Rocca d'Arazzo, a hilltop village by the Tanaro near Asti
The name gives it away: rocca means a rock or stronghold, and the old centre of Rocca d'Arazzo sits on top of a hill above the Tanaro river plain, a short way from Asti. The old village clusters around the church at the top; further down, along the roads towards the valley floor, there are newer houses, farmsteads and vineyards.
For buyers, the main draw is how close Asti is. It is a short drive, and with it come the railway station, secondary schools and the hospital. The village itself has few services. Houses in the centre are brick, often on two or three floors with small courtyards; out in the country there are farmhouses with land, which take more upkeep. Living up on the hill and living down on the flat are different things: on the hill, look at slopes and landslides, near the Tanaro, at the flood maps.
In 2023 there were 923 residents, down 2.2% on 2011, according to Istat, the national statistics office. The population is a little older than the Asti average: the average age is 50.5 against 47.9, and over-65s make up 30.9% against 27.3%. Foreign residents account for 10.4%. Declared incomes are in line with the provincial average.
The earthquake picture is calm. Rocca d'Arazzo is in seismic zone 4, as classified by the Civil Protection Department, along with 112 other municipalities in the province of Asti; only 4 are in zone 3. Expected ground acceleration is 0.043 g. In older houses, damp, roofs and the heating and electrics matter most.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here, so the report goes from the house number to the land parcel and checks that exact spot against the official landslide and flood maps.

Earthquakes
For Italy's Civil Protection Department, Rocca d'Arazzo is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (113 of 117) are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.043 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.
