Gas and ash stream from multiple craters on Sicily’s Mount Etna in this natural-color satellite image. Dark lava, ash, cinders, and scoria (dense volcanic rock filled with gas bubbles) coat the southeastern slopes. The image was collected by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite on March 23, 2013.
