The Huascarn earthquake set the ticking time bomb for a number of seismic events that plunged the village into ruins. [1], Most of the landslides triggered by the earthquake were loess flowslides, involving failure and flow of unconsolidated loess material. If the costs were available for the damages from landslides in Los Angeles in 1977-78 and 1979-80, the annual per capita costs probably would be much larger. In July 1949, the M7.4 Khait earthquake triggered hundreds of landslides in a mountainous region near the southern limit of the Tien Shan, central Tajikistan. Remarkably it travelled over a slope with an angle of just two degrees! Those past landslides reshape the slope, making it. Numerous kishlaks in the Yasman River valley were overwhelmed by the loess flowslide that swept down the whole length of the valley.
