M3.3 Earthquake 151 km S of False Pass, Alaska — January 2, 2025
2025-01-02 18:15:30 UTC (2025-01-02) · approx. 7:15 AM UTC-11 local
On January 2, 2025 at 18:15 UTC, a magnitude 3.3 shallow crustal earthquake struck 151 km S of False Pass, Alaska, at a depth of 35.0 km and coordinates 53.4975°, -163.5881°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
