On July 24, 2024 at 21:34 UTC, a magnitude 3.1 shallow crustal earthquake struck 7 km S of Volcano, Hawaii, at a depth of 0.1 km and coordinates 19.3792°, -155.2427°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 722 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 86 m — a useful intuition for the size of the slip patch on the fault.
