On April 6, 2025 at 18:44 UTC, a magnitude 4.4 shallow crustal earthquake struck 10 km WNW of Kalávryta, Greece, at a depth of 12.7 km and coordinates 38.0684°, 21.9988°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
