2026-01-13 21:57:36 UTC (2026-01-13) · approx. 10:57 AM UTC-11 local
On January 13, 2026 at 21:57 UTC, a magnitude 3.4 shallow crustal earthquake struck 56 km S of Ivanof Bay, Alaska, at a depth of 22.4 km and coordinates 55.3940°, -159.3740°.
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.
