"..during initial filling, a massive landslide caused a man-made megatsunami in the lake in which 50 million cubic metres of water overtopped the dam in a wave of [820 feet]," which was only a third of the dam's contents (the other two-thirds being retained).

Prior analysis had clearly identified the geological instability of the dam, but these reports were suppressed. When the dam overflowed, the disaster was worse than expected - the wave ten times higher than anticipated - leading to the "complete destruction of several villages and towns, and 1,917 deaths."

Hailed as the tallest dam in the world, and still ranks among the tallest though no longer in use.

The landslide that overtopped the dam occurred just as Moon rose, almost exactly on the ecliptic (latitude 0N06, about 1° from her north node), square Sun on Nadir, so I suspect gravitational shifts were part of the timing.

The dam didn't collapse. It's still standing. The mountain beside the lake behind the dam collapsed into the lake, causing the water to slop over the top of the dam (on a massive scale) and flood the land below, washing away a bunch of villages and villagers.

It was a politically caused disaster. It was clear to anybody looking that mountain was unstable and several smaller scale collapses caused several floods, including at least one that caused loss of life, before the big one. The local government decided they would be embarrassed if they scrapped the dam so they turned it over to the local power company to generate electricity without mentioning they shouldn't let the lake fill past about 75% of what it was supposed to contain. The power company filled it full and the water soaking into the slope of the mountain destabilized it. And whoops, flood!
