires.
While fire victims include middle-class families, thousands more lived in primitive conditions, sharing structures built on tiny ledges of land carved into the hills, the Associated Press reported.
