How big was the Storegga Slide?
How big was the Storegga Slide?
Be that as it may, the Storegga Slide was one of the biggest tsunamigenic landslides that we know of, ever. Displacing about 3,200 cubic kilometers of sediment, “the Storegga slide is bigger than Scotland, and its headwall extends for about 300 kilometers.
When was the Storegga tsunami?
Around 8150 BP
Abstract. Around 8150 BP, the Storegga tsunami struck North-west Europe. The size of this wave has led many to assume that it had a devastating impact upon contemporaneous Mesolithic communities, including the final inundation of Doggerland, the now submerged Mesolithic North Sea landscape.
What was the Storegga tsunami?
Around 8,200 years ago, a massive multi-phase submarine landslide (the Storegga Slide) off the continental shelf of Central Norway caused a tsunami to hit the coastlines of west Norway, Scotland, and around the southern North Sea basin.
How big was the North Sea tsunami?
The wave that hit the north-east coast of Scotland is estimated to have been some 14m high, though it is unclear whether this area was inhabited at the time. But waves measuring some 5m in height would have hit the eastern coast of England, and there is good evidence humans were in this area 8,000 years ago.
What caused the Storegga Slide?
Storegga has been thoroughly investigated as part of the preparation activities for the Ormen Lange gas field off the coast of Norway. The prevalent conclusion is the slide was caused by glacial deposits left behind after the previous glacial period, making any recurrence only possible following a new ice age.
Where is Storegga?
the Norwegian Sea
Storegga (Norwegian: Great Edge) is located at the edge of Norway’s continental shelf in the Norwegian Sea, 100 km (62 mi) north-west of the Møre coast. In around 6200 BCE, structural failures of the shelf caused three underwater landslides, which triggered very large tsunamis in the North Atlantic Ocean.
Where was the worst tsunami in history?
Indonesia
Perhaps the most destructive tsunami in recorded history was the Indian Ocean Tsunami of 2004. A 9.1-magnitude earthquake occurred off the coast of Sumatra in Indonesia.
When was the first tsunami in the world?
The oldest recorded tsunami occurred in 479 BC. It destroyed a Persian army that was attacking the town of Potidaea in Greece. As early as 426 BC, the Greek historian Thucydides inquired in his book History of the Peloponnesian War (3.89.
What is HyNet?
HyNet is a real catalyst for clean growth. The project aims to lead the creation of a low carbon economy, protecting and creating local jobs to the North West and North Wales and across the UK. Inward investment will be attracted, establishing the region as a world leader in clean energy innovation.
Where are the Storegga Slides?
/ 64.867°N 1.300°E / 64.867; 1.300 The three Storegga Slides were large landslides. They occurred under water, at the edge of Norway ‘s continental shelf, in the Norwegian Sea. This is between Norway and Greenland, just north of Great Britain .
