Estimating landslide dynamics is vital for the prevention of disasters. Differential interferometric synthetic aperture radar (DInSAR) based on L-band SAR satellites an effective tool estimating forested landslides that occur in Japan. High-temporal observations have been planned future. Thus, it necessary to further investigate specific advantages high-temporal dynamics. In this study, we used DInSAR data with different time windows identify active Hokkaido, This study first attempt demonstrate We successfully observed two landslides, Kounai-1 and Kounai-2, using over a window 14 days. present spatial observation Kounai-2. addition, discuss Kounai-2 interferograms, our results suggest both are subunits same landslide, called Kounai landslide. These indicate can mitigate cycle slips enable estimation
