The NASA Earth Observatory has taken some stunning high resolution images of an eruption from the Puyehue-Cordón Caulle Complex in Chile that consists of four different volcanoes. Ash plumes have reached two to four kilometers in altitude and have drifted 90 to 320 kilometers downwind affecting surrounding areas including forests, farmlands and resorts.
This is another image of the region from 23 December 2011. The volcano erupted violently last June (causing the evacuation of thousands of people), but ash and steam continued to escape from a fissure that opened several months earlier.
