Well, as the ice age ended, the climate became warmer and the sea level rose. The concentric waterways could have been designed to drain the land, and the rising ocean could have engulfed the continent and it appear that Atlantis sank. However, one would expect a very large shallow area just beneath the surface of the ocean. I was thinking that maybe the concentric waterways formed a cooling system for a mega-nuclear reactor or something like that. Maybe when the earthquake occurred, they had a mega-meltdown.
