On June 8, 2024 at 18:09 UTC, a magnitude 3.3 shallow crustal earthquake struck 67 km ESE of Sand Point, Alaska, at a depth of 41.2 km and coordinates 55.0397°, -159.5810°.

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.
