Destroying the ancient cities of Pompeii and Herculaneum, the infamous volcano Mount Vesuvius still poses as a threat to Italian cities nearby. When this unpredictable volcano erupted in 79 CE, thousands were killed and many were left in the ash that captured the area. We know so much about this eruption because of an eyewitness named Pliny the Younger. He wrote letters after the eruption that told about the type of eruption and the destruction it caused, all from his view of the two day catastrophe many miles away (Ball, 2014).
Currently, this large volcano stands at 4,203 feet (Wikipedia, 2014), but it has not always been that way. The composite, otherwise known as stratovolcano, was constantly added to by the running over of lava from the cone, while rock and other pyroclastic debris were ejected as well. Initially formed by the subduction of the African under the Eurasian plate, the water from the oceanic African plate caused the melting point of the mantle to lower, creating the magma that led to the volcano (Wikipedia, 2014). Then, seventeen thousand years ago a caldera was formed from an explosion and then within it grew the cone of Mount Vesuvius (Wikipedia, 2014).
In 62 CE, there was an earthquake that is thought to be the start to the volcanic activity that caused the explosion of 79. It caused much damage around the Bay of Naples, and especially to Pompeii (Wikipedia, 2014). Researchers believe that the tectonic activity caused new activity in the volcano, with tremors becoming more frequent within days of the eruption (Wikipedia, 2014). The morning the most destructive eruption occurred, Pliny described it as “an umbrella pine, for it rose to a great height on a sort of trunk and then split off into branches…. Sometim...

...han ten kilometers below the surface (Wikipedia, 2014). It is monitored by the multiple stations of the Osservatorio Vesuvio, who use many techniques to track the level of the magma. They measure ground movement and analyze the gases emitted from the volcano in order to do so (Wikipedia, 2014). Because Mount Vesuvius is not a danger in the near future, it was declared a national park. There is a network of paths around the mountain that leads to the summit, open to visitors (Wikipedia, 2014).
