2023-11-22 21:07:31 UTC (2023-11-22) · approx. 11:07 AM UTC-10 local
On November 22, 2023 at 21:07 UTC, a magnitude 3.0 intermediate depth earthquake struck 59 km W of Nanwalek, Alaska, at a depth of 85.6 km and coordinates 59.4112°, -152.9625°.
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.
