Minoan civilization activity (in the Cyclades and the Argolid/Attica). 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 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
