Mount Etna, the highest volcano in Europe, is famous for its eruptive activity and its fascinating volcanic phenomena. Among these, one of the most spectacular is the formation of gas rings.
What are gas rings?
These are circular formations, composed of volcanic gases, that form inside the volcano’s crater. These gases, mainly carbon dioxide, sulfur dioxide, and water vapor, rise to the surface through the volcanic conduit and, due to their different rising speeds, expand creating a vortex that takes the shape of a ring.
How do they form?
The formation of gas rings is a complex process that begins with the degassing of magma. The magma, rising to the surface, releases the gases that accumulate inside the volcanic conduit. When the gas pressure becomes too high, an explosion occurs that releases the gas bubbles to the surface.
Where can they be seen?
Gas rings are visible in several craters of Etna, but the best place to observe them is the Bocca Nuova, a crater formed in 1968. This crater is characterized by persistent Strombolian activity, which favors the formation of frequent gas rings.
A fascinating and safe phenomenon
Etna’s gas rings are a fascinating and safe phenomenon to observe. However, it is important to keep a safe distance from the crater and follow the instructions of the volcanological guides.
An unforgettable experience
If you have the opportunity to visit Etna, don’t miss the chance to observe the gas rings. It is a unique and unforgettable experience that will allow you to admire the power and beauty of nature.
