Views Of Mount Etna With SAGF Mountain Rescue Team

CATANIA, ITALY - AUGUST 09: Smoke rings, composed of a mixture of smoke, steam and other gases expelled at high speed, above the Etna on August 09, 2023 in Catania, Italy. The smoke rings, a rare and fascinating sight in recent days, are emitted from a single vent located in one of its most active craters.
