On August 10, 2026 at 06:22 UTC, a magnitude 3.4 shallow crustal earthquake struck 43 km ESE of Naalehu, Hawaii, at a depth of 35.0 km and coordinates 18.8608°, -155.2318°.

Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
