On January 22, 2024 at 23:45 UTC, a magnitude 4.2 shallow crustal earthquake struck 5 km SSE of Gojō, Japan, at a depth of 67.4 km and coordinates 34.3042°, 135.7257°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
