Felt by 5 people across nearby locations.
On July 31, 2026 at 17:46 UTC, a magnitude 4.5 shallow crustal earthquake struck 3 km NNW of Torretta-Scalzapecora, Italy, at a depth of 9.2 km and coordinates 40.9385°, 14.1149°. This earthquake was detected by 63 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 314, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 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.
