On July 10, 2026 at 12:12 UTC, a magnitude 2.5 shallow crustal earthquake struck 16 km SSW of Honaunau-Napoopoo, Hawaii, at a depth of 15.6 km and coordinates 19.3293°, -155.9447°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 97.4 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 34 m — a useful intuition for the size of the slip patch on the fault.
