Castelnuovo Belbo, on the Belbo valley floor in the Asti hills

The Belbo stream runs through the hills of the Monferrato around Asti in a broad, farmed valley, and Castelnuovo Belbo sits right on its floor, at around 120 metres. Vineyards cover much of the slopes around it; the village is a farming centre of low houses and farmsteads.

For a buyer, the first question is where the house stands in relation to the stream: as in any valley-floor village, a flat plot near the embankment is a very different proposition from one on the first rise of the hills. The report checks the official flood maps for the exact address, along with the landslide maps for houses on slopes.

Istat, the national statistics office, counted 824 residents in 2023, down 7.9% on the 895 of 2011. The average age of 48.7 is slightly above the provincial 47.9, and over-65s make up 28.4%. Foreign residents account for 12.0%. Declared incomes are below the provincial average.

Seismically the area is calm: Castelnuovo Belbo is in zone 4 on the Civil Protection scale, like 113 of the 117 municipalities in the province, with an expected ground acceleration of about 0.050 g. In a farmhouse or village house, the state of the roof and walls, rising damp and insulation matter more, given that this is climate zone E.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for the municipality, so the report works back from the address to the land parcel and the building.

Key points

  • Valley-floor village on the Belbo, in the Monferrato around Asti.

Overview

Castelnuovo Belbo is a municipality in the province of Asti, in Piemonte. At the end of 2023 it had 824 residents, ranked 48 of 117 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Castelnuovo Belbo is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (113 of 117) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.050 g, a moderate 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.
