114 km or 71 miles The Vajont Dam Location of Vajont, Italy

270 million cubic meters of earth slide Landslide reached 68 mph Caused an 820 ft wave that overtopped that dam Destroyed 6 Italian villages 2,000 + people died.

1960 - 70,000 cubic meters of soil slid

Effects of Rapid filling and drawdown

Failure planes Thin layer of clay in the limestone was the failure surface. Some argue that this surface remains from an ancient landslide.
