Doggerland (also called Dogger Littoral) was an area of land, now submerged beneath the southern North Sea, that connected Great Britain to continental Europe. It was flooded by rising sea levels around 6500–6200 BCE, and its catastrophic flooding may have been the result of tsunami emanating from an avalanche in a Norwegian Fjord. Geological surveys have suggested that it stretched from what is now the east coast of Great Britain (in present-day Anglia) to what are now the Netherlands, the western coast of Germany and the peninsula of Jutland.
