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. Storegga slides, series of submarine landslides in the Norwegian Sea that occurred between approximately 8,400 and 2,200 years ago. The combined activities of these landslides produced a scar on the seafloor that begins some 100 km (60 miles) off Norway's More Coast on the edge of Europe's

The Storegga Slide is the largest known exposed submarine landslide in the world, which triggered a tsunami that inundated the coasts of northern Europe ~8,150 years ago. Previous studies. Storegga Submarine Landslide: The Storegga Slide is the largest-known submarine landslide. It occurred in the Norwegian Sea about 8200 years ago. The slide triggered a tsunami that produced significant run-ups on the west coast of Norway, Scotland, the Shetland Islands, and the Faroe Islands. ADVERTISEMENT 1. Introduction The Storegga Slide ( Fig. 1) is one of the largest submarine slides discovered, and has been known since the 1970s ( Bugge, 1983 ). Recent studies conclude that the slide occurred as one main event 8200 years ago and removed between 2500 and 3500 km 3 of sediment from the slide scar ( Haflidason et al., 2005 ). July 5, 2021 by David Nikel Home » History Blog » The Historic Storegga Slide & Tsunamis The three Storegga slides were among the largest ever known submarine landslides. They caused massive tsunamis that permanently changed the map of Northern Europe. When talking of tsunamis in and around Norway, many people know of the Tafjord tsunami.
The Historic Storegga Slide & Tsunamis Life in Norway
The Storegga Slide presents a unique opportunity to obtain stringent bounds on the slide dynamics from back calculations of both the tsunami (through available paleo-tsunami runup heights) and landslide runout (from seabed observations). Moreover, the Storegga Slide is well suited for testing the effect of remolding, as this landslide went. The Storegga event is one of the largest submarine landslides known in the world and is located off the coast of Norway. It occurred about 8,150 years ago, after the end of the last ice age, and.

Coordinates: 64°52′N 1°18′E. 64°52′N 1°18′E. Position of the slides. The three Storegga Slides were large landslides. They occurred under water, at the edge of Norway 's continental shelf, [1] in the Norwegian Sea. This is between Norway and Greenland, just north of Great Britain . Height of tsunami wave.

Tsunami waves triggered by the Storegga Slide at ~8200 years ago 59 were recently recognized to be 0.5-4.5 m higher in the southeast North Sea near Denmark 15, and 20 m higher around the. The Storegga Slide (Fig. 1) is one of the largest submarine slides discovered, and has been known since the 1970s (Bugge, 1983). Recent studies conclude that the slide occurred as one main event 8200 years ago and removed between 2500 and 3500 km 3 of sediment from the slide scar (Haflidason et al., 2005).
The Storegga Slide off mid Norway created the most pronounced exposed slide-scar on the European margin. It stretches from the North Sea Fan in the south to the Vøring Plateau in the north. With an overall volume of approximately 5,580 km 3 of mass removal, and a total affected area of 112,000 km 2 , this slide is the world's largest exposed. Fig. 1. Location of the Storegga slide. The slide area has been extensively mapped and investigated in connection with petroleum exploration and especially in connection with the slide risk evaluations for the Ormen Lange gas field.

The giant Storegga Slide has been a well-known feature since the 1970s ( Bugge et al., 1988 ). It occurred at about 8100 cal. years B.P., and affected a total area of 90,000 km 2. The headwall is approximately 300 km long and the total slid volume is nearly 3500 km 3. The pre-slide slope in the Storegga area was in the order of 0.5-1.0°.
