On November 15, 2023 at 20:01 UTC, a magnitude 3.2 shallow crustal earthquake struck 190 km SW of Point Hope, Alaska, at a depth of 9.7 km and coordinates 67.4414°, -170.5737°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
