Mount Etna By: Luke, Nick, and Steven

Did you know?? Mount Etna is Europe’s highest and most active volcano Towering above the city of Catania on the island of Sicily, it has been growing for about 500,000 years More than 25% of Sicily’s population lives on Etna’s slopes it is the main source of income for the island, both from agriculture (due to its rich volcanic soil) and tourism.

How big is mount Etna?? Mount Etna (or Aetna, also known locally as Mongibello) is an active volcano on the east coast of Sicily (Italian Sicilia), close to Messina and Catania. It is the largest volcano in Europe, standing about 3,320 m (10,900 ft) 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 (1190 km²). It is by far the largest of the four active volcanos 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 an almost constant state of eruption. Although it can occasionally be very destructive, it is not generally regarded as being particularly dangerous.

Who it effects?? Mount Etna effects the people living on the mountain by erupting and sending lava down the side tearing through peoples houses Mount Etna all so tears up the street and everything else around it

How it was created There are many different causes and most probably more than one occurred at the same time. Subduction where plates are pushing towards each other. The collision of two plates of the Earth's lithosphere, the African plate to the south and the European plate to the north. Back-arc rifting and continental rifting; Sea Floor spreading the hot spot beneath Etna. The volcano lies at the intersection of several major regional fault systems.

Names and Legends Etna was known in Roman times as Aetna, a name thought to have derived either from the Greek word aitho ("to burn") or the earlier Phoenician word attano. The Arabs called the mountain Gibel Utlamat ("the mountain of fire"); this name was later corrupted into Mons Gibel and subsequently Etna's current local name Mongibello.

Physical aspects Etna is an isolated peak which dominates the eastern side of Sicily, around 18 miles (29 km) from Catania. Its shape is that of a truncated cone with a ragged top, which is actually a complex of large volcanic cones hosting four summit craters. Around 260 smaller craters, formed by lateral eruptions, occupy the slopes. On the southeastern side of Etna lies an immense gully, the Valle del Bove, which is between ft ( m) deep and over 3 miles (5 km) wide. Many of Etna's subsidiary craters reside within this cleft, which is thought to have been created around 3,500 years ago by the collapse of an ancient caldera. The height of the mountain varies with its eruptions; until 1911, there was only one large cone and crater at the summit, but subsequent eruptions have created new craters and cones. The slopes of Etna form three distinct zones. The lower zone, extending up to about 4000 ft (1200 m) are densely populated and planted with vineyards, citrus fruits, and groves of olives, figs and almonds. The middle zone (up to about 6900 ft / 2100 m) is heavily wooded, mostly with pine and chestnut trees. At the top of the mountain is a volcanic wasteland, dominated by old lava flows, screes and volcanic ash. Few plants grow there and it is covered by snow for much of the year.
