On May 11, 2026 at 13:06 UTC, a magnitude 4.2 shallow crustal earthquake struck 31 km WSW of Pýrgos, Greece, at a depth of 25.0 km and coordinates 37.5328°, 21.1373°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
