April 7th - "Nature's handiwork" is often used to marvel at the wonders of nature, and behind these miraculous natural phenomena lies scientific principles.
According to reports from CCTV Finance, recently, the Mount Etna volcano in Italy erupted with "smoke rings," a spectacle that attracted a large number of tourists to gather and capture the moment.
How are these "smoke rings" formed? This question has sparked heated discussions among many netizens.
From the photo, it appears that a significant amount of white gas rings are emanating from a crater atop Mount Etna, resembling individual "smoke rings".
It's known as a phenomenon called "volcanic rings," where during volcanic eruptions, hot gases, lava fragments, and ash are rapidly expelled into the atmosphere from the volcano's vent. These substances mix with the surrounding air and water vapor, forming smoke rings through the volcanic eruption's airflow and convective motions, thus creating this phenomenon known as volcanic "smoke rings."
Italian volcanologists report that Mount Etna has emitted "several hundred or even thousands of vortex rings" since April 3. The amount of vortex rings emitted by Mount Etna surpasses any other volcano, creating a spectacular scene that locals have dubbed "Lady of the Rings."
Mount Etna, standing at over 3,300 meters above sea level, is the highest and most active volcano in Europe.
