Volcanism is not part of the Atlantis story as related by Plato. His narrative clearly attributes the destruction of Atlantis and the Athenians to flooding and earthquake. Admittedly, flooding can be the result of some volcanic activity, but in the absence of any evidence to support this view in the case of Atlantis, the idea is only supposition. While most accept that Atlantis was named after its first king, Atlas, Frank Joseph’s fertile imagination suggests that ‘the island of Atlantis was named after its chief mountain, a dormant volcano’. For those that place Atlantis in the Atlantic the idea of volcanic or seismic activity as the cause of the flooding of Atlantis AND Athens are hard pressed to suggest a location for this activity that would explain two catastrophes two thousand miles or more apart.
However, the red, white and black stone that Plato may be related to volcanic eruptions that produce rock of tufa (red), pumice (white) and lava (black). Pumice has been found at various locations in Egypt and identified as originating not only from Thera, but also from eruptions on the Greek islands of Nisyros and Giali as well as the Italian Lipari Islands(o).
Jelle Zeilinga de Boer and Donald Sanders are the authors of Volcanoes in Human History in which they support the idea that the eruption on Thera was a factor in the development of the Atlantis story and also suggest a link with the Flood of Deucalion.
Nevertheless, a recent book by William Lauritzen, The Invention of God, makes a convincing case for accepting volcanic activity as the inspiration behind some of the imagery of ancient mythologies and most major religions. A recent article(i) on the BBC website expanded on this further. Lauritzen also suggests that the pyramids were meant to represent volcanoes.
The most active volcanic region of Europe is to be found in Italy, where Etna and Stromboli have been continuously erupting for thousands of years(b). There is a report that a 6000 BC extreme eruption of Etna resulted in a tsunami 130 feet in height which swept the Mediterranean(c). However, the most devastating prehistoric volcanic eruption discovered so far seems to have been in Siberia 252 million years, which may have led to the most extensive mass extinction of life on earth(e). This is now rivalled by Tamu Massif in the Pacific mentioned below.
The cataclysmic volcanic eruption of Thera in the second millennium BC has had a strong level of support as the cause of Atlantis’ collapse, a view endorsed by recent television documentaries and an IMAX film. The Greek volcanologist, George Vougioukalakis, whose research is featured in the aforementioned film, is convinced that the eruption of Santorini offers the most rational explanation for the truth behind Plato’s story(a). However, he dissents from the recently expressed view that pumice found on the Northern Sinai Peninsula was transported there by a tsunami generated by the eruption of Thera and prefers to believe their transportation there was by normal sea currents.
Apart from Santorini, Jim Allen had initially proposed the Andean village of Quillacas, which lies on top of a volcano, as the site of Atlantis, but later found that the nearby site of Pampa Aullagas had a greater correspondence with the description of Atlantis. More recently Richard W. Welch has suggested the eruption of a supervolcano in the Atlantic as the cause of Atlantis’ demise. And so the idea of a volcanic destruction of Atlantis still has some support!
Since January 2011, Santorini has shown some signs of a volcanic reawakening(d).
In September 2013 studies revealed(f) what may be the location of the largest volcano ever to have erupted on our planet. It would have been the size of the British Isles and situated underwater in the northwest Pacific and known as Tamu Massif. It would have rivalled the Olympus Mons on Mars, but fortunately, has been dormant for 140 million years.
March 2014 saw a post on Dale Drinnon’s website(g) take the linkage between Atlantis and a volcano rather further with the suggestion that “the capital city of Atlantis in Plato’s description was built in the caldera of an extinct volcano and that many of the features of the description are volcanic in origin.The “Poseidon’ temple is the pyramidal volcanic neck, an erosional feature that stood out like a conical mound some hundreds of feet in diameter and possibly some hundreds of feet high on the outside. there was a tunnel bored through this aligned East and West, to allow the sunlight in at the beginning and the end of the day for certain rituals.”
In December 2014 a report from Princeton University revealed that a massive series of volcanic eruptions 66 million years ago can be aligned with the extinction of the dinosaurs and should be included as part of the cause of that extinction along with the Yucatan meteorite impact(h).>However, in February 2021, a report from Harvard proposed that the Yucatan impactor was a comet rather than an asteroid or meteor(s).<
In 2009, it was reported(q) that another example of contemporaneous meteorite impact and flood volcanism was identified in Belarus.
The Laki volcano in Iceland erupted in 1783, killing 9,000 local people but more dramatically causing the Nile Valley population to be cut by a sixth, according to a study published by scientists at Rutgers, The State University of New Jersey. “The study is the first to conclusively establish the linkage between high-latitude eruptions and the water supply in North Africa”(j).
A 2015 report(k) suggests that a series of North American volcanic eruptions in 536 AD had such a detrimental effect on the climate of Europe that contributed to the demise of the Roman Empire.
Furthermore, there is now evidence(m) that the eruption of El Chicon volcano in Southern Mexico around 540 AD led to the disruption of the Maya civilisation. Can there be a connection between these two events? In 2020, it was reported that the massive Tierra Blanca Joven eruption of the Ilopango volcano in El Salvador had been accurately dated to within a year or two of 431 AD, which also devastated Maya communities within an eighty kilometre radius(r).
However, David Keys in his book, Catastrophe, has proposed that a massive eruption of Krakatoa around 535 AD caused disruption on a global scale. Matthew Toohey from the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, has suggested the possibility of a double event involving both El Chicon and Krakatoa!
Recently the longest (1,200 miles) continental volcano chain was identified in Australia(l).
The BBC reported(n) in 2016 that “Deep-sea volcanoes are so remote, until recently we did not even know they existed” and although “We do not see them erupt, yet more than half of the Earth’s crust can be attributed to their dramatic explosions” and “In fact, the mid-ocean ridges form the largest volcanic systems on Earth. But as they are largely hidden from sight, they have long remained elusive.”
In July 2017, the BBC offered an interesting article on the potential ongoing threat from supervolcanoes around our globe(p) and the inevitability of a future eruption.
Auguste Nicaise, (1828-1900) was a French archaeologist who, in a public lecture entitled Les Terres disparues: L’Atlantide, Théra, Krakatoa delivered in Paris in 1885, is usually cited as linking Atlantis with the explosion of Thera. However, in that same address, he clearly expressed the view that the Azores, Madeira and others are the mountain peaks of submerged Atlantis.
Nicaise, merely mentioned Thera as an example of a civilisation destroyed by a natural catastrophe. He went on to describe the effects of the eruption on Krakatoa just two years earlier.
The text of the lecture, in French, is now available on the Internet(a).
The Minoan Hypothesis proposes an Eastern Mediterranean origin for Plato’s Atlantis centred on the island of Thera and/or Crete. The term ‘Minoan’ was coined by the renowned archaeologist Sir Arthur Evans after the mythic King Minos. (Sir Arthur was the son of another well-known British archaeologist, Sir John Evans). Evans thought that the Minoans had originated in Northern Egypt and came to Crete as refugees. However, recent genetic studies seem to indicate a European ancestry!
It is claimed(a) that Minoan influence extended as far as the Iberian Peninsula as early as 3000 BC and is reflected thereby what is now known as the Los Millares Culture. Minoan artefacts have also been found in the North Sea, but it is not certain if they were brought there by Minoans themselves or by middlemen. The German ethnologist, Hans Peter Duerr, has a paper on these discoveries on the Academia.edu website(e). He claims that the Minoans reached the British Isles as well as the Frisian Islands where he found artefacts with some Linear A inscriptions near the site of the old German trading town of Rungholt, destroyed by a flood in 1362(f).
The advanced shipbuilding techniques of the Minoans are claimed to have been unmatched for around 3,500 years until the 1950s (l).
The Hypothesis had its origin in 1872 when Louis Guillaume Figuier was the first to suggest  a link between the Theran explosion and Plato’s Atlantis. The 1883 devastating eruption of Krakatoa inspired Auguste Nicaise, in an 1885 lecture(c) in Paris, to cite the destruction of Thera as an example of a civilisation being destroyed by a natural catastrophe, but without reference to Atlantis.
The Minoan Hypothesis proposes that the 2nd millennium BC eruption(s) of Thera brought about the destruction of Atlantis. K.T. Frost and James Baikie, in 1909 and 1910 respectively, outlined a case for identifying the Minoans with the Atlanteans, decades before the extent of the massive 2nd millennium BC Theran eruption was fully appreciated by modern science. In 1917, Edwin Balch added further support to the Hypothesis .
As early as April 1909, media speculation was already linking the discoveries on Crete with Atlantis(h), despite Jowett’s highly sceptical opinion.
Supporters of a Minoan Atlantis suggest that when Plato wrote of Atlantis being greater than Libya and Asia he had mistranscribed meison (between) as meizon (greater), which arguably would make sense from an Egyptian perspective as Crete is between Libya and Asia, although it is more difficult to apply this interpretation to Thera which is further north and would be more correctly described as being between Athens and Asia. Thorwald C. Franke has now offered a more rational explanation for this disputed phrase when he pointed out [0750.173] that “for Egyptians the world of their ‘traditional’ enemies was divided in two: To the west, there were the Libyans, to the east there were the Asians. If an Egyptian scribe wanted to say, that an enemy was more dangerous than the ‘usual’ enemies, which was the case with the Sea Peoples’ invasion, then he would have most probably said, that this enemy was “more powerful than Libya and Asia put together”.
It has been ‘received wisdom’ that the Minoans were a peace-loving people, however, Dr Barry Molloy of Sheffield University has now shown that the exact opposite was true(d) and that “building on recent developments in the study of warfare in prehistoric societies, Molloy’s research reveals that war was, in fact, a defining characteristic of the Minoan society, and that warrior identity was one of the dominant expressions of male identity.”
In 1939, Spyridon Marinatos published, in Antiquity, his opinion that the eruption on Thera had led to the demise of the Minoan civilisation. However, the editors forbade him to make any reference to Atlantis. In 1951, Wilhelm Brandenstein published a Minoan Atlantis theory, echoing many of Frost’s and Marinatos’ ideas, but giving little credit to either.
However, Colin MacDonald, an archaeologist at the British School in Athens, believes that “Thira’s eruption did not directly affect Knossos. No volcanic-induced earthquake or tsunami struck the palace which, in any case, is 100 meters above sea level.” The Sept. 2019 report in Haaretz suggests it’s very possible the Minoans were taken over by another civilization and may have been attacked by the Mycenaeans, the first people to speak the Greek language and they flourished between 1650 B.C. and 1200 B.C. Archaeologists believe that the Minoan and Mycenaean civilisations gradually merged, with the Mycenaeans becoming dominant, leading to the shift in the language and writing system used in ancient Crete.
The greatest proponents of the Minoan Hypothesis were arguably A.G. Galanopoulos and Edward Bacon. Others, such as J.V. Luce and James Mavor were impressed by their arguments and even Jacques Cousteau explored the seas around Santorini, while Richard Mooney, the ‘ancient aliens’ writer, thought  that the Minoan theory offered a credible solution to the Atlantis mystery. More recently Elias Stergakos has proposed in an overpriced 68-page book , that Atlantis was an alliance of Aegean islands that included the Minoans.
Alain Moreau has expressed strong opposition to the Minoan Hypothesis in a rather caustic article(i), probably because it conflicts with his support for an Atlantic location for Atlantis. In more measured tones, Ronnie Watt has also dismissed a Minoan Atlantis, concluding that “Plato’s Atlantis happened to become like the Minoan civilisation on Theros rather than to be the Minoan civilisation on Theros.”
Further opposition to the Minoan Hypothesis came from R. Cedric Leonard, who has listed 18 objections(q) to the identification of the Minoans with Atlantis, keeping in mind that Leonard is an advocate of Atlantic location for Plato’s Island.
The hypothesis remains one of the most popular ideas with the general public, although it conflicts with many elements in Plato’s story. A few examples of which are, where were the Pillars of Heracles? How could Crete/Thera support an army of one million men? Where were the elephants? There is no evidence that Crete had walled cities such as Plato described. The Minoan ships were relatively light and did not require the huge harbours described in the Atlantis story. Plato describes the Atlanteans as invading from their western base (Tim.25b & Crit.114c); Crete/Santorini are not west of either Egypt or Athens
Gavin Menzies has now attempted to become the standard-bearer for the Minoan Hypothesis. In The Lost Empire of Atlantis , he argues for a vast Minoan Empire that spread throughout the Mediterranean and even discovered America [p.245]. He goes further and claims that they were the exploiters of the vast Michigan copper reserves, which they floated down the Mississippi for processing before exporting it to feed the needs of the Mediterranean Bronze industry. He also accepts Hans Peter Duerr’s evidence that the Minoans visited Germany, regularly [p.207].
Tassos Kafantaris has also linked the Minoans with the exploitation of the Michigan copper, in his paper, Minoan Colonies in America?(k) He claims to expand on the work of Menzies, Mariolakos and Kontaratos. Another Greek Professor, Minas Tsikritsis, also supports the idea of ancient Greek contact with America. However, I think it is more likely that the Minoans obtained their copper from Cyprus, whose name, after all, comes from the Greek word for copper.
Oliver D. Smith has charted the rise and decline in support for the Minoan Hypothesis in a 2020 paper entitled Atlantis and the Minoans(u).
Frank Joseph has criticised [0802.144] the promotion of the Minoan Hypothesis by Greek archaeologists as an expression of nationalism rather than genuine scientific enquiry. This seems to ignore the fact that Figuier was French, Frost, Baikie and Bacon were British, Luce was Irish and Mavor was American. Furthermore, as a former leading American Nazi, I find it ironic that Joseph is preaching about the shortcomings of nationalism.
While the suggestion of an American connection may seem far-fetched, it would seem mundane when compared with a serious attempt to link the Minoans with the Japanese, based on a study(o) of the possible language expressed by the Linear A script. Gretchen Leonhardt(r) also sought a solution in the East, offering a proto-Japanese origin for the script, a theory refuted by Yurii Mosenkis(s), who promotes Minoan Linear A as proto-Greek. Mosenkis has published several papers on the Academia.edu website relating to Linear A(t). However, writing was not the only cultural similarity claimed to link the Minoans and the Japanese offered by Leonhardt.
Furthermore, Crete has quite clearly not sunk beneath the waves. Henry Eichner commented, most tellingly, that if Plato’s Atlantis was a reference to Crete, why did he not just say so? After all, in regional terms, ‘it was just down the road’. The late Philip Coppens was also strongly opposed to the Minoan Hypothesis.(g)
Excavations on Thera have revealed very few bodies resulting from the 2nd millennium BC eruptions there. The understandable conclusion was that pre-eruption rumblings gave most of the inhabitants time to escape. Later, Therans founded a colony in Cyrene in North Africa, where you would expect that tales of the devastation would have been included in their folklore. However, Eumelos of Cyrene, originally a Theran, opted for the region of Malta as the remnants of Atlantis. How could he have been unaware of the famous history of his family’s homeland?
A 2008 documentary, Sinking Atlantis, looked at the demise of the Minoan civilisation(b). James Thomas has published an extensive study of the Bronze Age, with particular reference to the Sea Peoples and the Minoans(j).
In February 2020, art historian and museum educator, Roger Dell, presented an illustrated lecture on the art and religion of the Minoans titled “How the Matriarchal Minoans Began Western Civilization; And Why They Disappeared,” which offered a new dimension to our understanding of their culture(p).
More extreme is the theory of L. M. Dumizulu, who offers an Afrocentric view of the Atlantis. He claims that Thera was part of Atlantis and that the Minoans were black!(m)
In 2019, Nick Austin attempted  to add further support to the idea of Atlantis on Crete, but, in my opinion, he has failed.>The following year, Sean Welsh also tried to revive the Minoan Hypothesis in his book Apocalypse , placing the Atlantean capital on Santorini, which was destroyed when the island erupted around 1600 BC. He further claims that the ensuing tsunami led to the biblical story of the Deluge.
Evan Hadingham published a paper(v) in 2008 in which he discussed the possibility that the Minoan civilisation was wiped out by the tsunami generated by the eruption(s) of Thera. Then, seven years later he produced a second paper(w) exonerating the tsunami based on new evidence or lack of it.<

Krakatoa, the Indonesian volcano that erupted so violently in 1883, produced many recorded effects that are frequently used as yardsticks when discussing the possible consequences of similar events in the past, particularly the second millennium BC destruction of Thera, a leading contender in the Atlantis stakes. The Krakatoan eruption had a detrimental effect on global climates for some years.
However, this was not the first time that the eruption of Krakatoa had calamitous global consequences. David Keys (image below), an archaeological journalist, details the effects of an eruption of Krakatoa in 534/5 AD, in his book, Catastrophe. This book was the subject of a documentary on the UK’s Channel Four(d). A few years before his book was published Keys wrote an article entitled: Comet may have caused catastrophe on Earth(e), in which he dismissed a volcanic eruption as the cause of the 6th century crop failures, plagues, wars, social unrest and widespread deaths, yet his subsequent book advocates[p.269] a massive eruption of Krakatoa as the culprit. Around the same time, Mike Baillie was about to publish his Exodus to Arthur  in which he argued
strongly that the mid-6th century range of catastrophes were caused by a cometary impact. Five years later, Baillie co-authored, with Patrick McCafferty, another book linking comets with Irish mythology, The Celtic Gods, in which they point out that Keys’ proposed huge eruption has not been reflected in any of the various Greenland ice cores in the form of a volcanic-acid spike[0112.164]!
This debate regarding the cause of the global catastrophes in the mid-6th century would appear to be far from over. A 2015 report(f) suggests that a series of North American volcanic eruptions in 536 AD had such a detrimental effect on the climate of Europe that it contributed to the final demise of the Roman Empire. Furthermore, there is now evidence(g) that the eruption of the El Chicon volcano in Southern Mexico around 540 AD led to the disruption of the Maya civilisation. Matthew Toohey from the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, has suggested the possibility of a double event!
Early in the 19thcentury the eruption of Tambora, also in Indonesia, was even more powerful(a). However, the most violent eruption of the last two million years also took place in Indonesia 74,000 years ago, when Mt. Toba erupted with devastating consequences for the Indian sub-continent and further afield(b). The Toba caldera is now Lake Toba. A recent study suggested(c) that the Mt.Toba event led to the near extinction of humans.
The Theran eruption was equivalent to the 19th century Krakatoa event when measured according to a volcanic explosivity index (VEI), based on quantitative criteria, as discussed in Walter Friedrich’s book on Thera.*Within a decade, the explosivity figure for Thera was reassessed by Professor Floyd McCoy of the University of Hawaii, who has written and broadcast extensively on the matter of the Late Bonze Age eruption of Thera. This included a paper delivered to the 2005 Atlantis Conference. In it, he noted that “New finds of tephra – ash and pumice – both on land and on the seafloor indicate a far larger eruption than previously assumed, suggesting a volume of at least 100 km3 of tephra (bulk volume) ejected, perhaps more. Such a volume ranks the eruption on the Volcanic Explosivity Index (VEI) at 7.0, equivalent or larger than the 1815 eruption of Tambora (‘the year without a summer’), ten times larger than the eruption of Krakatau in 1883, and approximately 100 times that of Mt. St. Helens in 1980.” [629.311]*
Today, when we watch the 20th century eruption of Mt. St. Helens or the Montserrat volcanoes on our televisions, it gives no real notion of the incredible power of these events or the absolute terror that was experienced by those living close by.

A Shoal of mud is stated by Plato (Tim.25d) to mark the location of where Atlantis ‘settled’. Plato describes these shallows in the present tense, clearly implying that they were still a maritime hindrance in Plato’s day.
Three of the most popular translations clearly indicate this:
….the sea in those parts is impassable and impenetrable, because there is a shoal of mud in the way; and this was caused by the subsidence of the island.
…..the ocean at that spot has now become impassable and unsearchable, being blocked up by the shoal of mud which the island created as it settled down.”
…..the sea in that area is to this day impassible to navigation, which is hindered by mud just below the surface, the remains of the sunken island.
Since it is probable that Atlantis was destroyed around a thousand years or more before Solon’s Egyptian sojourn, to have continued as a hazard for such a period suggests a location that was little affected by currents or tides. The latter would seem to offer support for a Mediterranean Atlantis as that sea enjoys negligible tidal changes, as can be seen from the chart below. The darkest shade of blue indicates the areas of minimal tidal effect.
If Plato was correct in stating that Atlantis was submerged in a single day and that it was still close to the water’s surface in his own day, its destruction must have taken place a relatively short time before since the slowly rising sea levels would eventually have deepened the waters covering the remains of Atlantis to the point where they would not pose any danger to shipping. The triremes of Plato’s time had an estimated draught of about a metre so that the shallows must have had a depth that was less than that.
The reference to mud shoal resulting from an earthquake brings to mind the possibility of liquefaction. This perhaps what happened to the two submerged ancient cities close to modern Alexandria. Their remains lie nine metres under the surface of the Mediterranean.
Our knowledge of sea level changes over the past two and a half millennia should enable us to roughly estimate all possible locations in the Mediterranean where the depth of water of any submerged remains would have been a metre or less in the time of Plato.
The tidal map above offers two areas west of Athens and Egypt that do appear to be credible location regions, namely, (1) from the Balearic Islands, south to North Africa and (2) , a more credible straddling the Strait of Sicily. This region offers additional features, making it much more compatible with Plato’s account.
By contrast, just over a hundred miles south from that Strait, lies the Gulf of Gabés, which boasts the greatest tidal range (max 8 ft) within the Mediterranean.
The Gulf of Gabes formerly known as Syrtis Minor and the larger Gulf of Sidra to the east, previously known as Syrtis Major, were greatly feared by ancient mariners and continue to be very dangerous today because of the shifting sandbanks created by tides in the area.
There are two principal ancient texts that possibly support the gulfs of Syrtis as the location of Plato’s ‘shoal’. The first is from Apollonius of Rhodes who was a 3rd century BC librarian at Alexandria. In his Argonautica (Bk IV ii 1228-1250)(a) he unequivocally speaks of the dangerous shoals in the Gulf of Syrtis. The second source is the Acts of the Apostles (Acts 27 13-18) written three centuries later, which describes how St. Paul on his way to Rome was blown off course and feared that they would run aground on “Syrtis sands.” However, good fortune was with them and after fourteen days they landed on Malta. The Maltese claim regarding St. Paul is rivalled by that of the Croatian island of Mljet as well Argostoli on the Greek island of Cephalonia. Even more radical is the convincing evidence offered by Kenneth Humphreys to demonstrate that the Pauline story is an invention(b).
Both the Strait of Sicily and the Gulf of Gabes have been included in a number of Atlantis theories. The Strait and the Gulf were seen as part of a larger landmass that included Sicily according to Butavand, Arecchi and Sarantitis who named the Gulf of Gabes as the location of the Pillars of Heracles. Many commentators such as Frau, Rapisarda and Lilliu have designated the Strait of Sicily as the ‘Pillars’, while in the centre of the Strait we have Malta with its own Atlantis claims.
Zhirov[458.25] tried to explain away the ‘shoals’ as just pumice-stone, frequently found in large quantities after volcanic eruptions. However, Plato records an earthquake not an eruption and Zhirov did not explain how the pumice-stone was still a hazard many hundreds of years after the event. Although pumice can float for years, it will eventually sink(c). It was reported that pumice rafts associated with the 1883 eruption of Krakatoa were found floating up to 20 years after that event. Zhirov’s theory does not hold water (no pun intended) apart from which, Atlantis was destroyed as a result of an earthquake. not a volcanic eruption and I think that the shoals described by Plato were more likely to have been created by liquefaction and could not have endured for centuries.
>Nevertheless, a lengthy 2020 paper(d) by Ulrich Johann offers additional information about pumice and in a surprising conclusion proposes that it was pumice rafts that inspired Plato’s reference to shoals!<
