2025-01-28 18:16:37 UTC (2025-01-28) · approx. 7:16 AM UTC-11 local
On January 28, 2025 at 18:16 UTC, a magnitude 3.4 intermediate depth earthquake struck 116 km WNW of Nikolski, Alaska, at a depth of 206.6 km and coordinates 53.2734°, -170.5046°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
