Vajont Dam Disaster

Vajont Dam Disaster
The Vajont Dam (Vaiont Dam) is a disused dam, completed in 1959 in the valley of the Vajont River under Monte Toc, in the municipality of Erto and Casso, 100 km (60 miles) north of Venice, Itay. On 9 October 1963, during initial filling, a massive landslide caused a man-made megatsunami in the lake in which 50 million cubic metres of water overtopped the dam in a 250 metres (820 ft) wave, leading to the complete destruction of several villages and towns, and 1,917 deaths. This event occurred when the company and the Italian government dismissed evidence and concealed reports describing the geological instability of Monte Toc on the southern side of the basin, and other early warning signs reported prior to the disaster.
