Etna, one of Europe’s most active volcanoes, has been spewing circular, mostly white smoke rings into the skies over Sicily. The rings, known as volcanic vortex rings, appeared earlier this month after a small vent opened on the northwest border of the Southeast crater. In this case, the vent is perfectly circular, making for particularly perfect rings. “It is bellissimo,” said Simona Scollo, another volcanologist at the INGV Etna Observatory in Catania, using the Italian word for beautiful. Ms. Scollo copublished a study on the dynamics of volcanic vortex rings last year in the journal Scientific Reports.

CNN —Flights from Catania airport in Sicily were grounded on Sunday after volcanic ash from an eruption of Mount Etna covered the runways. Volcanic ash in Nicolosi, near Catania Orietta Scardino/EPA-EFE/ShutterstockPictures and video footage show black volcanic ash covering planes at the airport, and blanketing roads in the area. In 2010, a volcanic eruption in Iceland sent a huge plume of ash moving across the Atlantic, causing massive disruption to air traffic across Western Europe. In the aftermath of the crisis, international aviation regulators introduced new risk management guidance on flight safety and volcanic ash. Mount Etna is Europe’s most active volcano, and also the highest, at about 3,350 meters (almost 11,000 feet) tall.
