Doggerland was submerged by a tsunami formed in what ocean?
Doggerland Doggerland was an area now beneath the southern North Sea that connected Great Britain to continental Europe during and after the last glacial period. It was flooded by rising sea levels around 6,500–6,200 BCE. Geological surveys have suggested that it stretched from Britain's east coast to the Netherlands and the western coasts of Germany and the peninsula of Jutland. It was probably a rich habitat with human habitation in the Mesolithic period, although rising sea levels gradually reduced it to low-lying islands before its final submergence, possibly following a tsunami caused by the Storegga Slide.
Eemmeer The Eemmeer (] ) is a lake situated in the middle of the Netherlands between the provinces of Flevoland, Utrecht, and North Holland. It measures 13.4 km2 and contains one small island, the Dode Hond ("Dead Dog"). The Eemmeer is one in a series of peripheral lakes used to geohydrologically detach the low-lying polders of Flevoland from higher old mainland. The Eemmeer is connected to the peripheral lakes Gooimeer in the west, at the point where both lakes are crossed by the highway A27 bridge, and the Nijkerkernauw in the east.
