2022-12-22 21:16:54 UTC (2022-12-22) · approx. 11:16 AM UTC-10 local
On December 22, 2022 at 21:16 UTC, a magnitude 3.2 shallow crustal earthquake struck 7 km WSW of Anchor Point, Alaska, at a depth of 57.6 km and coordinates 59.7386°, -151.9514°.
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.
