Stratigraphic and geomorphological analysis as a basic tool for the creation of marine ingression maps applications in the central Sicily Channel (Southern Italy)

The assessment of the vulnerability of a site to tsunami events should take into consideration the geomorphological setting, strongly determined by the stratigraphic framework of the area. The island of Lampedusa is located in the central portion of the Sicily Channel (Mediterranean Sea, Italy), where a significant incidence of tsunamis (with run up above 15 m) caused by earthquakes and submarine landslides is historically documented. Supported by an updated stratigraphic characterization of the island, this work shows the geomorphological differences between the western and south-eastern sectors of the Lampedusa island and analyzes the expected scenarios of marine ingression according to run-up steps of 5, 10 and 15 m.
