M3.2 Earthquake 128 km W of Point Lay, Alaska — October 2, 2022
2022-10-02 20:13:07 UTC (2022-10-02) · approx. 9:13 AM UTC-11 local
On October 2, 2022 at 20:13 UTC, a magnitude 3.2 shallow crustal earthquake struck 128 km W of Point Lay, Alaska, at a depth of 11.7 km and coordinates 69.6579°, -166.3234°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
