2026-03-23 20:21:58 UTC (2026-03-23) · approx. 10:21 AM UTC-10 local
On March 23, 2026 at 20:21 UTC, a magnitude 3.0 intermediate depth earthquake struck 63 km W of Anchor Point, Alaska, at a depth of 98.9 km and coordinates 59.7240°, -152.9480°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
