Felt by 21 people across nearby locations.
On February 9, 2022 at 18:55 UTC, a magnitude 4.2 shallow crustal earthquake struck 2 km SSW of Campagnola Emilia, Italy, at a depth of 10.0 km and coordinates 44.8177°, 10.7571°.
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.
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.
