Well no, not really. But I found yet another place to look, and it's nice and difficult to look there. So maybe someone can get a book deal out of it: Atlantis is located about 1600 or 1700 nautical miles distant from Egypt, straight down. This distance is not too far out of whack with the original report, maybe the direction is. The timing of its sinking will have to be moved backwards by a few hundred million years, but we can do this by just moving the decimal point a little (nevermind that Plato didn't use one).
Where this comes from is
Seismic studies have found various parts of old continents (additonal links at the bottom of that article, some in english), sunken to the bottom of the earth's mantle. One of these is directly below the Med, this is the one I picked for Atlantis. Not sure when it sank, at least 500 million years ago.
What's new about these studies are mathematical (computer simulation) models of the convection in the mantle, caused by reactions of these sunken continents with the earth's outer core. Interesting consequences are that bits of the old continents get flushed upwards again, and come out to the surface in some magma, e.g. in Hawaii.
Also quite interesting is that the current continents are apparently (maybe?) only floating because of this convection, otherwise they would sink and we would have more than a few inches of sea level rise to worry about.
So that leaves stuff like, how would Plato know this? Of course he didn't, but we need to have a reason why he would. Without resorting to time travel and such, perhaps he was aware of theories of continental drift and subduction. Or he just made something up.
You know, this system really doesn't like long links as anchors, I always get these ugly line breaks. But if I literally post the whole link, the formatting breaks worse because of long unbreakable lines.
