The Dam That Survived Its Own Destruction

[00:00:00]Scientists predicted the exact mountainside that would collapse and kill 2,000 people and they were completely ignored. This is the Vajont Dam disaster of 1963 and it's not really about engineering failure at all. It's about a warning nobody listened to.

[00:00:15]Geologists had [music] flagged a massive slab of limestone on the mountainside above the reservoir, 270 million [music] cubic meters of it and said it was unstable. They were right.

[00:00:25]On October 9th, 1963, that entire [music] slope just detached and fell straight into the reservoir. When it hit the water, something catastrophic happened. The impact displaced so much water so fast that it created a wave 250 [music] meters tall. That's the height of a 75-story building. That wave [music] traveled over the dam in a single second, overtopping it completely. Then it kept going, crushing everything in its path for 2 kilometers inland.

[00:00:51]Five entire villages were erased in just 45 [music] seconds. 2,000 people were gone, but here's the twist nobody expects. The dam itself, [music] it survived. It's still standing there today, completely intact, looking down over a valley that will never be the same.
