Ponna, a Valle d'Intelvi village between two lakes

The Valle d'Intelvi covers the upland and slopes between Lake Como and Lake Lugano, and Ponna is a small municipality in the valley, with houses at about eight hundred and seventy metres among woods and hay meadows. It is mid-mountain country, with an old stone core, a few hamlets and narrow roads linking the village to the rest of the valley. For the hospital, secondary schools and offices, Como is the main reference.

The property market is tiny and made up of village houses, rustic buildings and a few second homes used in summer. Buyers need to reckon with climate zone F, which means long, snowy winters, and to weigh up insulation, heating and access carefully. Average declared incomes are much lower than the provincial average.

In 2023 Istat, the national statistics office, counted 238 residents, down 10.9% from 267 in 2011. The estimated average age is 54.3, against 46.3 in the province of Como, and over-65s make up 36.6%, compared with 24.1%. Foreign residents are few, 2.1%.

Earthquakes are not the main concern here: all 147 municipalities in the province are in seismic zone 4 on the Civil Protection scale, and in Ponna the expected ground acceleration is about 0.039 g. The slopes matter more: gradient, landslides and streams are checked for the address in the report, using the official maps. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report traces the land parcel from the address.

Earthquakes

For Italy's Civil Protection Department, Ponna is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 147 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.039 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.
