Minoan eruption is debated. Early theories proposed that ashfall from Thera on the eastern half of Crete choked off plant life, causing starvation of the local population. However, after more thorough field examinations, the theory has lost credibility, as it has been determined that no more than of ash fell anywhere on Crete. Other theories have been proposed based on archeological evidence found on Crete indicating that a tsunami, likely associated with the eruption, impacted the coastal areas of Crete and may have devastated the Minoan coastal settlements. Another theory is that much of the damage done to Minoan sites resulted from
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
