Picture, for a moment, a monster tsunami racing across the Atlantic at near-supersonic speed. As it nears the eastern seaboard it rises to nearly 300 feet in height and rages inland for nearly 16 miles, scouring everything in its path. New York, Boston, Miami, Washington and a multitude of other Atlantic cities are utterly devastated.... According to geologist Bill McGuire, a Benfield professor of geophysical hazards at University of College of London, it is only a matter of time before Cumbre Vieja erupts and sheds a good portion of it and its surrounding territory into the Atlantic deep.
