M3.0 Earthquake 38 km SSE of False Pass, Alaska — January 30, 2022
2022-01-30 21:40:09 UTC (2022-01-30) · approx. 10:40 AM UTC-11 local
On January 30, 2022 at 21:40 UTC, a magnitude 3.0 shallow crustal earthquake struck 38 km SSE of False Pass, Alaska, at a depth of 10.0 km and coordinates 54.5195°, -163.2507°.
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.
