Santorini: The Mystery of the Ancient Volcano That May Have Inspired Atlantis   The Atlantic - August 10, 2018
An olive branch that comes from the Greek island of Santorini, where a volcano erupted more than three millennia ago, spewing gas, ash, pumice, and boulders into the sky. Once depleted, the volcano collapsed in on itself. So violent was the eruption, some have speculated, that it ended the once prosperous Minoan civilization, instigated a volcanic winter as far away as China, and inspired the 12 plagues of Exodus as well as the myth of Atlantis - claims that are to varying degrees controversial. But nothing is as controversial, it turns out, as the debate over when the Santorini volcano actually erupted.

Prehistoric North Sea 'Atlantis' hit by 5m tsunami   BBC - May 1, 2014, 2014

A prehistoric Atlantis in the North Sea may have been abandoned after being hit by a 5m tsunami 8,200 years ago. The wave was generated by a catastrophic subsea landslide off the coast of Norway. Analysis suggests the tsunami over-ran Doggerland, a low-lying landmass that has since vanished beneath the waves. The wave could have wiped out the last people to occupy this island.

Doggerland is a name given by archaeologists and geologists to a former landmass in the southern North Sea that connected the island of Great Britain to mainland Europe during and after the last Ice Age, surviving until about 6,500 or 6,200 BCE and then gradually being flooded by rising sea levels. Geological surveys have suggested that Doggerland was a large area of dry land that stretched from Britain's east coast across to the present coast of the Netherlands and the western coasts of Germany and Denmark. Doggerland was probably a rich habitat with human habitation in the Mesolithic period, although rising sea levels gradually reduced it to low-lying islands before its final abandonment, perhaps following a tsunami caused by the Storegga slide.
