Type of Geohazard Incident: Massive landslide in So.Tagaytay and So. By looking at contempory reports of the population of the Khait area and census data on settlement size and population density they reject earlier estimates of the loss of life. The landslide near the rural community of Manti, Utah, caused an expenditure of about $1,800,000 or about $1,000 per person during the period 1974-76. The Khait or Hoit landslide occurred on July 10, 1949 in the Hoit district in the Gharm Oblast in the Tajik Soviet Socialist Republic, then part of the Soviet Union. [1], The earthquake occurred at 09:45 local time on 10 July 1949. It had an estimated magnitude of 7.5 '"`UNIQ--templatestyles-00000002-QINU`"'Mw. It had a magnitude of 7.5 and triggered a series of landslides that together led to 7,200 deaths. A re-examination of the mechanism and human impact of catastrophic mass flows originating on Nevado Huascarn, Cordillera Blanca, Peru in 1962 and 1970 Engineering Geology, 108 (1-2), 96-118 DOI: 10.1016/j.enggeo.2009.06.020, Posted in: A dormant stratovolcano suddenly erupted destroying many towns and villages. and P.E. The avalanche travelled a distance of 16.5 kilometers. They develop during intense rainfall, runoff, or rapid snowmelt, changing the earth into a flowing river of mud or slurry .. Uncategorized It is difficult to estimate the monetary costs of landslides because they can include both direct and indirect costs. 3 What main factors cause landslides and floods? 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. 10. Required fields are marked *. Tumbling down at terribly swift speeds of twenty feet per second they caused havoc in the residential areas below. 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. The average cost of a water damage or freezing claim is $11,098. Share sensitive information only on official, secure websites. In the Yasman valley hundreds of loess Acknowledgements Killing an enemy with this ability is counted as a Melee Kill. Huaraz Debris Flows, Ancash, Peru, December 1941 (5,000 deaths), 6. More than the usual rainfall that year made it worse. These primary hazards often produce secondary hazards such as ruptured utility lines, hazardous spills, and fires. What causes them? Reports suggest a loss of about 10% of the Vargas population. Remarkably it travelled over a slope with an angle of just two degrees! One of the worst natural disasters in the history of India occurred in June of 2013, when powerful flash floods killed around 5,700 people in the Himalayan state of Uttarakhand. (2009 in press). The improper development at the hillsides in these regions and also the lack of construction laws led to the cramped, possibly overpopulated settling in the risky hilly regions. When newly built in 1963, the Vajont Dam in Italy was the tallest in the world but building the dam proved fatal as it activated strong seismic activity.

The rock mass began to travel to the northwest as a rockslide into the Obi-Khaus-Dara valley. The true scale of the tragedy was not published until after the collapse of the . 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. Estimates based on likely population densities in the two settlements that suffered the most damage, Khait and Khisorak, suggest that only about 800 people are likely to have died directly as a result of the landslide. A recent estimate of the total annual cost of landslide damage is in excess of $1 billion {Schuster, 1978}. Yungay Landslide. To date however, it has been difficult to quantify the cost of landslide damage because of the variety and The flow broadened as it reached the main Obi-Kabud River valley, sweeping through part of Khait, crossing the river, before climbing a 25 m high terrace on the river's western bank and continuing a further 700 m, overwhelming the village of Khisorak. Social agitators claim that many people lost their lives mainly because the area did not have strict rules on the construction of homes, which allowed people to build homes on unstable ground.

In July 1949, the M7.4 Khait Received 6 September 2008 earthquake triggered many hundreds of landslides in a mountainous region near the southern limit of the The landslide was triggered by the 1949 Khait earthquake and buried 33 villages and has by some estimates killed 28,000 people. 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. The term landslide actually has two meanings. The natural calamity which struck the rural district of Haiyuan on the evening of December 16, 1920 claimed over 100,000 lives, and severely damaged an area of approximately 20,000 square kilometers. Almost half of the U.S. states are at risk for earthquake damage. For centuries, the mountainous belt running through Central Asia has witnessed a large number of disasters involving earthquake-triggered landslides. 800 people lost their lives when . [2], The total distance travelled by the flowslide is 7.4 km. 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. This landslide triggered a gigantic tsunami in which a tremendous amount of water overpowered the dam in an 820 feet wave devouring and destroying the Piave Valley below with the terrible flooding. An earthquake created a landslide which buried 33 villages, killing up to 28,000 people. Photo credit: FEMA News. Site. Kelud Lahars, East Java, Indonesia, May 1919 (5,000+ deaths), 5. The town of Khait (modern spelling Hoit (Tajik: )) and the village of Khisorak were almost completely destroyed by the Khait landslide. The Regional Director . The gravitational pull that facilitates a collective movement of soil, rock, and debris down a steep slope is called a landslide. [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. . These landslides. 1988, resulted in approximately $12 million in damage and cost $8 million to rebuild. A marble statue of a woman with her head and hands lowered and an expression of grief was later erected at the site. This slide was reported to have travelled 12 km. ADVERTISEMENT. The landslide was triggered by the 1949 Khait earthquake and buried 33 villages and has by some estimates killed 28,000 people. The old town of Diexi suffered the worst fate of all as it sank into the landslide-created dam below. Of the 8 th International Conf. In general, goals and objectives of surveys were received well by our partners. This landslide was one of the most destructive landslides in history. As a result of work performed, we have highlighted, described and assessed the following natural hazards: earthquakes, floods, landslides, mudflows, river and ravine erosion, suffusion, karst and subsidence. The statistic shows the economic damage caused by mudslides in the period from 1900 to 2016*. Landslide damages are one of the most costly natural disasters in the United States. Moving downhill with high velocity, these killer lahars swallowed all that came their way. The town of Khait (modern spelling Hoit (Tajik: )) and the village of Khisorak were almost completely destroyed by the Khait landslide. 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. This released large volumes of water, itself laden with mud, rock, and ice, into the valley below with an unimaginably high force. In January of 1962, a thaw triggered the breaking off of a portion of the north summit of the mountain, leading to a landslide/avalanche that led to the tragic death of nearly 4,500 people. Can be cast while in mid-air. Official websites use .gov For the Yasman Valley flowslide they estimate about 4,000 fatalities, and they determine that there were probably a further 2,400 deaths. The consequences were disastrous with the forming of an inland tidal wave, the force of the fall was so terrible that the atomic bomb type of powerful gust of air crushed the city of Longarone with only 30 children managing to survive. Wesson (USGS) Licensing . . 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. Some reports, such as the Wikipedia article on this landslide, have suggested a death toll as high as 28,000 people, although to be fair this may well be something of a misinterpretation of the original source. Some single landslide events have killed numbers in excess of the populations of small countries. Landslides cause property damage, injury, and death and adversely affect a variety of resources. Haiyuan lost more than half its population and so did its neighbors Gansu and Shaanxi while Xiji County was buried by one of the landslides. Numerous kishlaks in the Yasman River valley were overwhelmed by the loess flowslide that swept down the whole length of the valley.

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. Haiyuan County alone lost more than 50% of its population in the disaster. The estimated volume for this landslide is about 75 MCM. The average cost for earthquake insurance is between $100 and $300 per year. In a typical year in the United States, expansive soils cause damage to more homes than earthquakes, floods, hurricanes, and tornadoes combined. Losses from landslides in the United States were estimated in 1980 to exceed $1 billion per year. 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.
