The Central Mediterranean is a very geologically unstable region containing as it does all of Europe’s land-based active volcanoes(a), regular seismic(b) activity with the attendant risk of tsunamis. It is now estimated that a devastating tsunami will hit the Mediterranean every 100 years(c). While the Aegean region experiences the greatest number of earthquakes, the Central Mediterranean, particularly around Sicily is also prone to regular tremors.
The idea that Atlantis was situated in this region is advocated by a number of researchers, including Alberto Arecchi, Férréol Butavand, Anton Mifsud, Axel Hausmann, as well as this compiler. Plato unambiguously referred to only two places as Atlantean territory (Crit.114c & Tim 25b) North Africa and Southern Italy as far as Tyrrhenia (Tuscany) plus a number of unspecified islands.
The area between Southern Italy and Tunisia has had a great number of sites proposed for the Pillars of Herakles, while possible locations for Gades are on offer with a number places still known today by cognates of that name.
Plato clearly includes continental territory as part of the Atlantean domain as well as a number of important islands. Within a relatively small geographical area, you have two continents, Africa and Europe represented by Tunisia and Italy respectively, as well as the islands of Sicily, Sardinia, Corsica and Malta together with a number of smaller archipelagos, matching Plato’s description exactly. The later Carthaginian Empire also occupied much of the same territory apart from eastern Sicily and southern Italy which by then was controlled by the Greeks and known as Magna Graecia.
For me, the clincher is that within that region we have the only place in the entire Mediterranean to have been home to elephants up to Roman times – Northwest Africa.
