Minoan civilization especially the sequence of ceramic styles, have been used by archaeologists to define the three phases of Minoan culture (EM, MM, LM). Since wood and textiles have decomposed, the best-preserved (and most instructive) surviving examples of Minoan art are its pottery, palace architecture (with frescos which include landscapes), stone carvings and intricately-carved seal stones. Frescoes were the primary art form of Minoan culture. They include many depictions of people, with sexes distinguished by color; the men's skin is reddish-brown, and the women's white. Several frescoes at Knossos and Santorini survive. In contrast to Egyptian frescoes, Crete had true frescoes. Probably
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
