On July 28, 2026 at 19:19 UTC, a magnitude 3.3 shallow crustal earthquake struck 50 km WSW of Pelican, Alaska, at a depth of 5.3 km and coordinates 57.8250°, -137.0490°.

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.
