Mount Etna, is an active stratovolcano on the east coast of Sicily, Italy, in the Metropolitan City of Catania, between the cities of Messina and Catania.
It is located above the convergent plate margin between the African Plate and the Eurasian Plate
Mount Etna is the highest Mediterranean island mountain and the most active stratovolcano in the world.
The volcano also supports important terrestrial ecosystems including endemic flora and fauna and its activity makes it a natural laboratory for the study of ecological and biological processes.
The diverse and accessible range of volcanic features such as summit craters, cinder cones, lava flows and the Valle de Bove depression have made the site a prime destination for research and education.
In June 2013, Mount Etna was added to the list of UNESCO World Heritage Sites.
Volcanic vortex rings- the phenomenon was more common at Mount Etna than at other volcanoes, and the shape was on account of the geometry of the conduit.
It's a very active volcano. It has a very defined geometry internally
It's a very open-system volcano.
It tends to form very large bubbles.
The shallower they get, the bigger they get, and so it forms this circular bubble towards the surface then have only the edges of the vents that are allowing these rings to form.
