  3.600 years ago, the Strongyli volcano collapsed, creating the huge cauldron of the caldera. The Santorini Island complex, Thira, Thirasia, & Aspronisi, are the fragments that remained above the surface of the sea after the collapse, while the rest, the greatest portion of the island, disappeared under the water. Not long after the caldera was formed, molten rock, viscous magma with few gases, again began to flow up in the center of it, solidifying in contact with the seawater, building up a submarine volcanic structure which become the foundation of the Kameni Islets, Palea & Nea.
