Onanì, an inland village near Bitti

Onanì is a small village in inland Sardinia, in the province of Nuoro, in the Bitti area, on an upland of pasture at around four hundred and fifty metres. It is livestock country, with dry-stone walls, oaks and roads linking villages that lie far apart. Nuoro is the reference town for hospitals, secondary schools and offices, and you can only get there by car.

Houses are mostly village homes in stone or block, on one or two floors, some needing renovation. Buyers should assess the roof, damp, wiring and plumbing, and insulation: this is climate zone D, with colder winters than many expect in Sardinia. Near the streams running off the upland, the report checks the official flood maps at the exact address.

In 2023 Istat, Italy's national statistics office, counted 353 residents, 77 fewer than the 430 of 2011, a fall of 17.9%. The estimated average age of 49.1 is close to the 48.3 of the province of Nuoro, and over-65s make up 26.9%. Households average 2.18 people. Declared incomes are well below the provincial average.

Earthquakes are not a worry here: all 53 municipalities in the province of Nuoro are in seismic zone 4, the lowest on the national scale set by the Civil Protection Department, and expected ground acceleration in the built-up area is about 0.050 g. The attention goes to routine upkeep of the house.

The Revenue Agency (Agenzia delle Entrate) publishes Onanì's cadastral maps, and the report traces the address to its land parcel.

Earthquakes

For Italy's Civil Protection Department, Onanì is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 53 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.050 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.
