Study: Boston, New England at Greatest Tsunami Risk in US

Nuclear power plants on U.S. East Coast from New Jersey northward

An increase in seismic activity in the North Atlantic suggests that New England is most at risk of suffering the effects of a tsunami in the near future [...]

Over the past year there have been 12 small earthquakes at the edge of the continental shelf – about 170 miles east of Boston – with the most powerful being a magnitude 4 quake that occurred April 12, 2012, says John Ebel, of Boston College’s Weston Observatory [...]

“when we have more frequent small earthquake activity, there’s a greater chance of having a larger one in the future.”

In 1929, a magnitude 7.2 earthquake off the coast of Newfoundland caused a tsunami to hit Canada, killing 27 people, destroying thousands of homes and cutting transatlantic communication lines.

[...] the coasts between Nova Scotia and New Jersey are at highest risk for a tsunami. [...]

More from Ebel

I’m drawing an analogy from the 1929 area to this area that reaches to Boston. Geologically, it looks the same. The earthquakes are occurring right at the edge of the continental shelf.
