On July 30, 2024 at 17:52 UTC, a magnitude 4.1 deep-focus earthquake struck in the Bonin Islands, Japan region, at a depth of 515.8 km and coordinates 28.1068°, 139.2540°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
