A brand new vent on Italy’s Mt. Etna, a UNESCO World Heritage Web site and one of many world’s most lively volcanoes, has been puffing what appear to be white and pink smoke rings into the sky above Sicily since early April.
The spherical, cloud-like rings — generally known as volcanic vortex rings — are in actual fact a mixture of water vapor, sulfur dioxide and carbon dioxide, volcanologist Boris Behnke lately advised The Washington Put up.
Their look above Etna was first reported in 1792, however this month’s spate of rings “has damaged all earlier data” when it comes to frequency, stated Behnke, a scientist on the Nationwide Institute of Geophysics and Volcanology of Catania in Italy, who cited a 2023 research printed within the journal Scientific Studies that exposed new info on how and why the rings happen.
Mainly, a vent opens within the volcano, as Etna lately skilled on its southeast crater. From there, the stress contained in the crater begins to construct, inflicting the magma to power condensed gases out of the vent. The water-vapor combo, together with the spherical form of the vent, seemingly creates the spherical clouds and sends them wafting up above the volcano.
“It’s bellissimo,” stated Simona Scollo, who co-published the 2023 research on the rings, in a latest interview with The New York Occasions about Etna’s gorgeous white and pink rings.
“Bellissimo” means “stunning” in Italian.

The southeast crater of Mt. Etna, an iconic stratovolcano in Catania, Italy, is seen at sundown because it emits gasoline and steam rings known as volcanic vortex rings on April 6, 2024.
When Mt. Etna turned a UNESCO World Heritage website in 2013, it was deemed “the best Mediterranean island mountain and probably the most lively stratovolcano on the earth.”

On this picture, volcanic vortex rings are generated by the southeast crater of Mt. Etna, a volcano in Catania, Italy, on April 6, 2024.
The formation of steam rings is a really uncommon phenomenon that solely happens underneath particular circumstances, when there’s a fixed venting of vapor and gasoline from Etna’s volcano. The gaseous mass rises with pace within the central a part of the conduit, favoring the formation of the rings by the winding of the gasoline round itself in a vortex movement.

“The eruptive historical past of the volcano could be traced again 500,000 years and no less than 2,700 years of this exercise has been documented,” in accordance with UNESCO’s World Heritage itemizing for Etna.

A photograph taken from Riposto, Italy, reveals an eruption at Mt. Etna in Catania, Italy, on July 7, 2021. The Southeast crater erupted a bit of greater than 48 hours after the final volcanic occasion there, with the best jets of the lava fountain reaching 1,000 meters.
The eruptive column was carried by the wind to the south, and the heavy rain of ash fell on town of Catania. It was the forty sixth eruptive episode in 2021, marking the most important sequence of eruptions in a brief time frame in 20 years.
