Why does a magical circle of smoke appear on the crater?

A phenomenon that makes experts as well as the public curious is the appearance circle of smoke like rings appearing above craters in many places on Earth. These circles only last for a short time and then disappear.According to the eyewitnesses’ observations, the The smoke circle is round like a ring can stretch hundreds of meters. Researchers are currently unable to predict in advance when these circles will appear and how long they will disappear.Before this mysterious phenomenon, experts have spent a lot of time researching to find out the answer about the circle strange appearance above the volcano. Simona Scollo, a volcanologist at the National Institute of Geophysics and Volcanology in Italy, and colleagues carried out the study of those rings.According to the research team, the ring-like smoke rings that appear above the crater are created mainly from water vapor, not from smoke as many people think.Researcher Simona explains that the rings of smoke appearing above the crater are mostly made up of gas condensate, mainly water vapor, and ejected from the crater. Elements coming out of the crater usually slow down as they face the surface, causing the gas to rise on its own.However, it is not clear exactly what is happening inside a volcano to create the ring-like smoke rings. In addition, not every crater can create such strange rings.Dr. Scollo’s team scoured multiple sources and studied footage and images to find ring-like rings of smoke appearing above the crater captured on camera.As a result, the team discovered that the ring-like rings seen above some volcanoes are about 9-198m in diameter and last for about 10 minutes. The ring-like circles that appear above the crater are usually white, sometimes gray or brown from the ash.According to Simona’s team, strong winds can prevent the circles from forming or stay for a short time. On the other hand, the circles formed above the crater gradually drifted towards the sky and began to expand. Finally, when most of the evaporation was done, the rings disappeared.Meanwhile, volcanologists at the Sicilian observatory, Jurg Alean and Maro Fulle, speculate that the ring-like ring appearing above the crater is the result of very large outflows of gas. rapidly from the narrow fissures of the volcano.Invite readers to watch the video: Volcano erupts violently in Iceland.
