Mount Vesuvius, on the west coast of Italy, is the only active volcano on
mainland Europe. It is best known because of the eruption in A.D. 79 that
destroyed the city of Pompeii. Mount Vesuvius is considered to be one of the
most dangerous volcanoes in the world due to the large population of the city
of Naples and the surrounding towns on the slopes nearby.
The volcano is classed as a complex stratovolcano because its eruptions
typically involve explosive eruptions as well as pyroclastic flows. Vesuvius
and other Italian volcanoes, such as Campi Flegrei and Stromboli, are part of
the Campanian volcanic arc. The Campanian arc sits on a tectonic boundary where
the African plate is being subducted beneath the Eurasian plate.
Vesuvius has erupted many times since and is the only volcano on the
European mainland to have erupted within the last hundred years. Today, it is
regarded as one of the most dangerous volcanoes in the world because of the
population of 3,000,000 people living nearby and its tendency towards explosive
(Plinian) eruptions. It is the most densely populated volcanic region in the
world.
The area around Vesuvius was officially declared a national park on June 5,
1995. The summit of Vesuvius is open to visitors and there is a small network
of paths around the mountain that are maintained by the park authorities on
weekends.
There is access by road to within 200 metres of the summit (measured
vertically), but thereafter access is on foot only. There is a spiral walkway
around the mountain from the road to the crater.
