Artist's impression of volcanic vents on Mount Etna, Sicily. Mount Etna (3323 metres) is a large volcano, transitional in nature between shield and stratovolcano types. Four main summit vents are known, but Etna has also shown extensive flank eruptions. Lava flows have been observed more than 150 times since 1500 BC, most recently in 1992. The last fatal eruption was in 1979, when nine people died, but much damage is done to property and land in most eruptions.
