Isn't NYC on a fault and upstate NY as well?
Yes, there are faults on the immediate East Coast, and there is a fault under NYC, but it really hasn't been active, even a small (M5) quake under NYC would be devastating but the threat is somewhat debateable. New Jersey has more active faults, and there was a quite large quake in Massachusetts in 1755.
There are some good sized quakes in Upstate NY around Attica, and also in the Adirondacks, but not much to damage in the Adirondacks.
And then the St. Lawrence Valley in Canada and extreme N New York is a LOT like the New Madrid Seismic Zone; they've had some BIG BIG quakes in Canada.
