Abstract
The Vajont hydropower station dam and reservoir was located at the foot of Mt. Toc in the Dolomite region of the Italian Alps. In October 1963, a large landslide of 260 million m(3) of rock (equivalent of cube with a 650 meter side) filled the reservoir of the dam, initiating a 150–250 m high wave, which overtopped the dam and wiped out several villages in the nearby Piave valley, resulting in the death of at least 1921 people.
