2026-11-11 20:24:46 UTC (22 min ago) · approx. 10:24 AM UTC-10 local
On November 11, 2026 at 20:24 UTC, a magnitude 3.3 shallow crustal earthquake struck 131 km SSE of Old Harbor, Alaska, at a depth of 5.8 km and coordinates 56.1250°, -152.4430°.
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.
