On July 27, 2024 at 20:14 UTC, a magnitude 4.3 intermediate depth earthquake struck 19 km NW of Sarabetsu, Japan, at a depth of 107.3 km and coordinates 42.7766°, 143.0088°.

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.
