The Aberfan disaster was the collapse of a colliery spoil tip on 21st October 1966 in the village of Aberfan in Wales. Heavy rain caused the tip to slide downhill as a slurry, killing 116 children and 28 adults as it engulfed Pantglas Junior School and other buildings. The National Coal Board were to blame after ignoring warnings regarding heavy rain and possible landslides.
The Aberfan Disaster Memorial Fund (ADMF) was established on the day of the disaster. They received £1.75 million, of which £150,000 had to be paid to the NCB to remove the tips. This was later paid back to them by the British Government in 1997. Many of the villagers suffered medical problems, and half the survivors have suffered post traumatic stress in their lives.
