  • VVR, also known as volcanic smoke rings, are generated when gas, predominantly water vapor, is released rapidly through a circular vent in the volcanic crater. 
  • Mt Etna is the world’s most active volcano, located on the east coast of Sicily (Italy).
    • Also, it is the largest volcano of Europe. 
    • It lies in the highly active tectonic zone of Mediterranean Sea region which is part of the Mid-continental Volcanic Belt. 
      • The other important belt includes Circum pacific (ring of fire) and Mid-Atlantic belt
         
  • Why Mediterranean Sea region has highly active tectonic zone? 
    • Located on the convergent boundary between the Eurasian and African continental plates, and other minor plates. 
    • Convergence of plates creates subduction zone in western part of sea leading to formation of volcanoes. 
      • A subduction zone is a collision between two of Earth's tectonic plates, where one plate sinks into the mantle underneath the other plate.
    • Chains of submarine volcanoes have been created in the sea. 
    • The important volcanoes in the region are Mt Vesuvius, Stromboli, etc.
