M3.0 Earthquake 143 km SSE of False Pass, Alaska — November 20, 2024
2024-11-20 23:10:56 UTC (2024-11-20) · approx. 12:10 PM UTC-11 local
On November 20, 2024 at 23:10 UTC, a magnitude 3.0 shallow crustal earthquake struck 143 km SSE of False Pass, Alaska, at a depth of 10.0 km and coordinates 53.6025°, -162.8774°.
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.
