Santi Cosma e Damiano, the Aurunci hills above the Garigliano
At the far southern edge of Lazio, close to the border with Campania, Santi Cosma e Damiano sits on the slopes of the Aurunci mountains overlooking the Garigliano plain. The sea at Minturno and Scauri is a few kilometres away, and Formia and Gaeta are the largest towns nearby. The land rises from olive groves in the lower part to woods and pasture on the mountain.
The municipality has a hilltop centre and scattered hamlets lower down. People working in Formia, Gaeta or Campania nearly always drive; the nearest station on the Rome-Naples line is Minturno-Scauri. The market includes village houses, often old and on several floors, and detached homes among the olive trees, where access, utility connections and building permits need checking.
The population is almost stable: 6,843 residents in 2023, just 0.6% fewer than in 2011. The average age of 45.4 matches the province of Latina, over-65s are 23.5% of residents and foreign nationals 4.6%. Average declared incomes are below the provincial level.
In the province of Latina, 30 municipalities are in seismic zone 3 and 3 in zone 2 of the national classification used by the Civil Protection Department. Santi Cosma e Damiano is in zone 3, with an expected ground acceleration of about 0.098 g, a moderate to low value. For masonry houses in the centre, it is still worth asking about the state of floors and roofs and whether the structure has ever been repaired.
On the Aurunci slopes, the hazard to check is landslides and rockfall; lower down, it is the ditches and canals of the plain. The report reads both for the specific address on the official maps.

Earthquakes
For Italy's Civil Protection Department, Santi Cosma e Damiano 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.

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