AND IT COULD HAPPEN AGAIN: Ancient tsunami ‘hit New York’. “A huge wave crashed into the New York City region 2,300 years ago, dumping sediment and shells across Long Island and New Jersey and casting wood debris far up the Hudson River. . . . Today, a wave of the proposed size would leave Wall Street and the Long Island Expressway awash with salt water. . . . The 1929 Grand Banks tsunami, in Newfoundland, which killed more than two-dozen people and snapped many transatlantic cables, was set in motion by a submarine landslide set off by an earthquake. Dr Goodbred imagines that the New York wave was on the Grand Banks scale – three to four meters high and big enough to leap over the barrier islands; but that it did not reach the magnitude of the 2004 Sumatran tsunami.”
