On October 31, 2026 at 01:01 UTC, a magnitude 4.2 shallow crustal earthquake struck 35 km SSE of Sykiá, Greece, at a depth of 10.0 km and coordinates 39.7672°, 24.1487°.
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.
