| Mount Etna is Europe's tallest active volcano and is located in Sicily, Italy. Like many other dangerous volcanoes such as Mount St Helens and Mount Vesuvius, Etna is a composite volcano. It has been created by the Earth's active tectonic plate system – the African plate is moving below the Eurasian plate. As the Eurasian plate moves down into the Earth, it melts. Rising magma erupts at the surface as lava and ash and builds Etna in the process.
Etna has erupted many times during recorded history and is still very active.

Etna and Vesuvio are close to settlements, while the most violent of the three volcanoes in Southern Italy, the Stromboli

is OFFshore and therefore not as much as a problem as the Etna
