2022-01-14 21:27:45 UTC (2022-01-14) · approx. 10:27 AM UTC-11 local
On January 14, 2022 at 21:27 UTC, a magnitude 3.0 shallow crustal earthquake struck 69 km NW of Ambler, Alaska, at a depth of 2.0 km and coordinates 67.5489°, -158.9226°.
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.
