: When the Storegga landslide occurred off the coast of Norway some 8000 years ago, it set off a massive tsunami that stretched all the way to Greenland. It may also have buried an ancient landmass called Doggerland that once existed in the North Sea and connected Great Britain with Europe. For several thousand years, Doggerland was home to Mesolithic tribespeople who hunted and fished in the area’s vast marshes and mudflats. As sea levels rose, Doggerland may have passed from being a land bridge to being an island. Researchers have determined that prehistoric bones and artifacts found in the waters of that area all predate the time of the landslide, which suggests that the tsunami may have wiped out the last people to occupy Doggerland.
