An earthquake, not a volcanic eruption resulted in the inundation of Atlantis according to Plato’s account. Although, for those who believe that the destruction of ancient Santorini was the inspiration behind Plato’s Atlantis story, it is not difficult to imagine an earthquake accompanying an eruption such as that which occurred on Thera in the 2nd millennium BC, particularly in an area that had been prone to frequent earthquakes over thousands of years.
Earthquakes were once thought to be a form of divine retribution, so when an earthquake in 1570, causing death, damage and the alteration of the River Po’s course, ‘infallible’ Pope Pius V declared it to be the consequence of god’s wrath against the Jews!(b)
A PhD Dissertation by Jamie Rae Bluestone investigates early understanding of earthquakes, which inevitably touches on the Atlantis story(a).
A recent paper by Marc-Andre Gutscher discussed the Cadiz subduction zone, which appears to be ‘locked’ and consequently liable to generate very strong earthquakes over long return periods. Gutscher offered evidence of deposits dated to 12000 BC which ‘may correspond to the destructive earthquake and tsunami described by Plato’. However, he recognised that Plato describes a Bronze Age society, while Spartel Island in the Strait of Gibraltar would only have been inhabited by ‘simple fishermen’ unlikely to have merited a mention in the records of the Egyptian priests.
In the Mediterranean the Aegean and Turkey are most seismically active, followed by Italy (including Sicily)(f) and North Africa from Morocco to Tunisia. There is a European Earthquake Catalogue that graphically illustrates earthquake activity over the past 1,000 years(e). Italy is also home to most of the active volcanoes in the Med.
Ben Davidson, promotes the idea that earthquakes are caused by solar activity (c) and offers what he considers compelling evidence on a YouTube clip(d).
[The words ‘seismology’ and ‘epicentre’ were coined in 1858 by an Irishman, Robert Mallet (1810-1881)]
