That’s a very well written and researched article and a compelling thesis. The timeline corresponds roughly with one of the Lake Agassiz GLOFs and earthquakes often create tsunamis. Therefore “one grievous day and night” could have been meant literally for the destruction of a coastal city and not poetic. Just look at Rungholt, Phuket or the region around Fukushima. If a Lake Agassiz GLOF was responsible the flood would not have receded. To tell the truth, I am not really concerned about the exact location of Atlantis. The flood events and the rise of the sealevel of about 120m at the end of the last ice age would have submerged a lot of coastal settlements and cities. Not just in the Mediterranean and the Black Sea but all around the world. Logic dictates, that Plato’s story is based on a real event. The Cyclades Plateau is a first class candidate for a lost culture.
