Abstract
A large-scale eruption occurred in Kagoshima, Kuchienorabu Island on May 29, 2015. This eruption released pyroclastic flow, which reached the shore areas. In this study, the disaster caused by this eruption was investigated using near real-time multi-spectral satellite images from Landsat-8/OLI, observed before and after the eruption, and ASTER/Global DEM data. These data were used for detailed image interpretation and three-dimensional indications of the extent of damage and the area covered by the pyroclastic flow. Furthermore, the characteristics of the distribution of damaged forest areas were obtained through NDVI analysis. From these investigations, the effectiveness of information from the near real-time remote sensing data in the evaluation of the volcanic disaster was assessed.
