On July 20, 2024 at 21:45 UTC, a magnitude 2.5 shallow crustal earthquake struck 6 km S of Volcano, Hawaii, at a depth of 1.9 km and coordinates 19.3845°, -155.2403°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 81.9 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 31 m — a useful intuition for the size of the slip patch on the fault.
