Nonio, on the western shore of Lake Orta

Nonio looks over Lake Orta from the western side, among woods and terraces, a short distance from Omegna, the small town at the northern tip of the lake known for its kitchenware industry. From the village the view takes in the water and the hills on the opposite shore; below, the road follows the lake.

Many residents work in Omegna and the other towns around the lake, or further away towards Novara and Verbania. Declared average income is above the provincial figure. Istat, the national statistics office, counted 827 residents at the end of 2023, down 5.8% on 2011; the average age is 48.2, slightly below the 49.0 of the province, and over-65s are 26.4%.

Buyers will mostly find detached houses and small villas on the slope, with gardens and views, and a few stone buildings in the old core. On a hillside like this, check access first: gradient of the road, parking, manoeuvring in winter. Then damp in walls set against the slope, insulation and the boiler, since the climate zone is E.

Earthquake risk is low. Nonio is in seismic zone 4, the lowest in the Civil Protection classification, like 46 of the 74 municipalities in the province, with an expected ground acceleration of about 0.046 g.

The Revenue Agency (Agenzia delle Entrate) cadastre is published and the report links the address to its land parcel. On the slope down to the lake, streams and landslides are read on the official maps for the individual plot, along with the distance to schools, shops and pharmacies measured from the house.

Key points

  • Western side of Lake Orta, near Omegna.
  • Average income above the provincial average.
  • Seismic zone 4, like 46 of 74 municipalities in the province.

Overview

Nonio is a municipality in the province of Verbano-Cusio-Ossola, in Piemonte. At the end of 2023 it had 827 residents, ranked 37 of 74 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Nonio is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (46 of 74) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.046 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.
