Castellavazzo is a comune (municipality) in the Province of Belluno in the Italian region of Veneto, located about 90km (60miles) north of Venice and about 20km (10miles) northeast of Belluno. As of 31 December 2004, it had a population of 1,735 and an area of 18.8km2.[1]
On 9 October 1963 at 10:35 pm, heavy rainfall and the 3rd drawing of the Vajont Dam triggered a landslide. It was 270e6m3 of rock, forest and earth that slid into the Vajont Dam at 110km/h. This then caused a 250m (820feet) high tsunami that overtopped the dam and flooded Castellavazzo and other villages such as Longarone, Pirago, Rivalta, Villanova, Faè, Erto e Casso and Codissago. There was also damage caused by air being displaced from the wave. About 2,000 people were killed in the landslide and tsunami, but the main structure of the dam is still there, and many tourists come to see it.
Castellavazzo borders the following municipalities: Erto e Casso, Forno di Zoldo, Longarone, Ospitale di Cadore.
