Puyehue-Cordón Caulle [image] #NASA

Puyehue Cordón Caulle Volcanic Complex emitted a pale plume of gas and ash on August 18, 2011. Activity started on June 4, 2011. The ongoing eruption has been characterized by explosive emissions of ash and larger tephra, as well as the outpouring of lava typical of an effusive eruption. Evidence of both styles of eruption are visible in this natural-color satellite image, acquired by the Advanced Land Imager (ALI) aboard Earth Observing-1. A billowing ash plume indicates the explosive nature of the eruption. A fresh lava flow, darker than most of the surrounding, snow-covered landscape, illustrates the effusive aspect of the eruption. A light dusting of snow visible on the southern lobe of the flow indicates that the surface of the lava has cooled, although it was active as recently as July 31st. Signs of an older eruption are visible to the southwest (lower left) of the ...
