2021-11-26 21:57:03 UTC (2021-11-26) · approx. 11:57 AM UTC-10 local
On November 26, 2021 at 21:57 UTC, a magnitude 3.0 intermediate depth earthquake struck 44 km WNW of Anchor Point, Alaska, at a depth of 93.5 km and coordinates 59.9524°, -152.5378°.
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.
