NARRATOR: 1957. 70 miles from Venice,
amid the cliffs and gorges of Italy’s Vajont River Valley,
work begins on the Vajont Hydroelectric Dam. Crucial to the
dam’s operation is a vast reservoir that can hold
44 billion gallons of water. Ever since the filling of
the reservoir in early 1960, enormous cracks have begun
appearing on Mount Toc, above the dam. LUCIA FILIPPIN (IN
ITALIAN): People could sense that something
big was about to happen because the ground was
moving and suddenly, new cracks would appear,
very deep and very large. NARRATOR: Then, in late
1960, another warning sign. This time, it’s a landslide. Though relatively small,
it prompts a flurry of scientific research. What it confirms is shocking. As a direct result of
filling the reservoir, Mount Toc has
become waterlogged, dislodging a 720 million
ton chunk of rock that is now slowly slipping down
the mountain towards the lake below. And so, in 1962, the
authorities lower the water by over 70 feet. At that level, they are
confident the dam can’t be overtopped, provided
the landslide falls into the reservoir at
the speed they expect. Even as locals grow
uneasy, officials remain confident that
the threat is minimal. FRANCESCO NICCOLINI
(IN ITALIAN): No one had been
warned in Longarone. There were no official warnings. There were just the warnings
coming from the mountain. NARRATOR: October 9, 1963. Traveling at over 60 miles
an hour, three times faster than expected, the mile and
a half wide chunk of rock is finally unleashed. In its sights– the
enormous Vajont reservoir. FRANCESCO NICCOLINI
(IN ITALIAN): How can you imagine nine
billion cubic feet of rock breaking away from a mountain
and falling into a basin filled almost to the brim? NARRATOR: It sends two giant
waves in opposite directions, one towards the dam, the other
towards the village of Erto. Traveling in over
30 miles an hour, the first wave engulfs farms
and houses all along the shore, killing most of their occupants. Shielded by a spur in the
mouth, the village of Erto is miraculously spared
the worst of the wave. At the opposite end
of the reservoir, the second tsunami
is now hurtling towards the Vajont Dam. It sends more than 275 million
tons of water over the edge and into the valley below. In its crosshairs, nearly
5,000 inhabitants of Longarone, with nowhere to run. The town is gone,
reduced to little more than mud and rubble. Of the town’s 372 buildings,
just 22 are still standing. The rest flattened and washed
away down the Piave River, towards Venice. ELISA DI BENEDETTO: Longarone
was not there anymore. They could see that Longarone
didn’t exist anymore. There was only mud
and water and ruins. No life at all. NARRATOR: The violent disaster
claimed almost 2000 lives, making it one of the worst
man-made disasters in history.

    This disaster is clearly the fault of Donald Trump for pulling the US out of the Paris Climate Change Agreement.
    Some may question how this could be the case since the Donald wasn't president yet.

    Dam, it's scary. Now I wonder what are the safety guidelines/requirements before making reservoirs on a location… how do engineers hold mountains below it…. do they check the mountain's ability not to sip water? How is that? I got lotsa questions.

    And to think, the water just jumped off the spillway walls (please correct this term) is UGH! It held the tons of soil.

    I don't think in general, people realize how powerful and heavy water is! Not even a mountain can hold it back if a lot of water builds up force against it! Sadly, Vajont Dam proved that. (And moving water is even more forceful, standing in even 6 to 8 inches of water can knock you off your feet if it is moving fast enough!)

Out of two whole towns 13 people survived! Basically, Italy needs better engineers like NOW! If they tell you the dam is safe move immediately or you may die!

    Smithsonian Channel – You've got some problems with the statistics in your video. At 00:12, you say that the reservoir is built to hold "44 billion gallons of water". But at 02:55, you say that the tsunami that went over the face of the dam, weighed "275 million tons". One ton of water is 150 gallons (1 Ton being 2000 lbs, divided by the weight of one gallon, roughly 8 lbs). 275 million tons of water would be nearly 69 billion gallons of water.

    So what you are implying is that the tsunami went in two directions, but the wave that went over the dam encompassed 25 billion gallons more than the reservoir was even capable of holding, this despite the level of the water in the reservoir being significantly lowered (1:20 – lowered by 70 feet). Maybe you should make some adjustments to the numbers you put out, they don't work.
