Italy - August 13th, 2011

Mount Etna, a volcano on the Italian island of Sicily, has being having short, violent bursts of activity known as paroxysms throughout the year. Each paroxysm has included volcanic tremors, emissions of ash and lava flows, all concentrated around the New Southeast Crater, which is located just below the volcano’s summit.

Etna’s tenth paroxysm of 2011 occurred on August 12th, as reported by NASA. This image shows the volcano the day after the event, still releasing a white plume of gas and ash to the southeast, towards the nearby city of Catania. Like the other events, the activity began at the New Southeast Crater. This time, fountaining of lava produced the ash plume, which was estimated to have reached an altitude of 14,000 feet (4,300 meters); 2,000 feet (600 meters) above the 10,925-foot (3,330-meter) summit.
