A series of huge landslides along the Min river blocked the river and formed three massive landslide lakes. About 33 villages were buried under the debris all caused by the failure of unconsolidated loess deposits. An anecdotal time to failure curve is presented, based on eyewitness accounts and observations of instability. Climate and climate change controls precipitation and snowmelt (frequency, intensity and magnitude, seasonality, cyclonality and the respective changes), and are the most important external drivers for landslides and flooding. More recently, the U.S. Geological Survey estimated annual losses to be between $2 billion and $4 billion per year. Regular readers will know that one of my interests lies in trying to get a better understanding of the loss of life associated with landslides. Kneale, 1985. .

Much of the debris flow material was deposited before the slide reached the valley bottom, but the frontal part of the slide began increasingly to incorporate loess material and to accelerate. For the Khait landslide itself they conclude that about 800 fatalities is probably a reasonable estimate - note that this very considerably less than earlier estimates. Losses from landslides in the United States were estimated in 1980 to exceed $1 billion per year.

The gravitational pull that facilitates a collective movement of soil, rock, and debris down a steep slope is called a landslide. Huge boulders in the landscape can be signs of past debris flows. A dormant stratovolcano suddenly erupted destroying many towns and villages. An earthquake created a landslide which buried 33 villages, killing up to 28,000 people. [2] At the same time the Tajik Basin is being shortened in response to oblique collision with the Pamirs, forming a series of north-south to SW-NE trending thrust faults, the earthquake is thought to have been caused by movement on the Vakhsh thrust, one of these faults. They develop during intense rainfall, runoff, or rapid snowmelt, changing the earth into a flowing river of mud or slurry ..

The river is known to have begun cutting the valley through the glacial sediments roughly 12,000 years ago, suggesting an average recurrence rate of about 500 years based on the 25 landslides. 3 What main factors cause landslides and floods? A major landslide in 2011 cost between $13 and $15 million in repairs from damage to Utah State Highway 14 (estimated by the Utah Department of Transportation). From February 20 to March 28, 2012, the project had carried out Regional Characterization Study in order to identify potential risks both in Tajik and Afghan target territories and had developed hazard maps following the assessment. Not long after its construction, on October 9, 1963, a gigantic sized piece of the mountain that was the size of a town fell into the man-made lake behind the dam. Because a recurrence for such a landslide cannot be established, it is not possible to develop a meaningful estimate of annual per capita damages.
