Cousteau looked for the lost city of Atlantis here. On Santorini
Crescent-shaped Santorini (or Thíra), the precious gem of the Aegean, is actually a group of islands consisting of Thíra, Thirassiá, Asproníssi, Palea and Nea Kaméni in the southernmost part of Cyclades.
Did you know that the whole complex of Santorini islands is still an active volcano (the same as Méthana, Mílos and Nísiros) and probably the only volcano in the world whose crater is in the sea? The islands that form Santorini came into existence as a result of intensive volcanic activity; twelve huge eruptions occurred, one every 20,000 years approximately, and each violent eruption caused the collapse of the volcano’s central part creating a large crater (caldera). The volcano, however, managed to recreate itself over and over again.
The last big eruption occurred 3,600 years ago (during the Minoan Age), when igneous material (mainly ash, pumice and lava stones) covered the three islands (Thíra, Thirassiá and Asproníssi). The eruption destroyed the thriving local prehistoric civilization, evidence of which was found during the excavations of a settlement at Akrotíri. The solid material and gases emerging from the volcano’s interior created a huge “vacuum” underneath, causing the collapse of the central part and the creation of an enormous “pot” –today’s Caldera– with a size of 8×4 km and a depth of up to 400m below sea level.
Santorini is one of the Cyclades islands in the Aegean Sea. It was devastated by a volcanic eruption in the 16th century BC, forever shaping its rugged landscape. The whitewashed, cubiform houses of its 2 principal towns, Fira and Oia, cling to cliffs above an underwater caldera (crater). They overlook the sea, small islands to the west and beaches made up of black, red and white lava pebbles.
