Many researchers agree that the evidence points to the Island of Santorini, Greece.
A recent geological survey proves that before volcanic eruption destroyed the Island, its layout consisted of three circular concentric pits of seawater; and two earth-rings, each connected to the sea by a deep canal.
That corresponds exactly with the way ancient Greek philosopher Socrates described Atlantis!
Bonus Fact: the Santorini eruption is suggested by some researchers as a possible explanation for the biblical ten plagues.
For example, eruptions as such cover the skies with aches which can account for the darkness plague.
Second, when water is contaminated with sulfur it creates sulfuric acid, which, in turn paints the red. This can explain the blood plague and other plagues such beasts death of poisoning and the lice that burrows in dead animals.
Third, the contaminated acid rich water would have made frogs from river Nile to flee inland, which explains the frog plague.
Forth, the acid rain carried by the storm that usually follows huge eruption boils would have caused boils.
Notably, the Santorini mega-eruption dates back to what is assumed to be Moses
