Colonna di fumo e lampi vulcanici sul vulcano Puyehue

A column of smoke and volcanic lightning are seen over the Puyehue volcano, over 500 miles south of Santiago, Chile, Sunday June 5, 2011. Authorities have evacuated about 600 people in the nearby area. The volcano was calm on Sunday, one day 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.
