2026-07-15 09:46:12 UTC (31 min ago) · approx. 11:46 PM UTC-10 local
On July 15, 2026 at 09:46 UTC, a magnitude 3.4 shallow crustal earthquake struck 6 km SW of Volcano, Hawaii, at a depth of 1.6 km and coordinates 19.3958°, -155.2765°.
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.
