It was reported that Kim had died of a suspected heart attack on 17 December 2011 at 8:30a.m. while travelling by train to an area outside Pyongyang. It was reported in December 2012, however, that he had died in a fit of rage over construction faults at a crucial power plant project at Huichon in Jagang Province. He was succeeded by his youngest son Kim Jong-un, who was hailed by the Korean Central News Agency as the Great Successor. According to the Korean Central News Agency (KCNA), during his death a fierce snowstorm paused and the sky glowed red above the sacred Mount Paektu and the ice on a famous lake also cracked so loud that it seemed to shake the Heavens and the Earth.
