Tsunamis are an often underestimated hazard in the Mediterranean Sea and parts of Europe . Of historical and current ( with regard to risk assumptions ) importance are the 1755 Lisbon earthquake and tsunami ( which was caused by the Azores – Gibraltar Transform Fault ) , the 1783 Calabrian earthquakes , each causing several tens of thousands of deaths and the 1908 Messina earthquake and tsunami . The tsunami claimed more than 123,000 lives in Sicily and Calabria and is among the most deadly natural disasters in modern Europe . The Storegga Slide in the Norwegian Sea and some examples of tsunamis affecting the British Isles refer to landslide and meteotsunamis predominantly and less to earthquake-induced waves
