On August 5, 2026 at 14:20 UTC, a magnitude 2.8 shallow crustal earthquake struck 2 km WSW of Honoka‘a, Hawaii, at a depth of 8.2 km and coordinates 20.0682°, -155.4903°.

Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 256 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 53 m — a useful intuition for the size of the slip patch on the fault.
