In northern Pakistan on January 4, 2010, a landslide blocked the Hunza river. Soon a lake formed behind the landslide, which inundated farms, roads, and homes. Nasa took an image of the new lake in mid-March. Since then, they have taken another image which shows the growing size of the lake. There are some videos of the effects of the landslide on the local population, and the attempts to create a spillway, available here.
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured this false-color image of the landslide lake on the Hunza River on May 2, 2010. Blue indicates water, red indicates vegetation, and shades of beige and gray indicate bare rock. The approximate extent of the lake on March 16, 2010, appears as a white outline. This image has been rotated, so north is to the right.
