Field survey and coring campaign carrying out in the Pantano Morghella site (southernmost tip of Sicily) have allowed us to identify an anomalous sandy deposit within a clay sequence. Results from sedimentological, paleontological and X-ray analyses of the sandy deposit together with the reconstruction of its thickness, decreasing with distance from the sea, and its extension inland for about 1200 meters indicate that the sandy layer was likely deposited by a tsunami. Three radiocarbon dating constrain the age of sandy deposit in the interval 270-650 AD suggesting that it may represent the geological record of the 365 AD Crete tsunami.
