Archaeologist Olga Krzyszkowska agreed: "The stark fact is that for the prehistoric Aegean we have no direct evidence for war and warfare "per se"." Between 1935 and 1939, Greek archaeologist Spyridon Marinatos posited the Minoan eruption theory. An eruption on the island of Thera (present-day Santorini), about from Crete, occurred during the LM IA period (1550 - 1500 BC). One of the largest volcanic explosions in recorded history, it ejected about of material and was measured at 7 on the Volcanic Explosivity Index. The eruption devastated the nearby Minoan settlement at Akrotiri on
Minoan chronology which became indispensable for any department of classical archaeology. On Evans' death in 1941, the British School of Archaeology assumed responsibility for the excavation, later turning the property over to the Greek government, while retaining excavation rights. Evans' chronological framework had triple divisions each triply divided, a formula that has been retained, thus Early Minoan (EM) I, II and III, Middle Minoan (MM) I, II and III etc. Each subsection he divided into A and B, early and late. In 1918 Alan J. B. Wace and Carl Blegen adapted Evans' chronology to the Greek mainland and the islands, where the
