| Mount Vesuvius, located in southern Italy, is the only volcano in mainland Europe to have erupted in the last 100 years. It is most famous, however, for its eruption in 79 AD that completely buried the towns of Pompeii and Herculaneum in layers of burning ash. According to the only known surviving witness, Pliny the Younger, the cloud of ash that descended upon the cities may have been 20 miles high. Despite the fact that Mount Vesuvius is not currently erupting, it is considered one of the most dangerous volcanoes in the world because 3,000,000 people live near it. |
