[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. 2 the waves rose to a height of 6m causing damage to a number of towns the town of nagahama experienced an outbreak of fire . On steep slopes Crown: un-displaced material still in 2. It travelled with an estimated velocity of about 40m/s.[3]. Landslides triggered by the 1949 Khait Earthquake, Tajikistan, and associated loss of life, Evans, S., Bishop, N., Fidel Smoll, L., Valderrama Murillo, P., Delaney, K., & Oliver-Smith, A. However, a section of environmentalists, scientists, and the educated public think otherwise. Can be cast while in mid-air. Civil Engineering PowerPoint Presentations, 10. In the Yasman River valley, which lies almost entirely within the area of greatest felt intensity, a large number of such flowslides coalesced in tributary valleys before combining into one massive flowslide that travelled the length of the valley. The disaster struck the southern limits of the Tien Shan ranges in central Tajikistan. The geographic boundaries of the survey have comprised 3 administrative districts of Khatlon (Farkhor, Hamadoni and Shurobod) on the Tajik side, 3 administrative districts of Kunduz Province (Qalai-Za;, Imam sahib, Dashti Archi) as well as 3 administrative districts of Takhar Province (Yangi Qala, Darqad, Chah Ab) on the Afghan side (see Fig. (837 ft) landslide dam on the Min River. First, they look at the Khait landslide (termed in the paper as a rockslide / loess flow), which is still clearly visible in the landscape, even on the low resolution Google Earth imagery available for this area: For the Khait landslide they conclude that the volume was probably rather lower than earlier estimates have suggested. The unchecked tourism in the region had promoted the rapid growth of hotels, roads, and shops throughout the region without paying heed to the environmental laws and demands of the ecosystem. It has been 11 days since the town of Oso, north of Seattle,. A marble statue of a woman with her head and hands lowered and .

It triggered hundreds of landslides throughout the epicentral area. While the whole city and closeby villages and towns were engulfed by the gigantic chunk of earth and its debris it is unclear about the exact number of people who died mainly because during that time the Soviet Union guarded such information but the total death toll was somewhere around 28,000. Numerous kishlaks in the Yasman River valley were overwhelmed by the loess flowslide that swept down the whole length of the valley. The lahars moved down the mountains with high velocity and swept away and drowned all that were unfortunate enough to be in its path. [3] There are no official contemporary records as information about major disasters was suppressed during Stalin's leadership. you are here The dam then overtopped, causing a flood and 2,500 deaths. The Khait or Hoit landslide occurred on July 10, 1949 in the Hoit district in the Gharm Oblast in the Tajikistan, then part of the Soviet Union.

This slide had multiple source areas on the southern side of the valley: They conclude that this is a rather destructive loess flow slide with a volume of about 245 million cubic metres. 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. The air bomb and the tidal wave took as many as 2,500 lives, wiping out the citys population plus also forcing the destruction of many more nearby towns and villages although the dam was pretty intact retaining two-thirds of the water after this misfortune. What happens to the Earth during a landslide? It is believed that floodwaters had no outlets this time, as most of the routes taken by the water previously were now blocked by sand and rocks. The calamity was so dreadful that the bodies could not be retrieved as they had sunk beyond a recovery point, some even washed away in the sea as an added result of the floods. However, landslide costs across the country are not currently tracked or measured in a uniform way by any one agency, so this figure is likely to be an underestimate. [1] It is also unclear whether these figures refer to all those killed as a result of the earthquake, or only those caused by the Khait landslide. This was catastrophic for those living below the dam. Mount Huascarn is a famous Peruvian mountain with a snowcapped peak that rises to a height of 22,205 feet. [1], Most of the landslides triggered by the earthquake were loess flowslides, involving failure and flow of unconsolidated loess material. A pyroclastic flow from the crater of the volcano had melted the glaciers in the mountain and sent deadly lahars, saturated with mud, ice, snow, and volcanic debris, rushing down the mountain at killer speeds towards the residential areas directly below it. Debris and mud flows are rivers of rock, earth and other debris saturated with water. Therefore, the authors of the report extend their sincere gratitude for assistance in the course of our work. The landslide around 200BC which formed Lake Waikaremoana on the North Island of New Zealand, where a large block of the Ngamoko Range slid and dammed a gorge of Waikaretaheke River between the Ngamoko and Panekiri ranges, forming a natural reservior up to 248 metres deep. .

Landslide attacks can damage enemies across the Rift Plane. The relevance of recent heavy rain and an almost synchronous seismic event are considered but it is concluded that the movement was the result of progressive failures and tectonic weakening while the landslide hazard was increased by the presence of rice paddy fields in the valley bottom. United States, 12201 Sunrise Valley Drive Reston, VA 20192, Region 2: South Atlantic-Gulf (Includes Puerto Rico and the U.S. Virgin Islands), Region 12: Pacific Islands (American Samoa, Hawaii, Guam, Commonwealth of the Northern Mariana Islands), Estimating the costs of landslide damage in the United States.

The paper re-evaluates the Khait landslide, and the other large slide that was triggered in the earthquake, providing a rational analysis of the likely impacts of the mass movements. This flow continued down the valley floor for more than another 4,000 m, despite the relatively low slope (3.6). For the Yasman Valley flowslide they estimate about 4,000 fatalities, and they determine that there were probably a further 2,400 deaths. The other landslide considered is a very large and complex flowslide that swept down the Yasman Valley, covering about 20 km.

The English (UK) government remove Scotland's massive wealth, revenues and resources and send some money back, about 60% of what is removed, as well as making cuts to welfare which is mainly a reserved power to the EngGov (UK) which means that the ScotGov also have to mitigate those (EngGov austerity) cuts to keep people from destitution. 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. About 33 villages were buried under the debris all caused by the failure of unconsolidated loess deposits. Adjusting these figures for the population of each area, the annual cost of damages per capita are $1.30 in the nine-county San Francisco Bay region; $2.50 in Allegheny County, Pa.; and $5.80 in Hamilton County, Ohio.
