Based on the digital landslide technology, the authors employed revised 10 high-resolution remote sensing images between 2002 and 2016 as remote sensing image information source, densified ASTER DEM data as landslide elevation information source, and 1:200 000 Luoyang City regional geological maps as the geological environment source and, in combination with Dongmiaojia landslide, analyzed the creation conditions and active characteristics of the landslide, and predicted the present stability situation of landslide. The result shows that the active process of Dongmiaojia landslide can be divided into four stages, i.e., the first landslide activity, the subsequent traction activity, the front landslide activity and the follow-up activity, which formed topography of four level terraces with seven platforms and the front steep slope. The estimation of the total size of the Dongmiaojia landslide is 425.4×10 ⁴ m ³. The comparison of ten high-resolution images indicates that there has been no obvious deformation and displacement in the Dongmiaojia landslide in recent years.
