Mike Tryon All Messages By This Member #7737 The original research paper that this news item is based on is here: The newspaper headline is clearly meant to attract attention rather than convey the conclusions of the study. The very well studied Storegga Slide of 8150 BP, caused a large tsunami which resulted in wave heights of 2-4 meters along the coast of Scotland. The associated run-up of many kilometers likely inundated coastal mesolithic communities and caused significant loss of life and resources. This may have contributed to short-term population decline in coastal Scotland, coinciding with a much broader population decline associated with a period of decreasing global temperature that began about 8200 BP and lasted for a few hundred years.

All Messages By This Member #7738 开云体育 Maybe this is the origin of the story later told by Plato and learned from priests in Ancient Egypt that relates to the destruction of Atlantis “beyond the pillars of Hercules” (Gibraltar).? Speculative but perhaps it became a story that was retold over generations.

Iain All Messages By This Member #7739 开云体育 I went for a walk over some of those deposits this morning. The effects on my particular part of eastern Scotland were very mild. The tsunami came from the north and it's not until you reach Shetland that you get 65ft waves. The Storegga Slides have also been credited with the final demise of Doggerland, and would have caused massive disruption to coastal communities around the North Sea. The further north you go, the more the impact would have been felt, as waves were higher and communities become more coastal. A key finding from this new study is that the result could only be replicated by a high tide (in Northumberland), which presumes close to a low tide in either Shetland or the Thames Estuary, or close to a low tide in both. High tide brings greater inundation of the land; but low tide was a time for foraging on the seashore, potentially bringing greater mortality. The tsunami occurred in late autumn, and people may still have been collecting kelp or shellfish. River and marine flood mythologies are common across the ancient world, though their details vary as much as the causes of flooding. Various marine transgressions have been proposed for these stories, including the Atlantis myth. Storm surges are also a frequent occurrence in the British Isles and can lead to substantial mortality and damage even in modern times (e.g. the 1953 North Sea floods). The south-west was also affected by the 1755 Lisbon earthquake tsunami. The origins of these would have remained a mystery to local residents and (as with the 1607 Bristol Channel floods) were normally interpreted as divine punishment, creating the perfect scenarios for such myths to arise. - Iain.
Piero Sinclair #7740 Despite my facile comment I think this subject fascinating. Thanks Iain. toggle quoted message Show quoted text On Thu, 25 Jan 2024, 09:51 Iain via , <gubbins=[email protected]> wrote: I went for a walk over some of those deposits this morning.
