Introduction The eruption of Mount Vesuvius in 79 AD was a pyroclastic event discussed in greater detail over the course of this essay. Mount Vesuvius is located on the southern coast of Italy, 1,281 metres above the Bay of Naples on the plain of Campania between the Apennine Mountains and the Tyrrhenian Sea. Mount Vesuvius is part of the Romana volcanic belt which covers about 450km from Mount Amatia, 130km from north-west Rome and 110km from East Naples. The Romana volcanic belt is made up of two parallel volcanic scars. Mount Vesuvius is on the Western arc. This zone is highly fractured which allows magma to rise up into the magma chamber beneath Mount Vesuvius. This chamber is thought to be approximately 5km below the volcano and almost 2km high with a diameter of around 1km. The volcano is situated where two faults in the Earth’s crust converge. (De Boer and Sanders, 2002) Development of Mount Vesuvius Mount Vesuvius developed inside the caldera of an older volcano. This volcano was known as Monte Somma. Monte Somma became active around 400,000 years ago. Only the northern side of Monte Somma is left, creating a wall-like ridge around the northern edge of Mount Vesuvius. This feature can be observed today at the site of Mount Vesuvius. The development of Vesuvius produced a volcanic complex consisting of the two volcanoes.
