3. How big is mount Etna? Mount Etna is an active volcano on the east coast of Sicily, close to Messina and Catania. It is the largest volcano in Europe, standing about 3,320 m high with a basal circumference of 140 km, making it the highest mountain in Italy south of the Alps. Etna covers an area of 460 square miles. It is by far the largest of the four active volcanoes in Italy, being nearly three times the height of the next largest, Mount Vesuvius. It is one of the most active volcanoes in the world and is in almost constant state of eruption. Although it can rarely be destructive, it is not generally regarded as being particularly dangerous.

4. What are its effects on people? Mount Etna's eruptions sending lava down the sides tear through people's houses and everything else around

5. Its origins There are many different causes and most probably more than one occurred at the same time. One of this is the collision of two plates of the Earth's lithosphere, the African plate to the south and the European plate to the north. The volcano lies at the intersection of several major regional fault systems.
