Franck Goddio and his team from the IEASM were able to locate, map and excavate parts of the city of Thonis-Heracleion, which lies 6.5 kilometres off today’s coastline about 150 feet underwater in the Mediterranean.
Research suggests that the site was affected by geological and cataclysmic phenomena. The slow movement of subsidence of the soil affected this part of the south-eastern basin of the Mediterranean.
