Abstract

A high-energy deposit cuts through the early Holocene eolianites of the Sidi Salem Formation which forms a ridge along the southeastern coast of Tunisia. The sedimentary structures as well as the paleo-altitude and paleo-location of the outcrop state for a subaqueous deposition by an unusually large catastrophic event. Regarding its age and the related uncertainties, it could be either an exceptional storm, or a landslide or impact triggered tsunami. The mega-tsunami of the 8000 BP collapse of the Valle del Bove valley (Etna Volcano) could be this event, for its matching age and calculated run-up height.
