Mount Etna

Mount Etna is an active volcano on the east coast of Sicily, close to Messina and Catania. It is the largest active volcano in Europe, currently standing about 3,350 m (10,991 ft) high, though it should be noted that this varies with summit eruptions; the mountain is 21.6 m (71 ft) lower now than it was in 1865. It is the highest mountain in Italy south of the Alps. Etna covers an area of 1190 km² (460 square miles) with a basal circumference of 140 km. This makes it by far the largest of the three active volcanoes in Italy, being nearly three times the height of the next largest, Mount Vesuvius.

It is one of the most active volcanoes in the world and is in an almost constant state of eruption.
