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.
Sea of Hyūga The Hyuga-nada Sea (日向灘 , Hyūga-nada ) is the part of the Pacific Ocean that lies off the eastern shore of the island of Kyushu, to the south-west of the island of Honshu, off the south coast of Japan. Its name is derived from the former province of Hyūga, which corresponded to the prefecture of Miyazaki before the Meiji Restoration.
