On May 24, 2026 at 00:25 UTC, a magnitude 4.4 shallow crustal earthquake struck in the Bonin Islands, Japan region, at a depth of 18.0 km and coordinates 27.3645°, 142.9854°.
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.
