On June 3, 2024 at 23:33 UTC, a magnitude 3.8 shallow crustal earthquake struck 165 km SW of Nikolski, Alaska, at a depth of 35.0 km and coordinates 52.0837°, -170.8584°.

Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
