Ping.
This theory has Atlantis in the wrong ocean.
Plato's description is pretty clear, and points to the most likely location -- just about where the Azores are now.
Thanks for the ping. I think he makes his point that Sundaland was inhabited before the rising sea level flooded it at the end of the last ice age, but not that Sundaland was Atlantis.
According to Plato, the destruction of Atlantis was a tectonic event that happened in a day and a night. Perhaps it was like the event that formed the Tula Rosa basin in New Mexico, in which the top of a mountain range suddenly dropped at least 4000 feet.
