Gonars, farmland of the Friulian lowlands near Palmanova
Fields of maize and soya split by ditches and rows of trees, a compact village around the church and small industrial areas on the edges: Gonars is a municipality in the lowlands of Friuli, west of Palmanova and about twenty kilometres south of Udine. Besides the main village it includes the hamlets of Fauglis and Ontagnano.
Its location is the main draw for people who work elsewhere. The Palmanova junction, where the A4 motorway between Venice and Trieste meets the A23 towards Udine and Austria, is a few minutes away. For hospitals, secondary schools and larger shops, people look to Udine, Palmanova and Cervignano. In the village the data counts 34 services, including 4 school sites.
The population is falling slowly. At the end of 2023 there were 4,530 residents, 5.4% fewer than at the 2011 census. The average age is 49.1, in line with the province of Udine (48.5), and over-65s make up 27.9%. Foreign residents account for 4.8%, households have 2.24 members on average and declared incomes sit just below the provincial average.
Seismic risk is lower than in the Friulian hills. Gonars is in seismic zone 3 of the Civil Protection classification, along with 43 other municipalities in the province, while further north 19 are in zone 1, the highest. Expected ground acceleration is about 0.137 g. Even so, for a house from the 1960s or 1970s it is worth asking how the structure is built.
On the plain, water is the thing to watch. The report checks the flood maps for the address and how close it is to ditches and drainage channels, details that vary from one plot to the next within the same village.

Earthquakes
For Italy's Civil Protection Department, Gonars is in seismic zone 3, a zone where strong earthquakes are possible but rare. Only 44 of 134 municipalities in the province are in zone 3.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.137 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.
Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
