Tsunami de #Storegga (6200 a.C.)
Aunque más antiguo, nuevos estudios en 2023 han reevaluado su impacto:
- Origen: Deslizamiento submarino en #Noruega.
- Evidencias recientes:
- Depósitos en el Mar del Norte y Escocia confirman olas de 20 metros.

Beautiful view of #Stavanger from the air. Also nice for me to see #Kvitsøy (I have been running simulations of #tsunami runup there from the #Storegga event.)

New Open Access paper in Nature Communications: Contamination of 8.2 ka cold climate records by the Storegga tsunami in the Nordic Seas by Stein Bondevik, Bjørg Risebrobakken, Steven J. Gibbons, Tine L. Rasmussen, Finn Løvholt Volume 15 Issue 1 Pages 2904 Date 2024-04-04 DOI 10.1038/s41467-024-47347-9 The 8200-year BP cooling event is reconstructed in part from sediments in the Norwegian and North Seas. Here we show that these sediments have been reworked by the Storegga tsunami – dated to the coldest decades of the 8.2 ka event. We simulate the maximum tsunami flow velocity to be 2–5 m/s on the shelf offshore western Norway and in the shallower North Sea, and up to about 1 m/s down to a water depth of 1000 m. We re-investigate sediment core MD95-2011 and found the cold-water foraminifera in the 8.2 ka layer to be re-deposited and 11,000 years of age. Oxygen isotopes of the recycled foraminifera might have led to an interpretation of a too large and dramatic climate cooling.
