The 365 Crete earthquake occurred at about sunrise on 21 July 365 in the Eastern Mediterranean, with an assumed epicentre near Crete. Geologists today estimate the undersea earthquake to have been a moment magnitude 8.5 or higher. It caused widespread destruction in the central and southern Diocese of Macedonia, Africa Proconsularis, Egypt, Cyprus, Sicily, and Hispania (Spain). On Crete, nearly all towns were destroyed.
