**2. Site Overview**

The Panjinbulake loess landslide is located in the Karayagaq Township, Yining County, Xinjiang. The coordinates of the central point of the landslide are 81◦30 32" E and 44◦11 48" N, 53 km from downtown Yining City, and 43 km from Sailimu Lake (Figure 1b).

Among the landslide geological hazards in the Piliqinghe basin, most are high speed and long runout loess landslides, which pose a huge hazard to local agricultural and livestock production. Among these landslides, the Kezileisai landslide buried 402 cattle and 5 sheep, and the direct economic losses reached 490,600 Yuan (¥). There were some similar landslides in the Piliqinghe Basin (Figure 2b). The Panjinbulake loess landslide is a typical high speed and long runout loess landslide that occurred recently in the region. Through analysis of the induced factors and dynamic effects of the landslide, this study provides a reference to the landslide dynamic hazards in the loess area.
