On April 10, 2023 at 22:35 UTC, a magnitude 4.1 shallow crustal earthquake struck 46 km S of Palekastro, Greece, at a depth of 43.7 km and coordinates 34.7857°, 26.3309°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
