On January 1, 2022 at 15:37 UTC, a magnitude 4.4 intermediate depth earthquake struck 214 km SSE of Tateyama, Japan, at a depth of 98.8 km and coordinates 33.1118°, 140.4678°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
