The Application of Interferometry SAR Data Analysis and Particle-based Simulation for Landslide Disaster Observation (Study Case in Kumamoto Prefecture)

摘要

Interferometry analysis of Synthetic Aperture Radar (InSAR) has been applied on ALOS PALSAR-2 data to observelandslide area in Kumamoto Prefecture, Japan. Field survey was carried out at study area on September 16-17, 2016 whichgathered correlation of interferometry image and displacement map retrieved from InSAR processing. 3D fluid simulation is usedto verify landslide pattern. This study shows good result in locating various scales of landslide area. Preliminary result ofparticle-based simulation shows correlation between flow and landslide pattern. This simulation analysis can be used to predictfuture landslide area.
