Caused a major tsunami along the Norwegian coast a few years back - 6100 BC (in an astronomical perspective this is ONLY A FEW YEARS BACK, I insist!)
The International Centre for Geohazards (ICG) carries out research on the assessment, prevention and mitigation of geohazards, including risk of landslide in soil and rock due to rainfall, flooding, earthquakes and human intervention, and the geological risks in deep waters, especially underwater slides. The Centre also contributes to the education of researchers and specialists in these fields.
The ICG network knows a whole lot about Storegga!
