Seems to me that if there is a city down there, it needs to be investigated - whether it is Atlantis or not.
The mainstream archaeologists don't seem to be giving this much attention and in fact, Mr Sarmast himself says,"We can expect to find colossal buildings, bridges, roads, canals and stone temples." I don't think he has found anything but geological features on the ocean bed so far. None-the-less, I'm hopeful.
All the shifting of the weight from the water would have caused large earthquakes and probably volcanos too.
