On February 5, 2024 at 19:21 UTC, a magnitude 4.3 intermediate depth earthquake struck 44 km ENE of Nemuro, Japan, at a depth of 94.9 km and coordinates 43.4167°, 146.1099°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
