Abstract The 1956 Amorgos earthquake, with a magnitude of Ms = 7.5, caused a destructive tsunami in the Central Aegean Sea. Two gravity cores were collected south of Amorgos and Anafi Islands, respectively, confirming submarine landslide deposits linked to the 1956 earthquake. The 1956 Mass Transport Deposits (MTDs) vary in thickness from 55 to 100 cm in the cores. The predominant fraction of the sediments is clay, followed by sand (in the core next to Amorgos Isl.), while silt registers a maxim
