Illorai, a Goceano village above the Tirso valley

Illorai belongs to the Goceano, a historical district of north-central Sardinia between the Goceano range and the Tirso valley. The village sits at about 500 metres on the slope overlooking the Tirso valley, surrounded by woods, pasture and farmland. The larger towns for services and work are some way off: people drive to Ozieri, Nuoro or Sassari depending on what they need.

The population has shrunk considerably: there were 730 residents in 2023, 23.4% fewer than in 2011 (Istat, the national statistics office). The average age is 50.8 against 48.3 in the province of Sassari, and over-65s make up 32.1% against 26.6%. Foreign residents are very few, 0.7%. Declared incomes are below the provincial average.

Homes are mostly village houses in stone or block, often with a courtyard, some renovated and others needing work. For buyers, the state of the roof, damp in the walls and the efficiency of the heating matter: this is climate zone D, but at this height winters are colder than on the coast. The village streets slope, and the report reads gradient and the official landslide maps for each address.

On earthquakes the picture is calm. All 66 municipalities in the province are in seismic zone 4, the lowest class, and the expected ground acceleration in Illorai is about 0.050 g. In older buildings, maintenance and insulation matter more.

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

Key points

Overview

Illorai is a municipality in the province of Sassari, in Sardegna. At the end of 2023 it had 730 residents, ranked 44 of 66 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Illorai is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 66 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.
