Santorini Geology

Volcanic eruptions
Special interest is drawn to Santorini and its geological formations. The island itself owes its very existence to the volcano. The present-day crescent shape of the island is a consequence of the activity of the volcano in prehistoric times.
The last huge eruption of the volcano dates back 3,600 years (17th century B.C.), to the late bronze age. Thirty million cubic meters of magma in the form of pumice and ash were blown to a height of up to 36 kilometers above the island. Pumice deposits, dozens of meters thick, buried one of the most prosperous pre-historic settlements of that period, feeding the myth of the lost Atlantis.
After this major eruption, a mild activity of the volcano continues into the present (the most recent eruption occurred in 1950) building up two small islands within the caldera, Palea and Nea Kameni. These islands represent the volcano’s most recent activity.

The only volcanic caldera accessible by boat
The marvelous dry climate and continuous sunshine create year around conditions which are perfect for observation, photographs and videos under an extraordinary variety of natural lights and colours. It is the island of Santorini that offers the visitor the unique and exceptional advantage of reaching the interior of a volcanic caldera by boat.
