2022-11-03 18:57:21 UTC (2022-11-03) · approx. 3:57 AM UTC+9 local
On November 3, 2022 at 18:57 UTC, a magnitude 4.0 shallow crustal earthquake struck 6 km ESE of Kamogawa, Japan, at a depth of 36.9 km and coordinates 35.0847°, 140.1750°.
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.
