On July 14, 2024 at 18:37 UTC, a magnitude 2.1 shallow crustal earthquake struck 14 km NNE of Kalaoa, Hawaii, at a depth of 39.3 km and coordinates 19.8463°, -155.9253°.

Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 22.0 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 17 m — a useful intuition for the size of the slip patch on the fault.
