On April 25, 2026 at 11:43 UTC, a magnitude 4.0 intermediate depth earthquake struck 42 km WSW of Cittadella del Capo, Italy, at a depth of 272.2 km and coordinates 39.4229°, 15.4164°.

Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
