>> Mount Etna
A real miracle of nature is taking place in Italy. Mount Etna, Europe's most active volcano in Sicily, emits rare smoke rings that rise high into the sky.
This phenomenon is quite rare, as smoke rings only form with a certain shape of the crater.
The most active volcano in Europe has been showing an unusual sight since last week – the eruption of rings of smoke and water vapor rising high into the sky. The phenomenon is known as “volcanic vortex rings”, caused by the explosion of gas bubbles above the magma chamber.
The news of Etna volcano activity is causing concern among local residents and scientists who follow this natural phenomenon. Volcanic activity always attracts public attention because of its potential danger and impact on the environment.
Of course, when occurring in nature, these phenomena have their own majesty and beauty, but it is also important to understand their potential threat to life and health of people, researchers emphasize.
The term volcanic vortex rings was introduced by the English physicist William Thomson (1824-1907). Such rings have also been spotted on another famous Italian volcano, Stromboli, on the island of the same name in the Mediterranean Sea. According to experts, they are completely harmless and have no signs of future eruption.
