On February 23, 2024 at 22:05 UTC, a magnitude 2.4 intermediate depth earthquake struck 14 km W of Healy, Alaska, at a depth of 119.5 km and coordinates 63.8316°, -149.2611°.

Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 60.0 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 27 m — a useful intuition for the size of the slip patch on the fault.
