Casasco, in the hills of the Tortona Apennines

Casasco sits in the hills of the Tortona Apennines, at around four hundred metres, where the plain around Tortona starts climbing towards the Apennines. It is a tiny place, with a few houses grouped together, scattered farmhouses, fields and woods. Tortona is the town people rely on for schools, the hospital and the railway, and from there motorways lead to Genoa and Milan.

The population is almost stable. Istat, the national statistics office, counted 121 residents in 2023, 3 fewer than the 124 of 2011, a fall of 2.4%. Foreign residents make up 14.9%, and the estimated average age is 52.6. Over-65s account for 35.5%, against 28.6% in the province. Declared incomes are above the provincial average.

Most houses for sale are country homes and farm buildings. What matters in these purchases is the road in, connections to mains water and sewers (or a well and septic tank where there are none), and the state of the roofs. The report measures real distances to pharmacies, schools and shops from the address.

Casasco is in seismic zone 3 of the Civil Protection Department's scale, with 126 other municipalities in the province of Alessandria; another 60 are in zone 4. Expected ground acceleration is about 0.095 g. If you buy a farm building to restore, the works are a chance to improve its structural strength as well.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report works back from the address to the plot. On slopes, landslide hazard should be checked on the official maps for each house.

Earthquakes

For Italy's Civil Protection Department, Casasco is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (127 of 187) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.095 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

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

The estimated average age is 53 years, higher than the province average (49). 36% of residents are over 65 (the regional figure is 27%). Foreign residents make up 14.9% of the population.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 9 inhabited census areas in Casasco. Half of the residents live in areas scoring 55 or more.
