2026-08-10 06:21:43 UTC (20 min ago) · approx. 8:21 PM UTC-10 local
On August 10, 2026 at 06:21 UTC, a magnitude 3.1 shallow crustal earthquake struck 16 km SE of Pāhala, Hawaii, at a depth of 33.4 km and coordinates 19.0812°, -155.3832°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 722 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 86 m — a useful intuition for the size of the slip patch on the fault.
