2025-01-12 22:38:03 UTC (2025-01-12) · approx. 12:38 PM UTC-10 local
On January 12, 2025 at 22:38 UTC, a magnitude 3.0 intermediate depth earthquake struck 51 km WNW of Nikiski, Alaska, at a depth of 109.3 km and coordinates 60.8637°, -152.1723°.
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.
