Description :
Geo-scientific studies were carried out in the Livadi coastal plain and along the western coast of the inner Gulf of Argostoli. Terrestrial vibracorings and geophysical investigations brought insight into the local stratigraphical record. Geochronostratigraphical data were based on radiocarbon dating and the archaeological age estimation of diagnostic ceramic fragments. Geomorphological, sedimentological and geochemical methods were used to reconstruct the local palaeogeographical evolution and relative sea level changes since the mid-Holocene. Allochthonous sand sheets intersecting paralic swamp deposits and a mixture of badly sorted marine and terrestrial sediments document repeated tsunami landfall in the Livadi coastal plain. The results showed that tsunami impact has been of major significance for the overall Holocene coastal evolution of the Livadi coastal area. The local event-geochronostratigraphy found for the inner Gulf of Argostoli is in good agreement with results from studies in nearby coastal Akarnania and the western Peloponnese.
