The closest seismic structure
The town lies about 14 km from Salto Lake-Ovindoli-Barrea, one of the seismic structures mapped by INGV geologists.
Faults are mapped to build better and understand the territory: knowing them says nothing about when an earthquake will occur, which remains unpredictable. Source: DISS 3.3 (INGV, CC BY 4.0).
