The Aberfan Disaster: The Day the Mountain Came Down

On the last morning before half term, 240 children walked into Pantglas Junior School beneath a mountain of coal waste. Minutes after lessons began, Tip 7 collapsed above Aberfan, sending liquefied spoil through homes and classrooms and killing 116 children and 28 adults.

But the Aberfan disaster did not begin with the slide, and it did not end when the rescue stopped. The warning signs had been there: natural springs beneath the tip, earlier slips on the mountainside and concerns that failed to produce action. The tribunal later placed responsibility on the National Coal Board and concluded that the disaster could and should have been prevented.

Told through the experiences of survivors including Phil Thomas, Karen Thomas, Jeff Edwards and Gerald Tarr, this is a story of rescue, grief, institutional failure and the lives shaped by what happened on 21 October 1966. It also follows the fight to remove the remaining tips, the controversy surrounding the disaster fund and the long silence that made healing even harder.
