Gremiasco, in the Val Curone in the Tortona Apennines
Gremiasco is a village in the Val Curone, one of the Apennine valleys running down towards Tortona, in the corner of the province of Alessandria close to the borders with Lombardy, Emilia and Liguria. It sits at about four hundred metres along the Curone stream, with hamlets scattered over the slopes among woods and meadows. Tortona is the town for work, schools and hospital care, and from there motorways and railways head to Milan and Genoa.
The population is old: the estimated average age is 55.2, against 48.9 in the province, and over-65s make up 43.7%, well above the provincial 28.6%. There were 277 residents in 2023, 67 fewer than the 344 of 2011, a fall of 19.5%. Foreign residents account for 8.3%, and declared incomes are slightly below the provincial average.
Buyers will find stone houses in the village and hamlets, rural buildings and a few small detached homes. On the slopes, check retaining walls, drainage and the access road in winter; near the stream the report checks the official flood maps, and on hillsides the landslide maps, for the exact address. Climate zone E brings cold winters.
For earthquakes, Gremiasco is in seismic zone 3, like 127 of the 187 municipalities in the province, with expected ground acceleration of about 0.097 g. On an old stone house, have the roof and the links between walls and floors checked.
Revenue Agency cadastral maps are published.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.097 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.
