2022-08-10 18:09:24 UTC (2022-08-10) · approx. 7:09 AM UTC-11 local
On August 10, 2022 at 18:09 UTC, a magnitude 3.4 shallow crustal earthquake struck 75 km E of Nikolski, Alaska, at a depth of 35.0 km and coordinates 52.8849°, -167.7447°.
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.
