Tectonic Summary
This earthquake occurred in the northeastern part of New York State, an area that experiences moderate-sized but infrequent seismic activity. Although earthquakes occur on geologic faults, in the northeastern U.S. it is difficult to assign an earthquake to a particular fault because they rarely cause surface rupture.
The most recent nearby earthquake of note occurred 80 km to the southwest, a magnitude 5.1 event in 1983. The largest historic earthquake in the northeastern region of the U.S. and nearby parts of Canada had an estimated magnitude of 7. It occurred near Charlevoix, Quebec in 1663, 425 km to the northeast of this latest event.
