Grumento Nova, the Agri valley and Roman Grumentum
Grumento Nova stands on a hill in the Val d'Agri, in south-western Basilicata, at around seven hundred and seventy metres, looking over the valley and Lake Pertusillo. On the valley floor, within the municipality, is the archaeological park of Grumentum, a Roman town with a theatre, amphitheatre and baths. For larger services people go towards Villa d'Agri and Potenza.
The village has a stone-built old centre gathered on the hilltop, with newer houses along the roads leading down. If you buy in the centre, expect narrow access, work on the wiring, plumbing and roofs, and steep internal stairs. Outside the village there are country houses and farmland. The report measures elevation and gradient at the house and checks the official landslide maps.
Istat, the national statistics office, counts 1,538 residents in 2023, 9.7% fewer than in 2011. The average age of 47.6 is in line with the provincial 47.3, over-65s are 27.8% and foreign residents 6.6%. Declared incomes are below the provincial average.
In the Agri valley earthquake risk needs to be taken seriously: Grumento Nova is in zone 1, like 39 other municipalities in the province, with an expected ground acceleration of 0.258 g. Before buying a masonry house, find out whether it has had seismic upgrading and have a surveyor look at it.
The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report traces the land parcel from the address.

Earthquakes
For Italy's Civil Protection Department, Grumento Nova is in seismic zone 1, the highest-risk zone, where very strong earthquakes are possible. The region uses a finer breakdown: here the classification is 1a. Only 40 of 100 municipalities in the province are in zone 1.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.258 g, a high value: the level with a 10% probability of being exceeded in 50 years, on rock.
For anyone buying in Grumento Nova, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
