Etna, Sicily, Italy – Mount Etna is an active stratovolcano on the east coast of Sicily, Italy, in the Province of Catania. It lies above the convergent plate margin between the African Plate and the Eurasian Plate. It is the tallest active volcano in Europe, currently 3,329 m high, though this varies with summit eruptions. It is the highest mountain in Italy south of the Alps. Mount Etna is one of the most active volcanoes in the world and is in an almost constant state of activity. The fertile volcanic soils support extensive agriculture, with vineyards and orchards spread across the lower slopes of the mountain and the broad Plain of Catania to the south.

The fertile volcanic soils support extensive agriculture, with vineyards and orchards spread across the lower slopes of the mountain and the broad Plain of Catania to the south. Dangers of Volcanoes: Lava Flows: Most traditionally associated with volcanoes, but probably one of the least dangerous hazards to humans. Lava flows only travel up to a couple of km/hr so it is possible to move out of their way. However, they can bury and incinerate any land or property that they travel over. Pyroclastic Flows: These are giant clouds of ash and gas. They are extremely dangerous because they can travel up to 500 km/hr, reach distances of 30km and can be over 700 degrees centigrade in temperature. They will burn, knock over or bury anything in their path. Lahars: These are a secondary hazard and normally occur on snow covered volcanoes. Hots ash and gas melt the snow and then mix. They then travel down the volcano as a fast moving mudflow which can drown or bury anything in their path. Ash Clouds: Not as fast moving as a pyroclastic flow, but ash clouds can still be very disruptive. The weight of falling ash can collapse buildings and destroy crops. They can reduce sunlight by blocking out the sun and even cause problems for air travel like the recent Iceland volcano. Lava or Volcanic Bombs (tephra): When volcanoes erupt they often throw out semi molten pieces of rocks. As long as humans are a safe distance they don't really pose any problems. However, because of their heat they can start fires. Poisonous Gases: When volcanoes erupt they can release poisonous gases like carbon monoxide and sulphur dioxide. These can kill humans or animals if they are too close, but they can also contribute to the greenhouse effect.
