On December 23, 2020 at 20:02 UTC, a magnitude 4.3 shallow crustal earthquake struck 4 km NNE of Kamárai, Greece, at a depth of 16.7 km and coordinates 38.3397°, 22.0111°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
