Establishment of monitoring and hazard level assessment system for landslide disasters by ALOS, and its application

Landslide disaster is one of major disaster in whole world. In case of Japan, over 1 million sites of landslide are distributing in wide area. Therefore, it is very difficult to monitor all landslides and evaluate its hazard level. To develop the landslide monitoring system that can monitor large area is important because landslide disaster is increasing year by year especially in Asian region. In the research, we'll develop the prototype of large area landslide monitoring system using ALOS data at a few test sites at Japan. Analytical results of ALOS data will organize by landslide monitoring system that developed by GIS. On the GIS, it is possible to simulate the landslide hazard level by numerical model, and also analyze the movement history of the landslide. Now we are developing this system at one test site of Gifu, Japan. And PALSAR DInSAR analysis is applied to a few test sites in Japan.
