On September 4, 2026 at 19:31 UTC, a magnitude 4.2 shallow crustal earthquake struck 3 km ENE of Luzzi, Italy, at a depth of 8.8 km and coordinates 39.4652°, 16.3207°.
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.
