Jan. 4, 2010, in a remote valley of Hunza in northern Pakistan strongest landslide buried a village Attabad, destroying 26 houses, killing 20 people and blocking the river Hunza. As the newly-lake authorities rushed to evacuate local residents and help victims of the landslide. Now the lake is 91 meters deep and 16 km in length, it absorbed most of the highways, farms and homes. Earlier this week, the lake reached the top of the natural dam and began pouring. This rapid erosion of landslide debris forced the authorities worried about the potential breakthrough of the dam, and local residents began to leave their homes.
