2026-08-11 09:36:41 UTC (1 hour ago) · approx. 10:36 PM UTC-11 local
On August 11, 2026 at 09:36 UTC, a magnitude 4.4 shallow crustal earthquake struck 98 km SSE of Sand Point, Alaska, at a depth of 34.4 km and coordinates 54.5029°, -159.9604°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
