Abstract: A large landslide occurred in the township of Wuyang, Zhenyuan County, Guizhou Province. This paper presents the regional geological environment conditions, topography, tectonic geology, hydrogeology, engineering influence and other factors that might induce the geological hazards such as landslides. Further, the triggering factors of the landslide are summarized. A simplified geological hazard early warning and forecast system was established in the field. Based on the site investigation results, supporting measures that are safe, reliable, cost effective, environmentally friendly and vegetation measures are recommended.

Key words: Landslides, Geological Hazards Landslide Analysis, Early Warning System, Support Measures
