2024-01-02 18:51:50 UTC (2024-01-02) · approx. 7:51 AM UTC-11 local
On January 2, 2024 at 18:51 UTC, a magnitude 3.9 shallow crustal earthquake struck 66 km S of Gambell, Alaska, at a depth of 20.3 km and coordinates 63.1789°, -171.6799°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
