The wall of water that overtopped the dam by 250 metres and destroyed field notes from a catastrophe pdf village and all nearby villages on 9 October 1963 would have obscured virtually all of the blue sky in this photo. 2017 is still one of the tallest in the world.
This event occurred when the company and the Italian government dismissed evidence and concealed reports describing the geological instability of Monte Toc on the southern side of the basin, and other early warning signs reported prior to the disaster. Numerous warnings, signs of danger, and negative appraisals had been disregarded, and the eventual attempt to safely control the landslide into the lake by lowering its level came when the landslide was almost imminent and was too late to prevent it. Although the wave only contained a third of the dam’s contents, it was still ten times higher than calculations had predicted. Minister of Finances for several years. 168,715,000 cubic meters of water. The dam and basin were intended to be at the centre of a complex system of water management in which water would have been channeled from nearby valleys and artificial basins located at higher levels. Tens of kilometres of concrete pipes and pipe-bridges across valleys were planned.
SADE stated that the geology of the gorge had been studied, including analysis of ancient landslides, and that the mountain was believed to be sufficiently stable. Construction work started in 1957, but by 1959 shifts and fractures were noticed while building a new road on the side of Monte Toc. This led to new studies in which three experts separately told SADE that the entire side of Monte Toc was unstable and would likely collapse into the basin if the filling were completed. All three were ignored by SADE. Construction was completed in October 1959, and in February 1960, SADE was authorised to start filling the basin. Throughout the summer of 1960, minor landslides and earth movements were noticed. However, instead of heeding these warning signs, the Italian government chose to sue the handful of journalists reporting the problems for “undermining the social order”.
