Pozzol Groppo, hills between Tortona and the Oltrepò Pavese

Pozzol Groppo lies in the hills where the Tortona area meets the Oltrepò Pavese, where Piedmont gives way to Lombardy. The municipality is made up of hamlets scattered over ridges and slopes, above three hundred and fifty metres, among vineyards, woods and fields. For services and work people look to Tortona and Voghera, both within driving distance.

The population has fallen sharply. In 2023 Istat, the national statistics office, counted 295 residents, 70 fewer than in 2011, a fall of 19.2%. The estimated average age is 55.1, against 48.9 for the province of Alessandria, and over-65s make up 38.3%, against 28.6%. Households average 1.79 people. Foreign residents account for 4.4%. Declared incomes are in line with the provincial average.

With hamlets spread out like this, the exact location matters more than the municipality's name: some houses are on easy roads, others on ridges reached by narrow climbs. Buildings are mostly farmhouses and rural houses in stone or brick, often large, and need assessing for roof, damp and systems. Winters are cold, in climate zone E.

Earthquake risk is moderate: Pozzol Groppo is in seismic zone 3 under the Civil Protection classification, like 127 of the 187 municipalities in the province, and expected ground acceleration in the built-up area is about 0.094 g. With an older building, the useful question is whether walls and floors were tied together in past work.

On the clay hills between Tortona and the Oltrepò, the ground has to be checked plot by plot: the report for the address reads the official landslide and flood maps and, using the Revenue Agency's cadastral maps, reaches the land parcel.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
