What happened at the vajont dam in Italy in 1963?
On October 9, 1963, a landslide in Italy leads to the deaths of more than 2,000 people when it causes a sudden and massive wave of water to overwhelm a dam. The Diga del Vajont dam was built in the Vaiont Gorge to supply hydroelectric power to Northern Italy.
Does the vajont dam still in use?
The dam remained almost intact and two thirds of the water was retained behind it. This event occurred after ENEL and the Italian government concealed reports and dismissed evidence that Monte Toc, on the southern side of the basin, was geologically unstable.
What happened with the vajont dam?
On October 9, 1963, at 10:39 pm 260 million cubic meters of rock broke off from the top of Monte Toc, on the border between Veneto and Friuli Venezia Giulia. It fell into the reservoir of the Vajont Dam, producing an enormous wave of at least 50 million cubic meters of water.
How tall was the vajont dam tsunami?
At the moment of the impact the reservoir contained 115 million cubic meters of water. The landslide pushed part of the water out of the lake, producing a wave with a maximal height of 230-240 meters.
What caused the vajont dam slide?
A slope stability failure occurs when the weight of a soil and rock mass overcomes the soil’s shear resistance along a failure plane. The Vajont slide occurred because of combined effects of a rising reservoir and heavy rainfall – water within the soil reducing shear strength – reactivating a historic failure surface.
Why was Vajont Dam built?
Vajont Dam was built to create a reservoir from a mountain stream in order to generate hydroelectric power. Before construction, engineers and geologists were warned by locals that the land surrounding the foot of mountain Monte Toc, the planned site for the dam, was unstable.

Was ist die Vajont-Staumauer von Longarone?
Die Vajont-Staumauer von Longarone aus gesehen. Der Wald hinter der Mauer wächst auf dem Schuttberg der Katastrophe vom Oktober 1963. Die Vajont-Staumauer in den Alpen im Nordosten Italiens (100 km nördlich von Venedig) wurde ab 1956 zur Aufstauung des Flusses Vajont errichtet.
Was sind die aufstauen des stausees Vajont?
Das Aufstauen des Stausees Vajont führte zu einem Bergrutsch vom Monte Toc in den See. Dieser verursachte eine große Flutwelle, die sich über die Mauerkrone in das enge Tal ergoss und das Städtchen Longarone, die Ortschaften Faé, Villanova, Erto sowie fünf weitere vollständig zerstörte. Bei der Katastrophe starben etwa 2000 Menschen.
Was ist die Katastrophe von Longarone (Katastrophe vom Vajont)?
Sie ist durch die „Katastrophe von Longarone“ („Katastrophe vom Vajont“; italienisch strage del Vajont, disastro del Vajont oder tragedia del Vajont) am 9. Oktober 1963 bekannt geworden. Das Aufstauen des Stausees Vajont führte zu einem Bergrutsch vom Monte Toc in den See.
On 9 October 1963, during initial filling, a landslide caused a megatsunami in the lake in which 50 million cubic metres of water overtopped the dam in a wave of 250 metres (820 ft), which brought massive flooding and destruction to the Piave Valley below, leading to the destruction of several villages and towns.
How much does it cost to visit the vajont dam?
Tours last about 40-45 minutes and cost ca. 5 EUR per head.

Was the vajont dam disaster preventable?
The Vajont dam disaster therefore was largely due to human errors, despite having an apparent natural cause, and if some of these errors could have been prevented, then although the landslide would have been likely to still occur, preventions could have been put in place such as evacuation, that would have saved the …
What was the major mistake that the geotechnical engineers made regarding the Vaiont dam disaster?
The engineers tried to control the rate of movement of the slope through decreasing and increasing the reservoir level. After 3 years it was found that the slip rate was increased dramatically. Engineers had no longer the control. Heavy rains made worse the situation.
How many dams are in Italy?
Italy’s 532 dams are constantly monitored.
