Earthquakes in Italy — October 2025
3 earthquakes were recorded in Italy during October 2025, an average of 0.1 per day.
2 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 10 km.
The month's largest event in Italy was a magnitude 4.9 earthquake near Ponte Sasso, Italy on 06 October 2025 at 10:13 UTC. A magnitude 4.9 earthquake radiates roughly 338 tons of TNT equivalent in seismic energy.
That is close to the Italy monthly average of 3 events over the period we cover, and up from the 1 recorded the previous month.
100% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 0% deep-focus (over 300 km). Almost everything here is crustal. That is characteristic of transform faulting or continental deformation rather than subduction — and it means shaking at the surface is strong for the magnitudes involved.
By band, the catalogue holds 1 in the magnitude 3 range, 2 in the magnitude 4 range.
The month's largest events were M4.9 near Ponte Sasso, Italy on 06 October at 10 km; M4.0 near Petruro Irpino, Italy on 24 October at 10 km; M3.0 near Rovescala, Italy on 03 October at 10 km.
That is 11% above the 3 events Italy averages per month across the 17 months on record.
