Many elements of the Italian territory are of volcanic origin. Most of the small islands and archipelagos in the south, like Capraia, Ponza, Ischia, Eolie, Ustica and Pantelleria are volcanic islands. There are also active volcanoes: Etna, in Sicily, the largest active volcano in Europe; Vulcano, Stromboli, and Vesuvius, near Naples, the only active volcano on mainland Europe.
