Beginning on September 6, 2010, Chile’s ice-covered Planchón-Peteroa Volcano has erupted a series of small ash and gas clouds. The chilean National Service of Geology and Mining (Sernageomin) reported that the eruptions were probably phreatomagmatic: caused by the interaction of water with magma inside the volcano.

This natural-color satellite image was acquired on September 18, 2010, by the Advanced Land Imager (ALI) aboard Earth Observing-1 (EO-1). A dark volcanic plume trails at least 22 kilometers (14 miles) southeast & into Argentina from the Peteroa summit (the currently active crater). Fallen ash colors the snow underneath the plume brown.
