On March 4, 2022 at 22:50 UTC, a magnitude 2.2 shallow crustal earthquake struck 2 km SSE of Erving, Massachusetts, at a depth of 2.5 km and coordinates 42.5807°, -72.3889°.
Physical scale: An earthquake of magnitude 2.2 releases seismic energy equivalent to roughly 30.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 20 m — a useful intuition for the size of the slip patch on the fault.
