在青藏高原，活动性构造变形触发了频繁的地震，与活动断裂相关的巨型滑坡产生了严重的后果。对青藏高原乱石堡历史上一次长时间滑坡的特征和机理进行了研究，发现该滑坡最大滑动距离（L）为3.83km，高程落差（H）为820m。滑坡体体积（V）约为0.64-0.94 × 108m3，产生长径比（H/L = 0.21）。沿理塘-德乌左旋走滑断裂带的现代地表错动沿着穿过滑坡中段，并在断层上盘发生。地质填图、物探、探槽和14C测年等综合分析表明，滑坡发生在节理岩体中。1980 ± 30 YBP，可能由大地震触发。编制的体积和跳动距离数据，这个滑坡和其他先前公布的数据火山和非火山的长期运行滑坡产生一个复合的跳动长度-体积关系（L = 12.52V0.37），密切预测的LSB滑坡的跳动，虽然有很大的变化是在跳动长度的中心趋势。
In the Tibetan Plateau, active tectonic deformation triggers frequent earthquakes, and giant landslides associated with active faults produce serious consequences. A study of the characteristics and mechanism of a historical long-runout landslide in Luanshibao (LSB), Tibetan Plateau, China, finds a maximum sliding distance (L) of 3.83 km with an elevation drop (H) of 820 m. The landslide volume (V) was ~ 0.64–0.94 × 108m3, and it produced a long-runout (H/L= 0.21). Recent surface offset along the sinistral strike-slip Litang-Dewu fault passes through the middle part of the landslide, which initiated on the hanging wall of the fault. Geological mapping, geophysical prospecting, trenching, and14C dating together indicate that the LSB landslide occurred in jointed granite ca. 1980 ± 30 YBP, probably triggered by a large earthquake. Compilation of volume and runout distance data for this landslide and other previously published data for volcanic and nonvolcanic long-runout landslides yields a composite runout length-volume relation (L= 12.52V0.37) that closely predicts runout of the LSB landslide, although substantial variation is noted in runout length around the central tendency.
