Before landslide happen, there will be changed in internal stratigraphic that cause self-potential changing and generate seismic signal. Therefore, this study in order to verify the situation, and indoor slope model test conducted landslide test, and use control factor of rising groundwater and rainfall to observe self-potential changing and seismic signal during the test. The research results showed self-potential can reaction groundwater flow. In a continuous landslide process, it may correspond with the self-potential and seismic signal on the process. The research goal is determined whether the signals can be applied landslide warning before it destroyed, or it creates a new way to measure. It provides a new way for landslide monitoring and early warning.
