Atlantis covered with rising seas rather than going down due to earthquakes

In his book Atlantis: The Lost Continent Finally Found author Professor Arysio Santos points out that in 11,600 B.C., around the time Plato said Atlantis existed, and at the end of the last ice age, the sea level was 500 feet lower than it is today. That is because much more of the water on earth was bound up in ice than it is now. Professor Santos concludes that Atlantis had to be in present-day Indonesia in the South China Sea since there is submerged land there that would have been above sea level at the end of the last ice age.
