Britain’s separation from Europe was triggered by several mega-tsunamis around 8,000 years ago resulting from the Storegga Slide, an international team of researchers have revealed in a study published in the journal Geosciences.
The Storegga Slide was a landslide off the continental shelf off Norway which occurred around 6225–6170 BC, leading to the submarine collapse of hundreds of kilometers of coastal land.
Citing evidence based on geochemical signatures, lithostratigraphy, sedimentary ancient DNA and other data, scientists have been able to prove that tsunamis resulting from the slide led to the submergence of Doggerland – and thus the separation of Britain from the rest of the continent.
Doggerland is believed to have been mostly uninhabitable during the last Ice Age, but as the ice melted, plant and animal activity started to emerge on the land – and eventually humans appeared there during the Mesolithic period. No border issues between Britain and Europe existed back then.
As the ice melted, sea levels were rising too, causing the land’s eventual submergence even before the catastrophic Storegga Slide. By 9,000 BC, Britain could have already been separated from the continent, but some landmass probably still existed.
It seems that it was not Brexit and anti-EU sentiment that first separated Britain from Europe, but rather rising sea levels and mega-tsunamis.
