On March 25, 2023 at 20:56 UTC, a magnitude 4.1 shallow crustal earthquake struck 37 km SSE of Pýrgos, Greece, at a depth of 39.2 km and coordinates 34.6920°, 25.3067°.
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.
