M4.1 Earthquake 93 km SSE of Sand Point, Alaska — August 26, 2026
2026-08-26 10:58:09 UTC (3 hours ago) · approx. 11:58 PM UTC-11 local
On August 26, 2026 at 10:58 UTC, a magnitude 4.1 shallow crustal earthquake struck 93 km SSE of Sand Point, Alaska, at a depth of 35.6 km and coordinates 54.5458°, -159.9993°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
