Villasalto, Gerrei hills and old mines

The land around Villasalto, in the Gerrei area of Sardinia, still bears the marks of mining: the best known site is Su Suergiu, where antimony was extracted, now closed. The village stands at around 500 metres among hills and uplands covered with scrub and pasture, far from the coast and the big towns. For a hospital, secondary schools and most jobs, people drive towards Cagliari and the larger towns of the province.

The population is elderly and shrinking. At the end of 2023 there were 938 residents, 16.8% fewer than in 2011; the average age is 53.4, against 48.1 in the province, and over-65s make up 37.6% of residents. Households have 2.02 people on average.

Most homes for sale are traditional stone houses, often with a courtyard, alongside more recent buildings. For a buyer it matters to know the type of wall, because it determines what work is possible and what it costs, and to check the roof and damp. The climate zone is D: winters are not harsh, but the nights are cold.

Earthquakes are a minor issue here. All 70 municipalities in the province are in seismic zone 4, the lowest class set by the Civil Protection Department, and the expected ground acceleration in the built-up area is 0.050 g.

The Revenue Agency (Agenzia delle Entrate) land registry covers Villasalto. The report works back from the address to the parcel and gives landslide and flood hazard, slope and the real distance to services, worth measuring carefully in a village far from the main towns.

Key points

Overview

Villasalto is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 938 residents, ranked 57 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Villasalto is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 70 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.
