Short summary
Coastal and submarine landslides occur on average every 30–50 years at the western tip of the Gulf of Corinth. These landslides trigger tsunamis and thus represent a significant hazard. We realized an inventory of the submarine landslide deposits in the western Gulf. Six large events are identified in the last 130 000 years. Such sliding events likely generated large tsunami waves in the whole Gulf of Corinth, possibly larger than those reported in historical sources.
