Ausonia, below the Aurunci mountains between Cassino and the sea

Ausonia is a village in southern Lazio, in the province of Frosinone, at the foot of the Aurunci mountains, between the Cassino area and the Gulf of Gaeta. The village is built on a hillside, with the oldest houses clustered at the top and newer homes stretching towards the farmed plain.

Buyers find detached houses, low-rise blocks and family homes in the old centre, generally at modest prices. The location is halfway between two worlds: Cassino, with the A1 motorway, the railway station and the university, is around twenty minutes away, and the sea at Formia and Gaeta takes about as long. So the village appeals both to people who work around Cassino and to those who want a home not far from the coast at inland prices.

Istat, the national statistics institute, counts 2,405 residents in 2023, down 9.2% on 2011. The average age is 46.5, in line with the 46.8 of the province of Frosinone, over-65s make up 24.3% and foreign residents 3.3%. Declared incomes are below the provincial average.

Ausonia is in seismic zone 2, like 58 other municipalities in the province, with an expected acceleration of 0.107 g. With stone houses in the centre, ask what work has been done on the walls and roofs; for buildings from the 1960s and 1970s, ask for the year of the design.

Between hill and plain, the report measures elevation and gradient at the address, checks the official landslide and flood maps and identifies the land parcel with the Revenue Agency (Agenzia delle Entrate) maps.

Earthquakes

For Italy's Civil Protection Department, Ausonia is in seismic zone 2, a zone where strong earthquakes are possible. The region uses a finer breakdown: here the classification is 2B. Most municipalities in the province (59 of 91) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.107 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Ausonia, 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.

Official databases list one contaminated site, or site still under investigation, in Ausonia. The report tells you whether one is close to the address.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Ausonia: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Land registry

The cadastral maps for Ausonia are public: from the address the report finds the sheet and parcel number.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 30 inhabited census areas in Ausonia. Half of the residents live in areas scoring 62 or more.
