Minoan civilization destroyed. The palace in Knossos seems to have remained largely intact, resulting in its dynasty's ability to spread its influence over large parts of Crete until it was overrun by the Mycenaean Greeks. After about a century of partial recovery, most Cretan cities and palaces declined during the 13th century BC (LHIIIB-LMIIIB). The last Linear A archives date to LMIIIA, contemporary with LHIIIA. Knossos remained an administrative center until 1200 BC. The last Minoan site was the defensive mountain site of Karfi, a refuge which had vestiges of Minoan civilization nearly into the Iron Age. The influence of Minoan civilization
Minoan eruption activity and the possible generation of tsunamis. Man-made structures not buried during Minoan A were completely destroyed. The third phase was also characterized by the initiation of caldera collapse. The fourth, and last, major phase (BO/Minoan D) was marked by varied activity: lithic-rich base surge deposits, lahars, debris flows, and co-ignimbrite ash-fall deposits. This phase was characterized by the completion of caldera collapse, which produced megatsunamis. Although the fracturing process is not yet known, the altitudinal statistical analysis indicates that the caldera had formed just before the eruption. The area of the island was smaller, and the southern and eastern
