On January 29, 2025 at 19:53 UTC, a magnitude 4.0 shallow crustal earthquake struck 66 km S of Koróni, Greece, at a depth of 41.2 km and coordinates 36.1942°, 22.0194°.
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.
