On November 5, 2022 at 18:53 UTC, a magnitude 2.1 shallow crustal earthquake struck 5 km NNW of Nantucket, Massachusetts, at a depth of 10.9 km and coordinates 41.3298°, -70.1310°. This earthquake was detected by 27 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 86, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 21.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 17 m — a useful intuition for the size of the slip patch on the fault.
