On February 15, 2023 at 16:25 UTC, a magnitude 2.2 shallow crustal earthquake struck 14 km ESE of P?hala, Hawaii, at a depth of 27.5 km and coordinates 19.1710°, -155.3433°.

Physical scale: An earthquake of magnitude 2.2 releases seismic energy equivalent to roughly 31.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 20 m — a useful intuition for the size of the slip patch on the fault.
