Ternengo, in the hills of eastern Biellese

The area east of Biella is a belt of low, wooded hills, shaped for more than a century by the textile industry, and Ternengo is one of the small municipalities in it, at about four hundred and thirty metres. The village is a collection of houses and small clusters among woods and meadows, a short drive from Biella and Cossato.

That proximity is the strong point for buyers. Biella has a hospital, secondary schools, shops and jobs, and life in such a small village stays closely tied to the town. There are hardly any services locally, and without a car you cannot get around. Homes are mostly detached houses and old rural masonry buildings; with the latter, check the roof, floors and wiring and plumbing. The climate zone is E.

According to Istat, Italy's national statistics office, there were 256 residents in 2023, 42 fewer than the 298 of 2011, a fall of 14.1%. The estimated average age is 53.2, above the 49.7 of the province of Biella, and over-65s make up 35.9% against 30.1%. Foreign residents account for 2.7%. Declared incomes are a little below the provincial average.

Earthquake risk is low. Ternengo is in seismic zone 4, the lowest on the Civil Protection Department's scale, like 50 of the 74 municipalities in the province, and expected acceleration is about 0.041 g. On the Biella hills, slope stability and drainage matter more. The report gives the slope and the official landslide maps for the address, starting from the Revenue Agency's cadastral maps.

Overview

Ternengo is a municipality in the province of Biella, in Piemonte. At the end of 2023 it had 256 residents, among the smallest in the province (66 of 74).

Earthquakes

For Italy's Civil Protection Department, Ternengo is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (50 of 74) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.041 g, a low 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 14.1%. The estimated average age is 53 years, higher than the province average (50). 36% of residents are over 65 (the regional figure is 27%). Foreign residents make up 2.7% of the population. On average, a household has 2.0 members.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection.
