Outline of Final Research Achievements

Persistent scatterer interferometry (PSInSAR) is a satellite-based method to estimate time-series surface displacement with high spatial density. During the series of researches, I revealed the complex surface displacement phenomena and underlying mechanism. Moreover, I developed a new algorithm that increase the estimation accuracy and spatial density of surface displacement.(1)We clarified estimation accuracy of surface displacement by PSInSAR analysis of Japanese SAR satellite, ALOS/PALSAR.(2)We developed a new computer algorithm that increase estimation accuracy and spatial density of surface displacement compared with conventional PSInSAR algorithm.(3)We revealed ground subsidence and uplift around large areas of the Kanto plain (100*100 km2), and clarified spatial distribution of surface displacement. We also revealed landslide displacement around the southwest side of Mt. Hakusan. Based on spatial distribution of surface displacement, we identified active landslide blocks.
