At the end of the MMII period (1700 BC) there was a large disturbance on Crete—probably an earthquake, but possibly an invasion from Anatolia. The palaces at Knossos, Phaistos, Malia and Kato Zakros were destroyed. At the beginning of the neopalatial period the population increased again, the palaces were rebuilt on a larger scale and new settlements were built across the island. This period (the 17th and 16th centuries BC, MM III-Neopalatial) was the apex of Minoan
Minoan eruption volcano, which erupted and then collapsed in an ongoing cyclical process. Immediately before the Minoan eruption, the walls of the caldera formed a nearly continuous ring of islands with the only entrance between Thera and the tiny island of Aspronisi. This cataclysmic eruption was centered on a small island just north of the existing island of Nea Kameni in the centre of the then-existing caldera. The northern part of the caldera was refilled by the volcanic ash and lava, then collapsed again. Research by a team of international scientists in 2006 revealed that the Santorini event was much larger than
