On January 26, 2024 at 19:44 UTC, a magnitude 4.3 shallow crustal earthquake struck 86 km E of Tomioka, Japan, at a depth of 32.1 km and coordinates 37.4430°, 141.9884°.
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.
