On July 18, 2026 at 09:04 UTC, a magnitude 4.3 shallow crustal earthquake struck 25 km N of Gázi, Greece, at a depth of 18.5 km and coordinates 35.5522°, 25.0290°.

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.
