Bioglio, hills and hamlets near Biella

On the heights not far from Biella, the municipality of Bioglio brings together a small centre and several hamlets scattered among chestnut woods, meadows and terraces. The town hall stands at around 500 metres, and from many points the view stretches to the plain.

The Biella area is known for its wool mills and industry, and for decades people from villages like this went down every day to the factories in the valleys and in town. Today buyers come mainly for peace and space. Homes are largely stone and masonry houses in the hamlets, sometimes large, along with more recent detached houses. Narrow, steep lanes, garages that are not always there and some hamlets with awkward winter access should be weighed up before signing. For services, secondary schools and the hospital you go to Biella.

In 2023 there were 913 residents, down 7.4% on the 2011 census, according to Istat, the national statistics office. The average age is 50.8, just above the provincial figure of 49.7, and over-65s make up 30.7%, much as in the province. Households average 1.97 people and foreign residents account for 2.3%. Declared incomes are below the Biella average.

The province of Biella is split between zones 3 and 4 in the Civil Protection classification: Bioglio is in seismic zone 4 with 49 other municipalities, while 24 are in the higher hazard zone. Expected ground acceleration is 0.042 g. In a hamlet house the practical points are the roof, the retaining walls and damp in basement rooms.

The report measures the gradient at the address and checks the official landslide maps; the Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here, so the report goes from the house number to the land parcel.

Earthquakes

For Italy's Civil Protection Department, Bioglio 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 0.042 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.
