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 few months' warning. Since no human remains have been found at the Akrotiri site, this preliminary volcanic activity probably caused the island's population to flee. It is also suggested that several months before the eruption, Santorini experienced one or more earthquakes, which damaged the local settlements. Intense magmatic activity of the first major phase (BO/Minoan A) of the eruption deposited up to of pumice and ash, with a minor lithic component, southeast and east. Archaeological evidence indicated burial of man-made structures with limited damage. The second (BO/Minoan B) and third (BO/Minoan C) eruption phases involved pyroclastic flow and lava fountain
