Michael Hubner claimed Atlantis was overwhelmed by a tsunami, which then receded leaving the remains undiscovered, near the coast of Marrakesh.
The German computer expert formed his theory using mathematics to calculate the precise GPS coordinates of the lost city.
He meticulously gathered every detail he could from Plato's 'Timaeus' and 'Critias' which describes Atlantis in detail and gives in total 51 clues about the mysterious city.
These 'clues' include that Atlantis was near the sea and had a ring-like structure surrounding its centre. Crucially, it was also said to be 3,100 miles from Athens. This area includes Europe, Africa and the Middle East.
Other clues were that Atlantis was not in ancient Europe or Asia and had very high and big mountains, with Morocco having the Atlas mountains. It was also said to lay west of Egypt and Tyrrhenia.
Using these details Hubner put the measurements into a computer programme and used a map which divided the area into 400 squares.
Hubner marked the areas where more characteristics were present and came out with one region which had the most clues - the Souss Massa plain in Morocco, about 100 miles south of Marrakesh.
He then took the GPS coordinates and went to have a look himself.
What he found appeared to have many of the attributes of Atlantis described 2,600 years ago by Plato, regarded as one of the greatest Western thinkers.
The site was in a desert basin just seven miles from the sea and in the centre was a small mound, similar to the raised area at the heart of the ancient city described by Plato.
Surrounding it were circular dry riverbeds, matching Plato's description of the city being surrounded by concentric circles, which alternated between land and sea.
Hubner concluded it was highly improbable that all the characteristics of Atlantis were present in this area purely by chance.Sort of like Heinrich Schliemann's discovery of Troy--he decided that the legend had some truth and followed the clues.
