In October 2015, Typhoon 201523 created very strong winds in central Hokkaido, Japan, causing windfall forest damage in Hokkaido prefectural forests. To assess the windfall damage quickly, we applied remote-sensing techniques using LANDSAT8 images (resolution 30 m) to estimate the distribution and area of the windfall damage and gave the results to relevant organizations. We could evaluate large-scale (≥1 ha) windfall damage, and we found that the LANDSAT8 analysis results helped to reduce the effort required in field surveys.
