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. 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^[744], in which he links the Burckle Impact with the inundation described in the widely discredited Oera Linda Book. He places his megatsunami in 2193 BC, borrowing the date from the Oera Linda Book.
