GK: SOUTHEAST FLANK OF MOUNT ETNA IN SICILY IS SLIDING TOWARDS THE SEA
- The southeast flank of Mount Etna in Sicily is sliding towards the sea at a rate of several centimetres a year.
- It’s likely caused by gravity pulling on Etna’s lower underwater slopes, far from the summit.
- The kind of stress that this movement creates inside volcanoes can cause devastating landslides. This means Etna is more susceptible to catastrophic collapse than had previously been realised.
About Mt. Etna:
- Mount Etna is the largest active volcano in Europe and one of the world’s most frequently erupting volcanoes. It is also the volcano with the longest record of continuous eruption.
- Located near the east coast of the island of Sicily in Italy, Mount Etna is 10,900 feet (3,329 meters) tall with a base circumference of about 93 miles (150 kilometers).
- The mountain’s largest feature is the Valle del Bove (Valley of the Ox), a large horseshoe-shaped caldera on the eastern slope.
- Etna sits on the active fault between the African plate and the Ionian microplate, which are both being subducted together beneath the Eurasian plate.
- In June 2013, it was added to the list of UNESCO World Heritage Sites.
- Due to its history of recent activity and nearby population, Mount Etna has been designated a Decade Volcano by the United Nations.
