Hill J, Avdis A, Mouradian S, et al., Was Doggerland catastrophically flooded by the Mesolithic Storegga tsunami?
Myths and legends across the world contain many stories of deluges andfloods. Some of these have been attributed to tsunami events. Doggerland in thesouthern North Sea is a submerged landscape thought to have been heavilyaffected by a tsunami such that it was abandoned by Mesolithic humanpopulations at the time of the event. The tsunami was generated by the Storeggasubmarine landslide off the Norwegian coast which failed around 8150 years ago.At this time there were also rapid changes in sea level associated withdeglaciation of the Laurentide ice sheet and drainage of its large proglaciallakes, with the largest sea level jumps occurring just prior to the Storeggaevent. The tsunami affected a large area of the North Atlantic leavingsedimentary deposits across the region, from Greenland, through the Faroes, theUK, Norway and Denmark. From these sediments, run-up heights of up to 20 metreshave been estimated in the Shetland Isles and several metres on mainlandScotland. However, sediments are not preserved everywhere and so reconstructinghow the tsunami propagated across the North Atlantic before inundating thelandscape must be performed using numerical models. These models can also beused to recreate the tsunami interactions with now submerged landscapes, suchas Doggerland. Here, the Storegga submarine slide is simulated, generating atsunami which is then propagated across the North Atlantic and used toreconstruct the inundation on the Shetlands, Moray Firth and Doggerland. Theuncertainty in reconstructing palaeobathymetry and the Storegga slide itselfresults in lower inundation levels than the sediment deposits suggest. Despitethese uncertainties, these results suggest Doggerland was not as severelyaffected as previous studies implied. It is suggested therefore that theabandonment of Doggerland was primarily caused by rapid sea level rise prior tothe tsunami event.
