M3.8 Earthquake 209 km S of False Pass, Alaska — March 2, 2026
2026-03-02 19:12:13 UTC (2026-03-02) · approx. 8:12 AM UTC-11 local
On March 2, 2026 at 19:12 UTC, a magnitude 3.8 shallow crustal earthquake struck 209 km S of False Pass, Alaska, at a depth of 36.2 km and coordinates 52.9900°, -162.9630°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
