Bidonì, on the hills running down to Lake Omodeo

The hills of Bidonì slope down to Lake Omodeo, the reservoir formed by the dam on the river Tirso in the middle of Sardinia. The village is small, at around two hundred and fifty metres, with low houses and streets that follow the slope, surrounded by pasture, scrub and patches of woodland. For schools, healthcare and shopping people go to the larger towns in the province of Oristano, and the provincial capital is within driving distance.

Houses for sale are usually old family homes. Before buying, look carefully at the roof, damp, wiring and drains, which often need redoing in older houses. The report adds distances to schools, pharmacies and shops measured from the address.

In 2023 Istat, the national statistics office, recorded 122 residents, against 147 in 2011: a fall of 17.0%. Over-65s make up 35.2%, more than the provincial 29.5%, and the estimated average age is 52.3. Households have 1.94 people on average. Declared incomes are well below the provincial average.

Earthquake hazard is low everywhere in Sardinia: all 87 municipalities in the province are in zone 4 of the Civil Protection Department's scale, and the expected ground acceleration in Bidonì is about 0.050 g. The climate is mild (climate zone C) and heating costs stay modest.

On the slopes towards the lake and along the streams, landslide and flood hazard changes from one spot to another, and the report reads it from the official maps for each house. Revenue Agency (Agenzia delle Entrate) cadastral maps are available here too.

Earthquakes

For Italy's Civil Protection Department, Bidonì is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 87 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.
