The caldera of Santorini is the gulf surrounded by the roughly crescent-shaped island. This caldera formed when the island underwent a cataclysmic volcanic eruption between 1500 and 1700 BC. The eruption drained so much magma from the chamber beneath Santorini that most of the island collapsed into the space left behind and disappeared beneath the sea.
The volcano is situated on a small island (Nea Kameni) from the Santorini archipelago, in the South Aegean Sea; 36024' North latitude and 25024' East longitude. The island is part of insular Greece (some 200 km away from the Greece mainland and 110 km north of Crete). Santorini (ancient name was Thira) is one of the most beautiful Greek islands.

Santorini volcano is on a convergent plate boundary where the African Plate is subducting beneath the Eurasian Plate. This tectonic setting has created volcanic activity in the region, leading to the formation of Santorini island.
There has been evidence of at least 12 major eruptions of Mount Santorini in the past 200,000 years. The most famous eruption occurred around 1600 BC, leading to the collapse of the Minoan civilization on the island of Crete. Since then, the volcano has had smaller eruptions and is still considered active today.
