The biggest bomb
In winter 1911 a huge landslide that occurred in the Pamir Mountains, in south-eastern Tajikistan, completely blocked the valley Bartang (Murghab) - the upper reaches of the Amu Darya. The resulting earthquake Usoi blockage was called by name of the village, which was buried under the rubble, which killed all the inhabitants of the village Usa.
Dam is the highest dam in the world (the height of 567 m, the amount of 2, 2 km3).
For the rubble formed a large lake was formed, which in October 1911 absorbed the village Sarez, after whom the lake was formed came to be called "Sarez."
Now the water volume of 16 cubic kilometers located at an altitude of 3 km above sea level. The smallest height of the edge of a natural dam above the water level - 38 m.
Dam continuously oozes dozens of springs.
With the destruction of the dam wave swept over the fertile valley of the Amu Darya, 6 hours to reach the Aral Sea, once again filling it to the brim.
Water lomanetsya the old riverbed Bartang.
If Google punch line for Bartang, and then on the Amu Darya, the Aral goes to about 1800 km.
When going from a height of about 3 km in the amount of at least 10 cubic meters. km. water will increase in volume by 10 times due to wash-off the top layer of rock and soil, dust, small (up to 10 tons) of stones, and all that meet on the way.
It will be a mudslide. Ferghana valley will cease to exist.
The problem Sarezkogo lake the more urgent that before the disaster are only a few years - the water rises to the upper portion of the dam during the ice melting to a height of 10 meters. Every year, the gap is narrowing.
The dam may simply not survive. What will happen after the break to think not even want to.
Solutions to the problem, turned out to this time:
1. pump water pumps (very expensive)
2. dig a tunnel in the mountain 20 km long and drains water to the neighboring valley of (very expensive)
3. Carefully disassemble the top of the dam and let the water flow down (risk)
4. carefully, piece by piece, to drop into the water dangerously hanging over the lake a piece of the mountain, which can inflict a disaster when an earthquake (very risky)
5. slowly pour the top layer of non-mineralized water and sell it to Iran, the proceeds to build a tunnel.
