How big was the Storegga tsunami?
How big was the Storegga tsunami?
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 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.
What is Storegga?
Storegga is the Old Norse word meaning “great edge.” The scar caused by the slides spans an area of approximately 95,000 square km (about 36,700 square miles) and contains 2,400–3,500 cubic km (576–840 cubic miles) of sediment. Traces of tsunami-delivered sediment also occur in Iceland, Norway, and the Faroe Islands.
When was the Storegga slide?
6100 BC

Can Scotland have a tsunami?
Ancient Scottish tsunami could destroy entire towns if it happened today, new study finds. A new study led by researchers at the Universities of Sheffield, St Andrews and York has revealed that the Storegga tsunami that hit Scotland’s coastline 8,200 years ago, could devastate entire towns if it happened today.
How tall was the tsunami in the Storegga Slides?
Some models of the Storegga slides estimate that tsunami waves exceeded 20–25 metres (65–80 feet) in height along the coast of the Shetland Islands, 10–12 metres (33–39 feet) along the Norwegian coast, and 5 metres (16 feet) along the coast of eastern Scotland.
Where was the location of the Storegga Slide?
The three Storegga Slides are considered to be amongst the largest known landslides. They occurred under water, at the edge of Norway’s continental shelf (Storegga is Norwegian for “the Great Edge”), in the Norwegian Sea, 100 km (62 mi) north-west of the Møre coast, causing a very large tsunami in the North Atlantic Ocean.
How tall does a tsunami have to be to pass under a ship?
Traditional tsunamis have a small wave height offshore and generally pass unnoticed at sea, forming only a slight swell on the order of 30 cm (12 in) above the normal sea surface. In deep water it is possible that a tsunami could pass beneath a ship without the crew of the vessel noticing.
When did the Storegga Slides in the Norwegian Sea happen?
Storegga slides, also called Storegga landslides, series of submarine landslides in the Norwegian Sea that occurred between approximately 8,400 and 2,200 years ago.
