Vesúvíus er samsett eldfjall sem samanstendur af gjóskuflæði, hraunflæði og rusli frá laharum sem safnaðist saman til að mynda eldkeiluna.

hvernig gerðist þetta

As the African tectonic plate is pushed under the Eurasian plate, a portion of the lower plate has detached from the upper part, creating what is known as a “slab window.” This promotes melting of a different type of rock underneath Vesuvius than what is around it, and this winds up favoring violent eruptions. This rock is known as andesite, a volcanic rock that has around 50-60% silica content. This relatively high amount of silica creates “sticky” magma that traps gases and water to create explosive eruptions, making Vesuvius especially dangerous and unpredictable.'

The eruption of Mt. Vesuvius in 79 AD is one of the most well-known volcanic eruptions in history. The violent eruption came with little warning, ejecting monumental amounts of ash, mud and rocks into the air and onto the Roman cities of Pompeii and Herculaneum.
