Mount Vesuvius (Italian: Monte Vesuvio, Latin: Mons Vesuvius) is a stratovolcano on the Gulf of Naples, Italy. It is about 9 kilometres (5.6 mi) east of Naples. It is the only volcano on the mainland of Europe that erupted in the last 100 years. The last major eruption was in 1944. Two other important active volcanos in Italy, Etna and Stromboli, are on islands.
