Vortex Rings

  • 13 Apr 2024

Mount Etna, Europe's largest volcano, showcases rare volcanic vortex rings, a phenomenon akin to smoke rings.

  • These rings are formed by the rapid release of gas, primarily water vapor, through circular vents in the crater.
  • Etna's continuous activity includes both summit and flank eruptions, with documented events dating back 500,000 years.
  • Volcanic vortex rings have been observed at various volcanoes worldwide, with Etna being a notable hotspot.
