On June 5, 2026 at 02:38 UTC, a magnitude 3.3 shallow crustal earthquake struck 15 km NW of Eureka Roadhouse, Alaska, at a depth of 0.8 km and coordinates 62.0150°, -147.4070°.

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.
