On September 26, 2025 at 18:06 UTC, a magnitude 2.5 shallow crustal earthquake struck 9 km S of Kukuihaele, Hawaii, at a depth of 31.2 km and coordinates 20.0345°, -155.5567°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 76.5 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.
