On March 16, 2022 at 22:24 UTC, a magnitude 4.0 intermediate depth earthquake struck 104 km NNE of Hirara, Japan, at a depth of 108.4 km and coordinates 25.7332°, 125.5063°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
