On July 10, 2026 at 12:12 UTC, a magnitude 2.7 shallow crustal earthquake struck 17 km SW of Honaunau-Napoopoo, Hawaii, at a depth of 17.2 km and coordinates 19.3280°, -155.9575°.

Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 175 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 45 m — a useful intuition for the size of the slip patch on the fault.
