On August 18, 2025 at 19:38 UTC, a magnitude 4.3 shallow crustal earthquake struck 10 km SSW of Anávra, Greece, at a depth of 20.0 km and coordinates 39.1080°, 22.0358°.
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.
