On November 15, 2024 at 18:51 UTC, a magnitude 4.4 deep-focus earthquake struck in the Bonin Islands, Japan region, at a depth of 529.1 km and coordinates 27.8364°, 139.4118°.

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.
