2024-12-02 22:47:12 UTC (2024-12-02) · approx. 7:47 AM UTC+9 local
On December 2, 2024 at 22:47 UTC, a magnitude 3.8 deep-focus earthquake struck in the Bonin Islands, Japan region, at a depth of 516.9 km and coordinates 27.9219°, 139.6231°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
