Bortigiadas, a granite village in inland Gallura

Bortigiadas is a village in inland Gallura, far from the tourist resorts of the coast, built among granite rocks at about 480 metres. Tempio Pausania is the nearest town for secondary schools, hospital and offices; for everything else people look to Olbia and Sassari, reached by car. Around the village are pastures, woods and countryside with scattered houses.

Homes are mostly stone village houses on one or two floors, plus some country houses. The climate zone is D, with winters cooler than on the coast. On sloping plots the report measures elevation and gradient and reads the official landslide and stream flood maps for the exact address.

At the end of 2023 there were 709 residents, 91 fewer than in 2011 (down 11.4%). The population is much older than the provincial one: an average age of 51.5 against 46.7, over-65s at 33.3% against 23.3%. Foreign residents make up 5.6%. Average declared income remains below the provincial average.

Earthquakes are not a particular worry: the 26 municipalities in the province are all in seismic zone 4, and in Bortigiadas the expected ground acceleration is about 0.050 g. In stone houses the roof, damp walls and the systems matter most.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for the municipality, and the report traces an address to its land parcel and building.

Overview

Bortigiadas is a municipality in the province of Gallura Nord-Est Sardegna, in Sardegna. At the end of 2023 it had 709 residents, among the smallest in the province (26 of 26).

Earthquakes

For Italy's Civil Protection Department, Bortigiadas is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 26 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.

Population

Compared with the 2011 census, the resident population has fallen by 11.4%. The estimated average age is 52 years, higher than the province average (47). 33% of residents are over 65 (the regional figure is 27%). Foreign residents make up 5.6% of the population. On average, a household has 2.1 members.
