The Sago Mine disaster was a coal mine explosion on January 2, 2006, in the Sago Mine in Sago, in Upshur County, West Virginia, USA, near the county seat of Buckhannon. The blast and collapse trapped 13 miners for nearly two days. One of the 13 trapped miners survived. It was the worst mining disaster in the United States since the Jim Walter Resources Mine Disaster in Alabama on September 23, 2001, and the worst disaster in West Virginia since the 1968 Farmington Mine Disaster. It was exceeded four years later by the Upper Big Branch Mine Disaster, also a coal mine explosion in West Virginia, which killed 29 miners in April, 2010.
