Abstract： Loess landslide is one of the most severe geological disasters in northwest China. It not only does great harm to people's life and property， but also restricts of social and economic development. In order to find out the geological characteristics of Wangjiapo landslide in Baqiao District of Xi'an City， this study used micromotion detection method. The ground distribution， slide surface location and structural development characteristics of the landslide were ascertained by means of field data acquisition， indoor data processing and spatial autocorrelation（SP AC） method and result interpretation. Additionally， by combining drilling data， it is demonstrated that the micromotion detection method yields accurate and reliable results at a low cost for landslide exploration. The engineering example shows that micromotion detection technology can provide certain technical support for disaster prevention and reduction， which is a very promising engineering geophysical exploration method.
