Natural hazards: regional risks include landslides, mudflows, avalanches, earthquakes, volcanic eruptions, flooding; land subsidence in Venice
volcanism: significant volcanic activity; Etna (3,330 m), which is in eruption as of 2010, is Europe's most active volcano; flank eruptions pose a threat to nearby Sicilian villages; Etna, along with the famous Vesuvius, which remains a threat to the millions of nearby residents in the Bay of Naples area, have both been deemed Decade Volcanoes by the International Association of Volcanology and Chemistry of the Earth's Interior, worthy of study due to their explosive history and close proximity to human populations; Stromboli, on its namesake island, has also been continuously active with moderate volcanic activity; other historically active volcanoes include Campi Flegrei, Ischia, Larderello, Pantelleria, Vulcano, and Vulsini
Definition: This entry lists potential natural disasters. For countries where volcanic activity is common, a volcanism subfield highlights historically active volcanoes.
