On December 13, 2022 at 17:33 UTC, a magnitude 4.2 intermediate depth earthquake struck 1 km NNW of Aígio, Greece, at a depth of 75.8 km and coordinates 38.2628°, 22.0759°.0
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.
