2022-07-01 20:16:51 UTC (2022-07-01) · approx. 8:16 AM UTC-12 local
On July 1, 2022 at 20:16 UTC, a magnitude 3.0 intermediate depth earthquake struck near Andreanof Islands, Aleutian Islands, Alaska, at a depth of 192.6 km and coordinates 52.6320°, -176.1085°.
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.
