Viddalba, in the lower Coghinas valley

Viddalba lies in Anglona, in northern Sardinia, in the lower valley of the river Coghinas, not far from the coast of the Gulf of Asinara. The village sits almost at sea level, surrounded by fields and orchards watered by the river, with the Anglona hills behind it.

That position shapes much of what a buyer needs to know. Near the Coghinas and on the flat valley floor, flooding has to be checked house by house, using the official maps that the report reads at the exact address. The beaches of the north coast are a short drive away, while Sassari, further off, is the reference for larger services. The climate is mild, zone B, with short and gentle winters, and declared incomes are below the provincial average.

In 2023 Viddalba had 1,595 residents, according to Istat, the national statistics office, down 5.8% on 2011. The average age of 48.8 is close to the provincial figure of 48.3, and foreign residents make up 4.1%.

On earthquakes, the picture is calm: all 66 municipalities in the province of Sassari are in seismic zone 4, and the expected ground acceleration here is 0.050 g. In older houses, focus on damp, the roof and the services.

The Revenue Agency's cadastral maps are published, so the report traces the land parcel from the address and measures distances to services from the house.

Key points

  • Lower Coghinas valley in Anglona, near the north coast.
  • Mild climate, zone B.
  • All 66 municipalities in the province in seismic zone 4.

Overview

Viddalba is a municipality in the province of Sassari, in Sardegna. At the end of 2023 it had 1,595 residents, ranked 27 of 66 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Viddalba 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.
