On October 26, 2024 at 17:10 UTC, a magnitude 4.1 shallow crustal earthquake struck 73 km SE of Akkeshi, Japan, at a depth of 36.3 km and coordinates 42.5625°, 145.4838°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
