A volcano in southern Chile has started spewing lava again, prompting officials to order a total evacuation of residents still living in the area.

More than 4,000 people have already been evacuated from the nearby town of Chaiten since the volcano began erupting on Friday.

Chilean President Michelle Bachelet oversaw the evacuation on Monday of Futaleufu, a small town on the border with Argentina and about 160 kilometers southeast of the volcano. Some areas in the town had as much as 30 centimeters of ash.
