On January 1, 2024 at 18:07 UTC, a magnitude 3.4 shallow crustal earthquake struck 78 km SSW of Kaktovik, Alaska, at a depth of 5.5 km and coordinates 69.4568°, -144.1662°.

Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
