M3.0 Earthquake 116 km ESE of Akutan, Alaska — November 22, 2022
2022-11-22 18:16:04 UTC (2022-11-22) · approx. 7:16 AM UTC-11 local
On November 22, 2022 at 18:16 UTC, a magnitude 3.0 shallow crustal earthquake struck 116 km ESE of Akutan, Alaska, at a depth of 35.0 km and coordinates 53.7764°, -164.1154°.
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.
