On September 3, 2026 at 22:39 UTC, a magnitude 3.4 shallow crustal earthquake struck 19 km SE of Pāhala, Hawaii, at a depth of 31.9 km and coordinates 19.0660°, -155.3590°.0

Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 2.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 136 m — a useful intuition for the size of the slip patch on the fault.
