Volcanic ash rose into the sky above Mount Etna as Europe’s most active volcano shifted its behaviour, prompting scientists to issue a red aviation alert.⁣ ⁣ The Volcano Observatory Notice for Aviation (VONA) warns of a potential risk to aircraft due to ash in the airspace. Despite the alert, authorities say flights at Catania Fontanarossa Airport are operating normally, with no disruption expected unless ashfall intensifies.⁣ ⁣ Mount Etna, which towers more than 3,300 metres above eastern Sicily, is under constant monitoring as activity continues.⁣ ⁣ #MountEtna #Volcano #Italy #Sicily
