Viarigi, a hilltop village in the Asti Monferrato

On a hilltop in the Asti part of Monferrato, with open views over farmed countryside, stands the village of Viarigi. The historic centre is compact, with brick houses packed along sloping streets; outside the village the countryside alternates vineyards, cereal fields and woods in the cooler valleys.

People look to Asti and the larger towns nearby for work and services. Buyers here usually want space and quiet: a village house with a courtyard or a farmhouse with some land. Monferrato brick houses often have cellars dug into the ground, useful but worth checking for damp and leaks.

Istat, the national statistics office, counted 839 residents at the end of 2023, 116 fewer than in 2011, a fall of 12.1%. The average age is 51.7, against 47.9 for the province, and over-65s are 29.8%. Foreign residents make up 6.9% and declared average income is close to the provincial figure, slightly below it.

Viarigi is in seismic zone 4 of the Civil Protection classification, like 113 of the 117 municipalities in the province, with an expected ground acceleration of about 0.043 g. Earthquakes matter little here; the ground the house stands on and the drainage of rainwater around the walls matter more.

The Revenue Agency (Agenzia delle Entrate) cadastre covers the municipality and the report traces the address to its land parcel, reading the official landslide and flood maps for the plot: in hill country the difference between a ridge and a valley floor is sharp.

Overview

Viarigi is a municipality in the province of Asti, in Piemonte. At the end of 2023 it had 839 residents, ranked 47 of 117 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Viarigi 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 0.043 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.

Population

Compared with the 2011 census, the resident population has fallen by 12.1%. The estimated average age is 52 years, higher than the province average (48). 30% of residents are over 65 (the regional figure is 27%). Foreign residents make up 6.9% of the population. On average, a household has 2.0 members.
