On November 1, 2024 at 21:10 UTC, a magnitude 4.2 intermediate depth earthquake struck 14 km ENE of Miyako, Japan, at a depth of 72.8 km and coordinates 39.7061°, 142.0966°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
