The weather is subtropics that speeds up the surface of rock weathered and eroded, and also hides many potential disasters. Hence, a regional slope stability assessment has significantly essential value for project planning and slope precaution. The research has analyzed possibility of regional potential landslide and evaluated potential factors that may cause slope failure. The research has used slope stability analysis to analyze seismic loading and groundwater level for possibility of slope failure, to understand slope region where is affected by the function of dynamics and failure, to apply finite element method of PLAXIS software and analyze the result after movement, to discuss the change of displacement for each of acceleration historical graph and groundwater level, and to provide slope precaution and prevention for reaction function and propose seismic design as reference. The result of the research has shown that the displacement of geological section will follow seismic loading due to the different data that means the soil distribution of slope has quite affected regional slope stability. To compare with the displacement of EW and NS direction of observation, the reaction of displacement TAP045EW observation of EW direction is rather larger than that of NS direction. In general, the amount of displacement of EW and NS direction intends the same that towards the entire of movement, and the direction towards to slope that produce sliding movement. The displacement of majority observation is similar to TAP045EW and TAP045NS reaction. Among the displacement of TAP045EW without groundwater and other observation is different from the top of slope protrusion. Basically, the graphs of displacement have shown that major sliding direction towards the outside of slope. In addition, due to uncertain soil properties and parameters, the data of displacement reaction may be little smaller. However, it can be discussed soil layers parameters of the region for simulation in the future.
