On June 12, 2024 at 20:05 UTC, a magnitude 4.3 shallow crustal earthquake struck 5 km N of Náfpaktos, Greece, at a depth of 11.4 km and coordinates 38.4448°, 21.8271°.

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.
