On July 22, 2026 at 18:51 UTC, a magnitude 3.2 shallow crustal earthquake struck 105 km SSE of Akhiok, Alaska, at a depth of 6.1 km and coordinates 56.1270°, -153.3220°.
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.
