Santorini_Travel Tips_2The small archipelago is still an active volcano and probably the only one in the world whose crater is in the sea. After a huge volcanic explosion in 1400 A.D. the central parts of a formerly single circular island were greatly destroyed (the present-day crescent shape of Thíra is a consequence of the activity of the volcano of that time) and at that place the current geological caldera was created. What remains today is chiefly a water-filled caldera whose depth is up to 400 metres below the sea level and whose size is 8x4km.
