2026-08-05 00:05:51 UTC (4 hours ago) · approx. 1:05 PM UTC-11 local
On August 5, 2026 at 00:05 UTC, a magnitude 3.3 shallow crustal earthquake struck 45 km E of Savoonga, Alaska, at a depth of 10.0 km and coordinates 63.7450°, -169.5710°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
