Authorities have evacuated about 3,500 people in the nearby area from the erupting Puyehue-Cordon Caulle volcano in Rininahue near Lago Ranco, over 500 miles south of Santiago, Chile, Monday June 6, 2011. The volcano was calm on Monday, two days after raining down ash and forcing thousands to flee, although the cloud of soot it had belched out still darkened skies as far away as Argentina.
