On July 20, 2024 at 16:44 UTC, a magnitude 4.0 shallow crustal earthquake struck 44 km SSW of Palaióchora, Greece, at a depth of 46.9 km and coordinates 34.8673°, 23.4903°.
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.
