"Mount Etna's Rare and Spectacular Volcanic Vortex Rings Captured in Photos and Videos"
TL;DR
Mount Etna, Europe’s largest active volcano, recently produced near-perfect rings of gas and vapor, known as "volcanic vortex rings," through the rapid release of gas and vapors from a newly formed crater. These rings, composed mostly of water vapor, resemble smoke rings and are not particularly rare phenomena for the prolific volcano.
