2022-11-26 21:15:45 UTC (2022-11-26) · approx. 10:15 AM UTC-11 local
On November 26, 2022 at 21:15 UTC, a magnitude 3.8 intermediate depth earthquake struck 72 km N of Nikolski, Alaska, at a depth of 240.4 km and coordinates 53.5885°, -168.9707°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
