On July 21, 2026 at 03:06 UTC, a magnitude 3.0 shallow crustal earthquake struck 3 km SSW of Pāhala, Hawaii, at a depth of 31.5 km and coordinates 19.1720°, -155.4853°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 445 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 69 m — a useful intuition for the size of the slip patch on the fault.
