Mount Etna, Not Quite Restful

Mount Etna, Not Quite Restful

Mount Etna belches out volcanic gases in this natural-color satellite image. Relatively quiet since its last paroxysm on April 24, 2012, the volcano still emits a lively, blue-tinted plume. These gases are emitted from the Northeast Crater, while most recent lava flows (25 since January 2011) have erupted from the new Southeast Crater, lower down the mountainside. This image was collected by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite on June 26, 2012.
