On November 11, 2022 at 23:02 UTC, a magnitude 2.3 shallow crustal earthquake struck 22 km E of Susitna North, Alaska, at a depth of 36.0 km and coordinates 62.1914°, -149.4270°.

Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 42.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.
