In this paper, the authors developed the methodology of vegetation cover ratios using multiple types of optical sensor data and clarified microwave backscattering characteristics on vegetation and environments acquired by Synthetic Aperture Radar (SAR). These data are used to analyze the effects of eruption from Mt. Pinatubo, the Philippines over a time period from 1991 (eruption time) to present (1997). By this satellite image analysis, chronological changes from vegetation damage in the term of decrease rate of vegetation cover caused by volcanic ash fall and suffered area by mudflows. Through satellite image analysis, changes in vegetation damage over time is assessed from the decrease in vegetation cover to volcanic ash and mudflows.
