2026-01-10 18:19:52 UTC (2026-01-10) · approx. 8:19 AM UTC-10 local
On January 10, 2026 at 18:19 UTC, a magnitude 3.4 shallow crustal earthquake struck 216 km SSW of Akhiok, Alaska, at a depth of 9.6 km and coordinates 55.0560°, -155.0200°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
