During the last millennium and more, humans have suffered many disasters caused by the sea: storm surges erased whole settlements, for example, at the German coasts, and humans temporarily moved out of the coastal zone for many decades. Tsunamis destroyed cities, for example, the earthquake and tsunami in Lisbon in 1755. The scale of the event becomes clear from the shock it brought to Europe and its noticeable impact on culture and philosophy. The background picture is one of the many art pieces that depicted the horror associated with this event.
