What caused the Doggerland tsunami?

The tsunami that ripped across the North Sea around 6200BC, steamrolling coastlines from Norway to Scotland, resulted from the sudden collapse of some 180 miles (290km) of the continental shelf near Norway.

Was Doggerland catastrophically flooded by the Mesolithic Storegga tsunami?

Doggerland in the southern North Sea is a submerged landscape thought to have been heavily affected by a tsunami such that it was abandoned by Mesolithic human populations at the time of the event. The tsunami was generated by the Storegga submarine landslide off the Norwegian coast which failed around 8150 years ago.

How long did it take for Doggerland to disappear?

It was not until 700 years after the Storegga landslides — around 5500 BC — that the sea level rose so much that the North Sea engulfed the rest of the Dogger Bank. At that point, the island was completely submerged, and all traces of it vanished into the waves of the rough North Sea.

How quickly did Doggerland flood?

Another view speculates that the Storegga tsunami devastated Doggerland, but then ebbed back into the sea, and that later Lake Agassiz (in North America) burst, releasing so much fresh water that sea levels rose over about two years to flood much of Doggerland and make Great Britain an island.

What happened to Doggerland?

We know much of the polar ice melted, causing sea levels to rise around the world. By about 8200 years ago, Doggerland had gradually shrunk in size, leaving Dogger Island surrounded by a small archipelago (see image above). There is some evidence that this final piece of Doggerland had a dramatic end.

What if Doggerland still existed?

All of human history would be completely different. The Mesolithic people who originally inhabited Doggerland 10,000 years ago would not have had to retreat from the advancing sea. They would likely have stayed and multiplied in situ rather than redistributing their genes to the areas surrounding the North Sea.

What was life like 9000 years ago?

9,000 years ago (7000 BC): Jiahu culture began in China. 9,000 years ago: large first fish fermentation in southern Sweden. 9,000 years ago: Mehrgarh was Founded which is one of the earliest sites with evidence of farming and herding in South Asia.

Did humans live on Doggerland?

Digging Deep. In the early 1900s, not much was known about Doggerland. Some geologists believed it had been recently a landmass, but nothing was known of the people who lived there.

What was the last tsunami to hit Doggerland?

For years, scholars have proposed that a tsunami was the last big catastrophe to hit Doggerland before it was submerged. The new research suggests that the Storegga Event set off that tsunami. The Storegga Event was a series of underwater landslides that took place off the Norwegian Atlantic coast 8,150 years ago.

Where was the tsunami in the North Sea?

The scientists from the School of Life Sciences at the University of Warwick have been studying the sedimentary ancient DNA (sedaDNA) from sediment deposits in the North Sea for the past five years. They have now identified that the southern part of the North Sea, including the area of Doggerland, was hit by the tsunami 8,150 years ago.

How did the Storegga tsunami affect Great Britain?

What was the name of the land that was washed out by the tsunami?

The landmass that made the connection is called Doggerland. That land is now underwater and scientists have been working for years to find out what was the last big catastrophe to hit the hunter-gatherers living there before their prehistoric homes were washed away. A new study reveals that it was a tsunami.
