On June 18, 2026 at 12:11 UTC, a magnitude 2.8 shallow crustal earthquake struck 13 km SSW of Honoka‘a, Hawaii, at a depth of 27.3 km and coordinates 19.9625°, -155.5080°.

Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 208 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 48 m — a useful intuition for the size of the slip patch on the fault.
