Watch: ”Anedousa” Fog Fills Santorini’s Caldera

Few tourists have ever witnessed the event, said to be caused by temperature differences between Santorini's famous volcano and the island itself.

A heavy fog, locally known as “anedousa”, rose rapidly from the sea and filled the famous caldera with what looked like smoke – as if the island’s active volcano had suddenly erupted, or as if a cloud had descended and gently blanketed the villages of Oia, Fira and Imerovigli.

In videos on Instagram, the villages resemble those on the mountains of the Greek mainland, hovering above the clouds.
