The smoke circles rising from the top of the mountain make everyone curious, what is the truth?

Many people were very surprised to see and record images of circular smoke circles flying from the top of a mountain high into the sky. This is a very rare phenomenon, as explained by scientists.

A strange scene took place last weekend: Plumes of smoke rose from the top of the Etna volcano (Sicily, Italy) and formed spreading circles, flying high. People near this area, including many tourists, were surprised by this magical image and were curious about what phenomenon this was and whether it was dangerous or not.

According to Dr. Boris Behncke at the National Institute of Geophysics and Volcanology in Catania (Italy), these circles look like smoke but are not difficult . They are a combination of various condensed gases - mainly water vapor - that escape from magma (molten rock) and rise rapidly from the crater. When these gases escape from the volcano in short bursts, they can form circular shapes.

The phenomenon of many circles of gas rising from Mount Etna is called 'volcanic vortex ', and is an extremely rare phenomenon, according to AP. Although not unprecedented, 'volcanic spirals' only occur when the crater is circular and in a still atmosphere. If there is strong wind, air circles cannot form.

Dr. Behncke told Italian media that Mount Etna produces these interesting circles more than any other volcano on Earth.

And although the image of smoke rings rising from the crater may be quite mysterious to many people, volcanologists say this phenomenon is not harmful at all.

Mount Etna erupts quite frequently and its activity has been recorded for more than 3,500 years, according to AccuWeather.
