2025-05-06 20:58:38 UTC (2025-05-06) · approx. 9:58 AM UTC-11 local
On May 6, 2025 at 20:58 UTC, a magnitude 3.0 shallow crustal earthquake struck 30 km ESE of Nikolski, Alaska, at a depth of 56.8 km and coordinates 52.8638°, -168.4186°.
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.
