Volcanoes
Mount Vesuvius, on the west coast of Italy, is the only active volcano on mainland Europe. It is best known because of the eruption in A.D. 79 that destroyed the city of Pompeii. Mount Vesuvius is considered to be one of the most dangerous volcanoes in the world due to the large population of the city of Naples and the surrounding towns on the slopes nearby.
The eruption of Krakatoa in August 1883 was one of the most deadly volcanic eruptions of modern history. It is estimated that more than 36,000 people died. Many died as a result of thermal injury from the blasts and many more were victims of the tsunamis that followed the collapse of the volcano into the caldera below sea level.
