Haverkamp, Wolfgang
Wolfgang Haverkamp is a German writer who firmly places Atlantis on the Mid-Atlantic Ridge(a). He claims that the area of the island was 80% that of the Iberian Peninsula. He suggests that the demise of Atlantis may have been the consequence of a pole shift following an encounter with an extraterrestrial body by the earth.
