Information Model has the features of easily using and strong scientific. It's widely used in early warning of geological disasters. Based on the summarizes of the application of the information model used by others, this paper did some expansion of the model. This paper introduces dynamic spatial data to the information model, which makes the scope of applications of information model further expand and it will meet the needs of dynamic monitoring of geological disasters. Taking the Early warning of geological disasters in Fuling District as the study case, it demonstrates the feasibility of the expansion.
