Plato's Erosion Event and the Subsidence of Atlantis

The popular version of the Atlantis story fixates on the submergence, the island going under in a single catastrophic day and night. But if you actually go back and read what Plato wrote, the account is more layered than that, and the details that get glossed over are precisely the ones worth examining. There was a war before any of this happened. A civilization based outside the Straits of Hercules had been pushing inward, subjugating the peoples of the Mediterranean. What Plato describes as proto-Athenians organized a resistance, drove the Atlanteans back, and it was only in the immediate aftermath of that conflict that the geological catastrophe occurred.

Here is the detail almost everybody misses. Plato does not describe the subsidence of Atlantis in isolation. He ties it directly to a severe erosional episode on the Greek peninsula itself, a landscape-scale stripping of soil and vegetation that left the bedrock exposed. If you have a catastrophic subsidence event in one location and a severe erosional event in another happening simultaneously, you are not looking at something localized. You are looking at a broad regional disturbance, and that description maps considerably more naturally onto the Younger Dryas impact hypothesis than onto any conventional tectonic explanation.
