Minoan civilization Santorini, which was entombed in a layer of pumice. Although it is believed to have severely affected the Minoan culture of Crete, the extent of its effects has been debated. Early theories proposed that volcanic ash from Thera choked off plant life on the eastern half of Crete, starving the local population; however, more-thorough field examinations have determined that no more than of ash fell anywhere on Crete. Based on archaeological evidence, studies indicate that a massive tsunami generated by the Thera eruption devastated the coast of Crete and destroyed many Minoan settlements. Although the LM IIIA (late Minoan) period
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
