Humans lived in Doggerland from around 10,000 BC until it was flooded at the end of the last ice age around 7,500 years ago. Recently a team at Imperial College showed that the later island of Doggerland was flooded in a single titanic event around 8000 years ago. A tsunami, with waves up to five metres in height, was triggered by a huge landslide off the coast of Norway. For hundreds of years, trawlermen fishing off the coast of Dogger Bank have pulled up finds and mammoth bones in their nets.
