“We know that relatively minor sea-level rises could set off major ice-sheet breakups, and it has been suggested by Stephen Oppenheimer that the tremendous earthquakes caused by isostatic rebalancing at the end of the Ice Age could have stirred up 'mountain-topping superwaves' in the northern regions of the Atlantic and Pacific Oceans. Other than Oppenheimer's own investigations, however, my impression is that while many brilliant individual scientists have studied individual post-glacial phenomena in great depth, very little has yet been done to investigate all these phenomena together as part of a complex system or to consider the effects on the earth and its human population of multiple, interacting cataclysms -- floods, lands subsiding into the sea, earthquakes, volcanic eruptions -- all occurring at the same time.” EarthquakesDeep Human HistoryCataclysmIce SheetsVolcanismSea Level RisesSuperwaves Book:Underworld: The Mysterious Origins of Civilization Source: Underworld: The Mysterious Origins of Civilization
