Italy's Infamous Vajont Dam
Contributor Daniele Bolgia created this memorable drone video of a famous but never-used dam in northern Italy. Vajont Dam was constructed in the 1950's as a means to harness the Vajont River in the Veneto region. In October, 1963, as its reservoir was being filled, a massive landslide into the lake caused a giant wave of water to come pouring over its wall, the tallest in the world at the time. The resulting "tsunami" killed almost 2,000 people, making it one of history's worst dam accidents.
