On April 12, 2025 at 23:38 UTC, a magnitude 4.1 shallow crustal earthquake struck 20 km WSW of Lefkáda, Greece, at a depth of 10.0 km and coordinates 38.7813°, 20.4740°.
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.
