Strona, in the wool-mill valley of eastern Biella

The valley of the Strona di Mosso stream, in the eastern part of the Biella area, has been wool-mill country for generations, and Strona takes its name from it. The village stands at around 450 metres among woods and small hamlets scattered over the slopes, with workers' houses and factory buildings that tell the textile history of the area. For services and work people look to Biella and to the towns on the plain towards Cossato.

Buying here often means choosing between detached houses with some land on the slopes and flats in small blocks. The climate is cool and damp (climate zone E), and in older houses insulation and the boiler account for a large share of running costs. Valley roads are narrow and steep: in winter it helps to know how you will get home.

In 2023 there were 939 residents, 18.8% fewer than the 1,157 of 2011. The average age is 52.1, against 49.7 in the province of Biella, and over-65s make up 31.6%. Foreign residents account for 5.2%. Declared incomes are slightly below the provincial average.

Seismic hazard is low: Strona is in zone 4, like 50 of the 74 municipalities in the province, with an expected ground acceleration of 0.042 g. In a narrow valley, how streams and slopes behave in heavy rain matters more.

The Revenue Agency (Agenzia delle Entrate) cadastral maps cover the municipality. From the address the report finds the parcel and checks the official landslide and flood maps, which along the stream and on the slopes need reading house by house.

Key points

  • Strona di Mosso valley, among wool mills and woods.

Overview

Strona is a municipality in the province of Biella, in Piemonte. At the end of 2023 it had 939 residents, ranked 40 of 74 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Strona 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.
