On February 9, 2025 at 20:55 UTC, a magnitude 4.3 shallow crustal earthquake struck 116 km SW of Kýthira, Greece, at a depth of 46.9 km and coordinates 35.3102°, 22.2139°.0

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.
