On March 11, 2025 at 12:30 UTC, a magnitude 4.1 intermediate depth earthquake struck 22 km E of Rausu, Japan, at a depth of 160.5 km and coordinates 43.9801°, 145.4666°.
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.
