An unexplained blast Thursday has local residents concerned and shaken up. The shock waves were felt within about a 12-mile radius in the Morrison's Cove area of Martinsburg. Police said they got reports from all over the area asking what caused what people are describing as a blast. There are no reports of any injuries or damage, but there is still no explanation for the blast and police said they've ruled out fracking.

I did check with New Enterprise, said Chief of Martinsburg Police Kerry Hoover. They aren't blasting and they haven't blasted for a while and when they blast we don't feel those percussions up here. We are checking on some things that it could have been but we are not sure, Hoover said. Anyone with any information about what caused the blast is asked to call Martinsburg police.
