On August 23, 2022 at 22:58 UTC, a magnitude 3.0 shallow crustal earthquake struck 21 km SSE of Waimea, Hawaii, at a depth of 24.2 km and coordinates 19.8610°, -155.5662°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
