Corchiano, tuff ravines in the Agro Falisco

Corchiano is built on tuff, the soft volcanic stone of northern Lazio, on a narrow spur between deep ravines cut by streams. It lies in the Agro Falisco, the part of the Tuscia area between Civita Castellana and the Cimini hills. The ravines around the village are protected as a natural monument, and in the woods you can still find stretches of the Roman Via Amerina and tombs carved into the rock by the Falisci, a pre-Roman people. Hazelnut orchards dominate the fields.

For buyers, tuff is where it all starts. Houses in the centre stand directly on the rock, often with cellars dug beneath, and the edge of the ravines needs close attention because tuff walls can slip or collapse. Outside the old centre there are newer detached and country houses. Rome and Viterbo can be reached by car via Civita Castellana. Overture Maps data record 3 school sites, 1 pharmacy and 19 bars and restaurants.

Istat, the national statistics office, counted 3,550 residents in 2023, down 5.1% on 2011. The average age is 46.1, below the provincial 47.5, and over-65s make up 23.4%. The share of foreign residents is high, at 10.8%. Average declared incomes are below the provincial level.

The province of Viterbo has municipalities in seismic zones 2 and 3, as classified by the Civil Protection Department (the national emergency agency). Corchiano is in zone 3, like 19 other municipalities, with an expected acceleration of about 0.113 g. Tuff is easy to work but soaks up water: in older houses, damp, cellars and walls set against the ground matter.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps and the report traces the plot from the address. Rock falls and landslides along the ravines and flooding on the stream beds are hazards to check at the exact spot.

Key points

Earthquakes

For Italy's Civil Protection Department, Corchiano is in seismic zone 3, a zone where strong earthquakes are possible but rare. The region uses a finer breakdown: here the classification is 3A. Only 20 of 60 municipalities in the province are in zone 3.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.113 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 25 inhabited census areas in Corchiano. Half of the residents live in areas scoring 66 or more.
