"This is where my furniture factory stood. It was about 30ft above the river, and several dozen feet away from it," says Farmanullah, a businessman in northern Pakistan's Khyber-Pakhtunkhwa province.
But for about 200ft (60m) on either side of where he is standing, in the village of Damorai in Shangla district, it's now a vast bed of rocks and boulders.
