Storegga Slide tsunami and Mesolithic Doggerland

Record summary

The Storegga submarine landslide off Norway generated a major tsunami that affected North Sea coasts, while postglacial sea-level rise progressively submerged Doggerland. Archaeological, geological and palaeoenvironmental research examines whether the tsunami caused abrupt local disruption within a longer process of inundation. The lead matters for comparing catastrophe narratives with dated sediment deposits, settlement changes and migration around shrinking habitable landscapes. Uncertainty concerns the tsunami’s precise regional impact, the degree of human demographic disruption and how different sediment layers are correlated.
