I've been assuming that a devastating tsunami was unlikely along the New England coast until an old friend pointed out the 1929 Grand Banks Earthquake, 7.2, which generated a tsunami that devastated much of the Southern Newfoundland coast with waves of 2-7 metres, in some long bays the waves reached 13 metres! Here's some background info: click here for report!

Anyone want to guess how high the tsnuami wall is at the Seabrook nuclear plant in New Hampshire? Oh, they never built one...

Have a nice day!
