On February 9, 2022 at 20:00 UTC, a magnitude 4.6 shallow crustal earthquake struck 1 km N of Correggio, Italy, at a depth of 10.0 km and coordinates 44.7809°, 10.7829°.

Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in Italy, a region characterized by the Apennine extensional belt and Calabrian subduction zone, where Africa-Eurasia convergence produces complex faulting. View all earthquakes in Italy.
