Santorin telle qu'elle est dessine aujourd'hui est le rsultat d'une des plus importantes ruptions volcaniques de l'Antiquit, ayant eu lieu autour de 1640 av. J-C, et dont le cataclysme dvastateur qui ravagea une bonne partie de la Mditerrane de l'Est fut l'origine du mythe de l'Atlantide.
Le cratre du volcan, creus par une succession d'ruptions volcaniques majeures remontant plus de deux millions d'annes, est compos de cinq les distinctes : Na Kamni, Pala Kamni, Thrasia, Aspronissi, et Thra, l'le principale en forme de demi-lune, au creux de laquelle se nichent le port principal et la ville de Fira.

Santorini, named by early Venetians in honor of Saint Irene, forms a circular group of islands belonging to the Cyclades island chain in the southern Aegean Sea, located midway between mainland Greece to the west, Turkey to the east, and the island of Crete to the south. The Cyclades form part of the Aegean island arc system, generated by northward subduction of the African plate along the arcuate Hellenic trench system located south of Crete. Within this plate-tectonic setting, the ring-shaped group of islands known as Santorini includes Thera (the largest), Therasia (little Thera), Aspronisi, and the central Kameni Islands.
The islands of Santorini did not form from a single event, but rather from a variety of eruptions over a long period of time. Geologic studies indicate that at least 12 eruptive phases have occurred over the last one million years. The late Bronze Age event was a Plinian eruption of epic proportions, with an estimated Volcanic Explosivity Index (VEI) of 6.9. The immensity of this eruption is equaled or surpassed by only seven other terrestrial eruptions in the past four millennia. Before this catastrophe, Santorini was a large circular island with a water-filled embayment to the south or southwest. During the late Bronze Age eruption, the central highland of the volcanic island collapsed to generate the modern caldera.
