Mezzana Mortigliengo, hills and hamlets east of Biella
The name itself tells you where you are: Mezzana belongs to the Mortigliengo, a group of wooded hills in the eastern Biella area dotted with small hamlets. The town hall stands at around 420 metres and the houses are spread over several clusters along roads that rise and fall between the valleys. For work and services, people look to the larger towns of the area and to the city of Biella.
It is an elderly municipality even by the standards of the province of Biella. In 2023 there were 476 residents, 15.2% fewer than in 2011 according to Istat, the national statistics office; the average age is 55.5 against 49.7, and over-65s make up 40.8%, against 30.1% in the province. Foreign residents are 4.8%. Average declared incomes are slightly below the provincial average.
The housing is largely hamlet houses in stone and brick, often on two or three floors, and more recent detached homes. In both cases look at insulation and the boiler, since in climate zone E heating is the heaviest cost, and ask when the roof and façades were last redone.
Earthquakes carry little weight: Mezzana Mortigliengo is in seismic zone 4, the lowest on the Civil Protection department's national scale, like 49 other municipalities in the province, with an expected ground acceleration of about 0.041 g.
Water and slopes matter more. Among wooded hills and small streams, landslide and flood hazard depends on the exact spot, and the report reads it on the official maps for the address. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the address leads to the land parcel.

Earthquakes
For Italy's Civil Protection Department, Mezzana Mortigliengo 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.
