On February 2, 2026 at 23:46 UTC, a magnitude 3.3 shallow crustal earthquake struck 68 km ESE of Sand Point, Alaska, at a depth of 20.0 km and coordinates 55.0660°, -159.5360°.

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.
