2022-11-19 21:53:32 UTC (2022-11-19) · approx. 11:53 AM UTC-10 local
On November 19, 2022 at 21:53 UTC, a magnitude 3.0 intermediate depth earthquake struck 63 km SE of Kokhanok, Alaska, at a depth of 123.2 km and coordinates 59.0573°, -153.9395°.
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.
