Monte Toc
Monte Toc, nicknamed the walking mountain by locals due to its tendency to landslide, is a mountain on the border between Veneto and Friuli-Venezia Giulia in Northern Italy best known for the Vajont Dam, which was built at the mountain's base in 1960.
On October 9, 1963, 260 million cubic metres of rock slid down the side of Mount Toc and plunged into the reservoir created by the Vajont Dam, causing a megatsunami 250 metres high over the dam wall and destroying the town of Longarone and its suburbs. 1,918 people were killed, 1,450 of whom were in Longarone.
