Causes of the Earthquake

New England’s seismic activity is primarily due to intraplate stresses within the North American Plate. Unlike regions near tectonic plate boundaries, these earthquakes result from internal forces causing faults to slip. While the exact fault responsible for this event is undetermined, such occurrences, though uncommon, are not unprecedented in the area.
