On March 11, 2026 at 20:05 UTC, a magnitude 4.4 intermediate depth earthquake struck in the Volcano Islands, Japan region, at a depth of 177.2 km and coordinates 24.5819°, 141.4855°.
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.
