We are investigating the effects of earthquakes and tsunamis on the sedimentary record in the Ionian Sea through the analysis of turbidite deposits. A comparison between radiometric dating and historical earthquake catalogs suggests that turbidite emplacement triggered by great earthquakes represents over 90% of the deposits in this region. Seismo-turbidite beds can be correlated with major earthquakes such as the AD 1908 Messina, AD 1693 Catania, AD 1169 Eastern Sicily and AD 365 Crete earthquakes.
