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. Undertaking of survey has allowed mapping of surfaces of natural hazards evolution and doing a holistic assessment on a full spectrum of hazardous natural processes in the target district area of which roughly 2267 km2 (21%) belong to extremely hazardous category, 7432 km2 (69%) to highly hazardous and 1000 km2 (9,3%) to moderately hazardous. It had a magnitude of 7.5 and triggered a series of landslides that together led to 7,200 deaths.

It ended up carrying 50-100 million cubic meters of water, mud, and rocks, which reached the village of Yungay and smothered all life forms therein under its deadly cover. [3], In the area of maximum felt intensity (>IX) most kishlaks were completely destroyed. Heavy rainfall had been previously recorded in the region which had also led to flash floods, but the devastation produced in 2013 was comparable to no earlier data. 1933. The main shock had a magnitude of 7.4 calculated as the 'unified magnitude' using the 'Soviet Method'. 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.

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. Khait Landslide, Tajikstan, July 1949 (4,000 deaths)) 8. 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. 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.
