A new crater on Mount Etna's summit has produced rare volcanic vortex rings, a phenomenon caused by rapid gas release and vent shape. This event has broken previous records, according to volcanologist Boris Behncke.
The " volcanic vortex rings ", a rare phenomenon generated by the combination of rapid gas release and the vent shape , spewed out of a new crater that opened on Tuesday on Etna's summit.
Boris Behncke, volcanologist at the National Institute of Geophysics and Volcanology in Catania Boris, explained in a Facebook post that "no volcano on Earth produces as many vapour rings as Etna".Etna is breaking all previous records, Behncke wrote. "In the late afternoon of 2 April 2024, a small mouth opened on the north-eastern rim of the South-East Crater, producing puffs of glowing gas," he added.Volcanic vortex rings are formed by a combination of fast gas release at the top of the magma conduit and regularity in the shape of the emitting vent. Volcanic vortex rings emerge from a new pit crater on Etna.
"By the next morning it was evident that these puffs were producing an impressive amount of steam rings, and this activity has been going on ever since, having already emitted hundreds if not thousands of these pretty rings." There were no reports of particular disruptions in the surrounding villages or at Catania airport, which often closes in the case of major eruptions.In 2021, Etna emitted so much volcanic material over six months that it grew in height by almost 30 metres.The summit area consists of five main craters, and most eruptions take place from one of these craters.
