英文摘要	This paper investigates the setting, causes, and main dynamic characteristics of the landslide that occurred at Xinmo village, Diexi, Sichuan province, China, on June 24, 2017. By comparing the pre- and post-sliding DEMs, the landslide involved the failure of approximate to 3.0 x 10(6) m(3) rock mass from its source area, and had a final volume of approximate to 6.3 x 10(6) m(3). The landslide runout extended 2800 m horizontally and 1200 m vertically, and covered an area of approximate to 143.1 x 10(4) m(2). Field investigation indicates that entrainment was one of the major causes of the increase in volume of landslide. To reproduce the behavior of the landslide runout, a depth-averaged continuum model that takes entrainment into consideration is applied. The simulated results generally agree well with the characteristics of the sliding path and distribution of the landslide deposit as observed in the field. It is demonstrated that entrainment plays a significant role in landslide mobility and volume. The final volume of the landslide is calculated about 6.21 x 10(6) m(3), which has more than double its initial volume.
