MT. Vesuvius
Mt. Vesuvius last major eruption was in 79 A.D. when it destroyed the cities of Herculaneum and Pompeii, however there have been many sense! When Vesuvius erupted in covered everything 20 feet with in the debris. During the eruption around 2000 people died. The eruption was called a plinian explosion. Which means that when extremely gas rich magma explodes deep inside a volcano and a tremendous blast shoots straight up at twice the speed of sound (the vent playing the role of a gun barrel) creating a column of ash as much as 20 miles high. Mt. Vesuvius, last erupted in 1944.
Mt. Vesuvius
is located in Southern Italy near Naples. Its base is 48 Kilometers (30
miles), with a height of 1277 Kilometers (4190 feet). Vesuvius is 17,000
years old, and it has had around 50 eruptions, the most famous one in 79
AD. The main danger is that there are around 2 million people that live
there. Pompeii and Herculaneun were not the only things that were changed/destroyed.
It changed the coast of Sarnus, and raised the sea beach, placing the river
and sea at a considerable distance of were it originally began.
