2024-12-16 20:58:49 UTC (2024-12-16) · approx. 9:58 AM UTC-11 local
On December 16, 2024 at 20:58 UTC, a magnitude 3.1 shallow crustal earthquake struck 192 km SSE of Nikolski, Alaska, at a depth of 10.0 km and coordinates 51.3819°, -167.6404°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
