In early January of 2010 a huge landscape destroyed the village of Attabad and dammed the Hunza river in Northwest Pakistan. The landslide dam resulted in the rapid growth of a new lake that has flooded a key road and many villages. NASA’s Earth Observatory website has images (and an early image) showing the flooding.
The lake as now overtopped the landslide dam, its the overflows erosion of this dam is threatening thousands of peope who live downriver. The Boston Globe has collected an fantastic set of photos of this disaster on its The Big Picture.
