Abstract. Located in a mountain area of Southeast Brazil, the municipality of Campos do Jordao has been hit by several landslides in recent history. Among those events, the landslides of early 2000 were significant for the number of deaths (10), the population affected and the destruction of infrastructure that caused. The purpose of this study is to assess the relative contribution of natural and human factors in triggering the landslides of the 2000 event. To achieve this goal, a detailed geotechnical survey was conducted in three representative slopes of the area to obtain geotechnical parameters needed for slope stability analysis. Then, a set of numerical experiment with Geo-Slope software was designed including natural and anthropic factors separately. Results showed that natural factors, thus is, high intensity rainfall and geotechnical conditions, were not severe enough to trigger landslides in the study area and that human disturbance were entirely responsible for the landslides events of 2000. Since the anthropic effects used in the simulations are typical of Brazilian hazardous urban areas, we concluded that the implementation of public policies that constrain the occupation of landslide susceptible areas are urgently needed
