Sant'Andrea di Conza, upper Irpinia above the Ofanto valley
In upper Irpinia, on the high ground overlooking the Ofanto valley, Sant'Andrea di Conza is a village at around 660 metres, with an old core gathered on its hill and newer homes along the approach roads. The surrounding landscape is one of fields, pastures and woods, and Lake Conza, the reservoir on the Ofanto, is not far away.
Avellino is a long way off and the roads are hilly, so for hospital care, secondary schools and work people look to the larger towns of upper Irpinia. A car is needed. Winters are cold (climate zone E) and heating costs have to be budgeted for. The report measures the distance from the exact address to the pharmacy, school and shops.
The population is falling: 1,402 residents in 2023 according to Istat, the national statistics office, down 15.6% from 1,662 in 2011. The average age is 48.2, against 46.2 in the province, and over-65s make up 27.6%. Foreign residents account for 11.8%. Declared incomes are below the provincial average.
Earthquakes are the main issue. Sant'Andrea di Conza is in seismic zone 1, the highest class, like 58 of the 118 municipalities in the province of Avellino, and the expected ground acceleration in the built-up area is 0.264 g. Many houses were repaired or rebuilt after the 1980 earthquake: ask when the work was done, for the structural design and for the paperwork on any reconstruction grants.
Landslides and slopes are checked address by address on the official maps, which the report consults together with the cadastral maps of the Revenue Agency (Agenzia delle Entrate).
