Itri, on the Appian Way between Fondi and Formia

Itri lies in a valley in the Aurunci mountains, on the Via Appia as it runs down from Fondi towards Formia and the Gulf of Gaeta. The old town climbs a hill topped by its castle, while newer districts have spread towards the road and the countryside. It is the home town of Michele Pezza, the brigand known as Fra Diavolo, and of the Itrana olive, the variety used for Gaeta olives.

Olive groves cover the surrounding hills, and many scattered houses stand among the trees, reached by country lanes. In the historic centre homes are built of stone over several levels, with steps and alleys that cars cannot enter. Inland Itri is a common choice for people who work in Formia, Gaeta or Fondi; the beaches of Sperlonga and Formia are close, and for Rome and Naples the train leaves from Formia station.

Istat, the national statistics office, counts 10,431 residents, almost unchanged since 2011 (down 0.3%). The average age is 46.4, a little above the province of Latina, and 24.8% are over 65 against 22.8%. Foreign residents make up 8.0%. Declared incomes are below the provincial average, and the climate is mild (climate zone C).

The seismic picture is middling. Itri is in seismic zone 3, like most of the province, with an expected ground acceleration of about 0.083 g; only 3 municipalities in the province are in zone 2, among them Cori in the Lepini mountains. For stone houses in the centre, the condition of load-bearing walls and floors still matters.

The limestone hills and sloping streets bring a risk of landslides and rockfall in some spots, and on the valley floor a risk of flooding in heavy rain. The report checks both for the address. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps.

Earthquakes

For Italy's Civil Protection Department, Itri is in seismic zone 3, a zone where strong earthquakes are possible but rare. The region uses a finer breakdown: here the classification is 3A. Most municipalities in the province (30 of 33) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.083 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Population

Compared with the 2011 census, the number of residents is nearly unchanged. The estimated average age is 46 years, in line with the province. 25% of residents are over 65 (the regional figure is 23%). Foreign residents make up 8.0% of the population. On average, a household has 2.2 members.

Itri is in climate zone C, with 1,387 heating degree days: heating may be switched on from 15 November to 31 March, for up to 10 hours a day. The same table puts the town hall at 170 metres above sea level.
