On July 14, 2020 at 20:48 UTC, a magnitude 4.3 intermediate depth earthquake struck 7 km SE of Takahagi, Japan, at a depth of 93.9 km and coordinates 36.6684°, 140.7725°.
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.
