A plume of light-coloured ash stretches along the edge of the Andes in this natural-colour satellite image acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard Terra on the morning of June 6, 2011, as the eruption at the Puyehue-Cordon Caulle volcano chain continues. The volcano dormant for decades erupted in south-central Chile on Saturday belching an ash cloud more than 6 miles high that blew over the Andes and carpeted a popular ski resort in neighboring Argentina. The eruption took place about 575 miles south of the capital Santiago.
