I’ve exceeded my Twitter views 😤, so I had to look up on YouTube. Wow!!!!! https://youtu.be/Q2cUGICVE...

Mount Etna is one of a handful of volcanoes around the world that produces the rings, and does so prolifically, but the latest emissions are exceptional, scientists say.

The smoke circles, known as volcanic vortex rings, are actually made of condensed gases and water vapor. They form when gases rise up from deep below the earth and escape inside the crater of a volcano.

“No volcano on earth produces so many rings of steam as Etna. We have known this for quite some time. But now it is beating all previous records,” said Boris Behncke, a volcanologist at the National Institute of Geophysics and Volcanology of Catania. He has been studying the volcano and living close to it for the past 25 years. He said that on late Tuesday a small vent opened on the north-east edge of the south-east crater, which had emitted puffs of incandescent gas. The following morning, it became clear that these puffs were creating “an impressive quantity” of vortex rings, he said.
