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. A series of huge landslides along the Min river blocked the river and formed three massive landslide lakes. Armero Tragedy. Most of the landslides occurred along the sides of the Yasman River valley, a tributary of the Surkhob River, caused by the failure of unconsolidated loess deposits. Just clear tips and lifehacks for every day, Landslides include a wide range of phenomena involving downslope ground movement, such as rockfalls, deep slope failure, shallow debris flows, and avalanches.

[2], The total distance travelled by the flowslide is 7.4 km. The southern margin of the Tien Shan is characterised by combination of dextral strike-slip faulting and southward thrusting over the Tajik Basin to the south along the Gissar-Kokshaal fault zone. Other kishlaks were destroyed by loess flowslides in the lower Obi-Kabud River valley and on the north side of the Surkhob River valley. It has been 11 days since the town of Oso, north of Seattle,. In a typical year in the United States, expansive soils cause damage to more homes than earthquakes, floods, hurricanes, and tornadoes combined.

The entire village transformed into a messy graveyard and only about 350 people were impressively saved, 300 of which were children, all of who went to the local circus. Almost a hundred villages were devastated, taking about 5,100 lives. This flow continued down the valley floor for more than another 4,000 m, despite the relatively low slope (3.6). 'Khait' is a transliteration from Russian: ; local modern spelling: Hoit (Tajik: ). [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. Landslides can be caused by natural or human events. This gives a total fatality count of about 7,200 far lower than previous counts, but still substantial of course. .

The adjacent valleys of Yasman and Khait were the most affected by these earthquake-induced landslides. The Haiyuan tragedy struck on the evening of December 16, 1920. For example, water supplies, fisheries, sewage disposal systems, forests, dams, and roadways can be affected for years after a slide event. (2009 in press). you are here 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. In December of 1941, the residents of Huaraz, a Peruvian city in the Ancash region, were completely unaware that a retreating glacier tongue above their city would soon be responsible for wreaking havoc its people and claim thousands of the lives living within.

Hence, the lethal waters, laden with debris from dam construction and large volumes of mud and rocks, inundated towns and villages and buried all forms of life that came in its way. 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.
