Abstract

Giant submarine landslides in the Storegga area on the continental slope west of Norway took place on at least three occassions during the Late Quaternary. This paper provides a summary of present knowledge regarding tsunamis generated as a result of the Storegga Slides. Most attention, however, is given to the tsunami generated by the Second Storegga Slide that took place circa 7,000 years ago. The tsunami generated by this landslide is believed to have struck most coastlines bordering the eastern North Atlantic. The paper summarises the geological evidence for the former occurrence of this tsunami. These results are compared with the results of recent mathematical modelling of the landslide and tsunami. Remarkably, there is relatively good agreement between estimates of tsunami run-up derived from the sedimentary evidence and run-up values obtained from the modelling experiments.
