2026-07-23 22:55:57 UTC (2 hours ago) · approx. 11:55 PM UTC+1 local
On July 23, 2026 at 22:55 UTC, a magnitude 4.7 intermediate depth earthquake struck 56 km NW of Santa Domenica, Italy, at a depth of 243.1 km and coordinates 39.0003°, 15.3717°. This earthquake was detected by 96 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — 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.
