Geologist David Montgomery (David Montgomery) from the University of Washington (University of Washington) found that in Tibetan river Tsangpo Gorge (Tsangpo) in different historical periods there were massive lake that disappeared immediately — crashing into the lowlands monstrous flood waters.
Tsangpo River — the most mountainous in the world — its water run at an altitude of 3.9 km above sea level. It's pretty cool and a lot comes down to the south, is in India, "transformed" into a large lowland river, known as the Brahmaputra.
Montgomery study showed that a few times in the history of the Tsangpo Gorge overlapped with ice so that the water ceased to go down the centuries and accumulated in a giant lake.
Then came the breakthrough ice dams, and all the waters of this lake falls in a lower part of the valley, away from Tibet and on to the plains of India, creating one of the largest flood in the history of mankind.
The last such disaster occurred between one thousand and 1,400 years ago. At this point, the depth of the lake is 235 meters, and the volume of water at one point collapsed down — more than 200 cubic kilometers.
Another such disaster occurred 10,000 years ago. She was even greater. The maximum depth of the lake at that time reached 660 meters, and the volume of water in it — more than 2 million cubic kilometers.
Interestingly, the modern fertile (and cultivated) soil plots in the vast Tibetan stepped terraces of the Tsangpo Gorge owe their origin is that ancient lakes that arose at the same place and suddenly disappear several times.
