2022-07-14 22:19:14 UTC (2022-07-14) · approx. 12:19 PM UTC-10 local
On July 14, 2022 at 22:19 UTC, a magnitude 3.2 shallow crustal earthquake struck 92 km SE of Chenega, Alaska, at a depth of 13.1 km and coordinates 59.4211°, -146.9638°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
