Mount Etna

Why in news? Europe’s most active volcano Mount Etna erupted recently.

About:

  • Mount Etna is the highest Mediterranean island mountain and the most active stratovolcano or Composite volcano in the world.
  • It is located on the island of Sicily, Italy.
  • It lies above the convergent plate margin between the African Plate and the Eurasian Plate.
  • It is the tallest active volcano in Europe and a UNESCO World Heritage Site.
  • Etna has also produced pyroclastic flows, ashfalls, and mudflows, but the lava flows are the most immediately hazardous type of activity, especially to the city of Catania.

Composite volcano

  • Cone-shaped volcanoes built from many layers of lava, pumice, ash, and tephra.
  • Due to multiple layers of viscous material, rather than fluid lava, composite volcanoes tend to form tall peaks rather than rounded cones.
  • So far, Mars is the only place in the solar system besides Earth known to have stratovolcanoes.
