Trasaghis, Lake Cavazzo and the Tagliamento valley

Trasaghis stretches along the shore of Lake Cavazzo, also called the lake of the Three Municipalities, and towards the Tagliamento valley, at the foot of the Julian and Carnic Pre-Alps. The municipality is made up of several hamlets, including Alesso, Avasinis, Braulins and Peonis, each with its own character. Gemona and Udine are the reference towns for work and services, reached by car.

The landscape alternates lake, meadows, woods and steep mountains, with a climate wetter than the Friulian plain. For a buyer the hamlet makes the difference: some are near the water and the lakeside paths, others more tucked in at the foot of the slopes. The climate zone is E. Near the lake and the Tagliamento, check the official flood maps for the address in the report.

According to Istat, the Italian national statistics office, there were 2,088 residents in 2023, down 9.1% on 2011. The average age is 50.3, above the 48.5 of the province of Udine, and over-65s make up 30.1%. Foreign residents account for 4.5%. Declared incomes are below the provincial average.

The municipality is in seismic zone 1, the highest, with an expected ground acceleration of 0.259 g. Much of the housing in this area was rebuilt after the 1976 earthquake: when buying, ask when and how the building was rebuilt and for the structural paperwork.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report traces the plot from the address, with the official landslide maps for that spot.
