2026-10-11 17:05:53 UTC (21 hours ago) · approx. 3:05 AM UTC+10 local
On October 11, 2026 at 17:05 UTC, a magnitude 4.4 shallow crustal earthquake struck in the Volcano Islands, Japan region, at a depth of 10.0 km and coordinates 22.0334°, 143.5141°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
