For example: Largo San Giorgio 1, Onifai.

Onifai, on the Cedrino plain near the Orosei coast

Onifai sits almost at sea level, at about 30 metres, on the plain of the river Cedrino, in the Baronia, the strip of eastern Sardinia between the mountains around Nuoro and the Gulf of Orosei. The beaches are a short drive away, while for hospitals, secondary schools and fuller services people go to the nearby towns or to Nuoro.

The climate is mild, climate zone C, with hot summers and short winters. Homes are mainly one or two-storey village houses, often with a courtyard, and some houses in the countryside. On a plain crossed by a river, the most important check concerns water: the report reads the official flood maps for the Cedrino and its tributaries at the exact address, and measures the elevation of the ground.

Istat, the national statistics office, counted 718 residents at the end of 2023, down 3.2% on the 742 of 2011, a modest fall. The average age is 48.9, close to the provincial 48.3, over-65s make up 28.4% and foreign residents 4.6%. Households average 2.11 people. Average declared income is below the provincial level.

Earthquakes are not a particular concern: all 53 municipalities in the province of Nuoro are in seismic zone 4, and the expected ground acceleration in Onifai is about 0.050 g.

The Revenue Agency (Agenzia delle Entrate) publishes the municipality's cadastral maps: the report starts from the address and reaches the land parcel and building.

Key points

  • Lowland village on the Cedrino, a short drive from the sea.

Overview

Onifai is a municipality in the province of Nuoro, in Sardegna. At the end of 2023 it had 718 residents, ranked 41 of 53 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Onifai 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.

Landslide and flood hazard changes from one street to the next even within Onifai: the report checks the address against the ISPRA maps.

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.
