1. Volcanoes

2. WTH is a Volcano
A volcano is a vent in the earth’s crust through which Lava, Steam, ashes and etc. are expelled.

3. How are they Formed ?
When tectonic plates collide and go through the process of subduction, it sets the foundation for a volcano. The overlapping of the tectonic plates causes the magma to break through the crust, which is the cause of a volcanoes' birth
Between the molten iron core and the thin crust at the earth’s surface, a solid body of rock lies within. When temperature and pressure rises, the rock melts and moves through the surface and crust, and releases gases and magma. This is a description of a volcanic eruption.

4. Mount Vesuvius
Mt. Vesuvius is located on the west coast of Italy. It overlooks the city of Naples and sits on the crater of the ancient Somma volcano. Mount Vesuvius formed over 25,000 years ago. The last eruption of Mt. Vesuvius was on March 13, The eruption lasted intermittently till the 18th. Mt. Vesuvius has an altitude of 1,821 meters. It covers about 480 square km of land and its lava chamber has a depth of 5-6 km. The diameter of the mouth is 6 kilometers.

5. Mount Vesuvius Effects
The eruption caught the military and destroyed the air force planes stationed in the airport of Terzigho, east of the mountain. An entire wing of 88 B-25 was damaged by the eruption. There were a few casualties caused by the explosion of a water tank invested by a lava flow. The major economic losses resulted by the destruction of the villages S.Sebastiano and Massa, by the Lava flow
