2022-10-10 23:24:55 UTC (2022-10-10) · approx. 12:24 PM UTC-11 local
On October 10, 2022 at 23:24 UTC, a magnitude 3.4 intermediate depth earthquake struck 49 km SW of Nelson Lagoon, Alaska, at a depth of 160.9 km and coordinates 55.6530°, -161.6996°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
