Volcanoes form as a result of tectonic plate movement and pressure changes below the earth's surface. When magma breaks through the crust, a volcanic eruption occurs, expelling lava, steam, ash and other materials. Mount Vesuvius is a famous volcano near Naples, Italy that formed over 25,000 years ago. Its last eruption in 1944 caused widespread damage, destroying villages and aircraft at a nearby airfield. Volcanic eruptions are powerful natural events that can have significant effects on the surrounding area.

By: Yendor Poe

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, 1944. 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
