Dr. Dallas Abbott is a geophysicist at the Lamont-Doherty Earth Observatory at Columbia University - one of the most prestigious geophysical research institutions in the world. For more than two decades, working largely outside the mainstream conversation around Holocene impacts, she has been building a case that a cosmic object struck the southern Indian Ocean within the last 12,000 years and sent a megatsunami across the hemisphere.The physical evidence she identified begins in Madagascar. Sand deposits were found at the top of a fault scarp - meaning the wave that carried them had to be at least 60 metres high to push material to an elevation of 180 metres above sea level. Abbott is direct about what that implies. No ordinary terrestrial process produces a 60-metre wave. The proposed source is a submarine crater candidate she calls Burkle Crater, situated in the southern Indian Ocean at a position her wave modelling confirms could have generated large waves reaching both Madagascar and Australia simultaneously.More recently, her team recovered a 2.8-metre ocean core from 1,000 kilometres away from the crater candidate - and the entire core, except for the top half-millimetre, consists of what she identifies as an impact tsunami layer, filled with impact glass displaying the flow textures characteristic of material that was simultaneously molten and airborne. Abbott now considers Burkle Crater a serious candidate for the Younger Dryas impact, pending geochronology results she was awaiting at the time of this recording.Learn more more on Cosmic Impacts below:https://cosmictusk.com/england-and-carolina-hit-by-tsunami-in-1014-ad/Wally on the Younger Dryas Event:https://cosmictusk.com/wally-broecker-says-a-cosmic-impact-caused-the-younger-dryas/www.cosmicsummit.live
