Mount Etna is an active stratovolcano on the east coast of Sicily, Italy, between the cities of Messina and Catania. At a height of 10,912 feet (3,326 m), it is by far the largest active volcano in Italy — roughly two and a half times taller than Mount Vesuvius. Etna is one of the world’s most active volcanoes and has erupted at least 49 times since January 1955.
