Located on the east coast of the Gulf of Naples in southern Italy, Mount Vesuvius erupted violently in 79 AD, destroying the ancient cities of Pompeii and Herculaneum nearby at the time, and now the volcano and ancient city have become famous tourist attractions in Italy. Vesuvius erupted several times after that eruption, the last of which was in 1944, forming a huge volcanic cone, with a crater 600 meters in diameter and about 300 meters deep, in a semi-dormant state. Touring the volcano from the bottom of the mountain to the crater requires half an hour to climb. There is a guardrail plank road around the crater, and visitors can watch it. The plank road only builds a distance of half the crater. The crater is black with charred black and white smoke is coming out at the bottom.
