New York like all the continental US sits on the North American plate, which is pretty stable except at the edges like the Mid-Atlantic Ridge and the Pacific coast. There are places where very old fault systems slip from time to time. Charleston SC and Paducah KY have a much higher risk than NY. "Risk" doesn't mean much when one actually happens.

Sometimes one happens where it's hard to explain, like last year due south of Mobile AL in deep Gulf of Mexico, 3.3.
