Ottiglio, a hill village in the Casale Monferrato area

Among the Monferrato hills, in the Casale area, Ottiglio has its village on a rise and countryside dropping into narrow wooded valleys. Houses in the centre are mostly old stone and brick homes, with farmhouses and hamlets round about. Casale Monferrato is the nearest reference for services and work; Alessandria and Asti are further away.

People buying here usually want a village house or a farmhouse with land, sometimes as a second home. Before signing, check the condition of walls and roofs, damp on the lower floors, the utility connections and car access, which in the hamlets may be along narrow roads. The climate zone is E. Average declared incomes are below the provincial average.

In 2023 there were 563 residents, 109 fewer than in 2011 (down 16.2%), according to Istat, the national statistics office. The estimated average age is 51.5, against 48.9 in the province, and over-65s make up 30.7%. Foreign residents account for 9.9%.

The province of Alessandria is split between seismic zone 3 (127 municipalities) and zone 4 (60) in the Civil Protection classification. Ottiglio is in zone 4, with an expected ground acceleration of about 0.040 g, a low hazard.

On the Monferrato hills the issue to watch most closely is slope stability: landslides and slips depend on the precise spot, and the report reads them for the address on the official maps. The Revenue Agency (Agenzia delle Entrate) cadastral maps are published, so the report also traces the land parcel and helps show which land comes with the house.

Overview

Ottiglio is a municipality in the province of Alessandria, in Piemonte. At the end of 2023 it had 563 residents, ranked 109 of 187 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Ottiglio 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 0.040 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.
