2026-08-28 23:28:36 UTC (36 min ago) · approx. 12:28 PM UTC-11 local
On August 28, 2026 at 23:28 UTC, a magnitude 3.4 shallow crustal earthquake struck 215 km SSE of False Pass, Alaska, at a depth of 18.9 km and coordinates 53.1130°, -161.9870°.
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.
