Rosasco, the Lomellina plain near the Piedmont border
Rosasco lies in the western Lomellina, the Pavia plain west of the river Ticino, close to the border with Piedmont. The landscape is flat and orderly, with irrigation canals, fields and farmsteads, and the village sits just over 110 metres above sea level. For services and shops people look to the larger Lomellina towns, while Novara and Vercelli, just across the regional border, are often handier than Pavia.
In such a small village the housing market consists of only a few properties: courtyard houses, farmsteads and the odd detached home. If you buy a farmstead, find out which parts are already housing and which are still outbuildings, and check drainage, wells and services. Fog and damp winter cold are those of the Po plain, climate zone E.
There were 541 residents in 2023, 97 fewer than the 638 of 2011, a fall of 15.2%. The average age is 52.3 against 47.1 in the province, and over-65s make up 31.8%. Foreign residents account for 7.4%. Declared incomes are below the provincial average.
Rosasco is in seismic zone 4, the lowest class, along with 26 other municipalities in the province of Pavia; the expected ground acceleration in the village is about 0.039 g.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report goes from the street number to the parcel. On a plain crossed by rivers and canals, the right question concerns flood-prone land, which the report checks on the official maps for the exact address.

Overview
Rosasco is a municipality in the province of Pavia, in Lombardia. At the end of 2023 it had 541 residents, ranked 145 of 184 municipalities in the province.
Earthquakes
For Italy's Civil Protection Department, Rosasco is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Only 27 of 184 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.
