Terrifying that this could happen as recently as 2008 and, I'm sure, with better understanding of potential consequences.

In 1966, something similar (although with a mining waste dump, instead of ash) happened in Aberfan, Wales (in the UK) with a more tragic outcome[1].

The question should be whether this occurred due to ignorance or ignoring the lessons of history, which rhymes if not repeats.

This was featured in an episode of The Crown [0]. I had never heard of it and didn't know what the episode was going to be about. I think they did a good job conveying the magnitude of the tragedy.
