Did you know that the whole complex of Santorini islands is still an active volcano (the same as Methana, Mílos and Nisiros) and probably the only volcano in the world whose crater is in the sea?
Santorini is a remarkable natural wonder that features a world-renowned volcano. This magnificent sight and attraction played a significant role in the formation of the island, shaping its current structure and geomorphology through a massive volcanic eruption that occurred thousands of years ago.
Crescent-shaped Santorini (or Thira), the precious gem of the Aegean, is actually a group of islands consisting of Thira, Thirassia, Aspronissi, Palea and Nea Kameni in the southernmost part of Cyclades.
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.
