Remember that huge tidal wave cresting over lower Manhattan in the 1998 asteroid-disaster movie "Deep Impact"?
Well, it really may have happened, but long before any skyscrapers were built — around 300 B.C., in fact.
Researchers from Columbia, Harvard and Vanderbilt universities first presented the hypothesis at a geologists' conference in December, and spoke more recently to the BBC.
Vanderbilt's Stephen Goodbred explained that an unusual eight-inch-thick layer of sea sand and gravel 2,300 years old lies along the shorelines and riverbanks of the entire New York metropolitan area.
Such a formation, containing chunks of rock as big as a fist, could only have been caused by a massive influx of sea water far inland — basically, a tsunami.

It will happen again when one of the Canary Islands' volcanoes erupts shattering the entire western side of Cumbre Vieja. The initial wave may tower over 1,000 feet and still maintain a 150 foot height upon crashing into the United States' East coast; affecting Boston to the Florida Keys, it is only a matter of time. Part of the island has caused a huge landslide and consequent tsunami before but I forget the time period.
