The present invention relates to a method and system for analyzing volcanic activity, and a method for analyzing a volcanic activity of the present invention includes a radar satellite image processing step of generating an interference fringe from an image photographed by a radar satellite, A time series processing step of generating a mean map displacement map image in which an average surface displacement map of the surface of the volcano is displayed by performing a time series processing on the interference fringe, an image performing an operation of accumulating the average surface displacement map A stacking step and an interference pattern synthesized through the image stacking are analyzed to calculate a change amount of a position and a volume of a volcanic source in the average surface displacement map and reflect the position and volume of the changed source And an analysis step of generating an optimal model. According to the present invention, volcanic activity is analyzed using the InSAR technique and GIS information, so that it is possible to analyze and observe volcanic activity more easily and accurately.
