The Burckle Abyssal Impact Crater is named after Dr. Lloyd Burckle of Columbia University in the United States. It is a 30km wide underwater crater around 1500km south-east of Madagascar, considered by some to have been the result of a cometary impact less than 6,000 years ago. Wikipedia describes it as a hypothetical underwater feature(a)founded on a study of chevron dune The chevron-tsunami linkage is disputed by University of Washington geologist and tsunami expert Jody Bourgeois(e), among others.
A paper presented to the 2005 Atlantis Conference explored the possibility that this impact resulted in one of the inundations referred to by Plato that preceded the flood of Deucalion. Acceptance of this view would add weight to the claim that Plato’s Atlantis story contains matters that are historically factual. However, if Plato’s floods were localised in the Mediterranean, it is difficult to understand how an impact in the middle of the Indian Ocean could have caused them.
In 2010 a South African writer, Alewyn J. Raubenheimer, published Survivors of the Great Tsunami, in which he linked the Burckle Impact with the inundation described in the widely discredited Oera Linda Book. He placed his megatsunami in 2193 BC, borrowing the date from the Oera Linda Book. Raubenheimer’s defence of the OLB has generated widespread support(c)(d).
*Raubenheimer’s dating of the megatsunami is rather different to that of Kevin Curran in his Fall of a Thousand Suns, in which he offers more compelling evidence for a date of 3067 BC. Readers may find it useful to read Curran’s book along with the work of Dallas Abbott who has dated the Burckle Event to 2870 BC and sees the impact as just one from of a fragmented comet(f).*
