2026-03-02 22:15:39 UTC (2026-03-02) · approx. 12:15 PM UTC-10 local
On March 2, 2026 at 22:15 UTC, a magnitude 3.0 intermediate depth earthquake struck 58 km WSW of Nanwalek, Alaska, at a depth of 71.3 km and coordinates 59.1780°, -152.8870°.
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.
