On September 6, 2020 at 23:49 UTC, a magnitude 4.4 shallow crustal earthquake struck 50 km SSE of Hasaki, Japan, at a depth of 40.5 km and coordinates 35.3158°, 141.0635°.
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.
