Treville, Monferrato hills near Casale

The hills of the Casale Monferrato area begin just south of the Po, and Treville is one of the villages on them, at around three hundred metres, with vineyards, fields and patches of woodland all round. The centre is gathered on the hilltop around the church and a few streets; the other houses are spread along the ridge roads. Casale Monferrato is the town people rely on for schools, hospital, shops and the railway station.

Most houses for sale are brick buildings, often large, with a courtyard and outbuildings, built for farming families. They need attention to the roof, timber floors and the wiring and plumbing, and they are expensive to heat in winter, as this is climate zone E. In return they offer space and a well kept farming landscape a short drive from Casale.

According to Istat, Italy's national statistics office, there were 267 residents in 2023, just below the 271 of 2011, a dip of 1.5%. The average age is 52.3, above the 48.9 of the province of Alessandria, and over-65s make up 31.1%. Foreign residents account for 3.4%. Declared incomes are close to the provincial average, slightly below.

Treville is in seismic zone 4, the lowest on the Civil Protection Department's scale, along with 59 other municipalities in the province, and expected acceleration is about 0.039 g. On these clay hills the stability of the ground matters more: cracks in walls or uneven floors should be explained before you sign. The report shows the official landslide maps at the address, starting from the Revenue Agency's cadastral maps, which are available here.

Treville is a municipality in the province of Alessandria, in Piemonte. At the end of 2023 it had 267 residents, ranked 163 of 187 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Treville is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Only 60 of 187 municipalities in the province are in zone 4.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.039 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.
