M3.5 Earthquake 50 km W of Anchor Point, Alaska — November 22, 2024
2024-11-22 21:52:57 UTC (2024-11-22) · approx. 11:52 AM UTC-10 local
On November 22, 2024 at 21:52 UTC, a magnitude 3.5 intermediate depth earthquake struck 50 km W of Anchor Point, Alaska, at a depth of 86.8 km and coordinates 59.7255°, -152.7156°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
