On April 17, 2025 at 22:17 UTC, a magnitude 3.0 shallow crustal earthquake struck 38 km WSW of Sand Point, Alaska, at a depth of 67.5 km and coordinates 55.2086°, -161.0610°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
