The ash found on Crete is now known to have been from a precursory phase of the eruption, some weeks or months before the main eruptive phases, and it would have had little impact on the island. Santorini ash deposits were at one time claimed to have been found in the Nile delta, but this is now known to be a misidentification. The Minoan eruption is a key marker for the Bronze Age chronology of the Eastern Mediterranean world. It provides a fixed point for aligning the entire chronology of the second millennium BCE in the Aegean,
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
