Aberfan disaster

On Friday, October 21 1966, 144 people, 116 of them children, were killed when a waste tip containing unwanted rock from the local coal mine? collapsed onto the village of Aberfan? in south Wales. The children killed were mainly pupils at the Pantglas Junior School which was situated close to the tip.

At the Tribunal of Inquiry into the Aberfan Disaster the [National Coal Board]? was found to have been responsible for the disaster due to "ignorance, ineptitude and a failure of communication". The collapse was found to have been caused by a build up of water in the tip - when a small rotational slip occurred the saturated fine material of the tip liquified and it flowed down the mountain.
