Scientist say they've found out more about why a bit of land in the North Sea was abandoned thousands of years ago.

The area called Doggerland off the coast of England used to connect Britain to Europe thousands of years ago when sea levels were much lower than now.

Researchers believe a massive landslide off the coast of Norway caused a giant tidal wave five metres tall that wiped out the last people to live in Doggerland 8,200 years ago.
