Abstract

The launch of the Advanced Land Observing Satellite 'Daichi' enabled us to detect the deformation of the land surfaces in detail with its high-resolution synthetic aperture radar sensor. We have observed a number of characteristic patterns reflecting the local surface deformation in an interferogram processed to detect the surface deformation triggered by the Noto Hanto Earthquake in 2007, which indicate the slight movements of landslides accompanied with the seismic motion. We processed an interferogram for Chuetsu-oki Earthquake in 2007 as well, and found several pattaerns suggesting the occurrences of subsidence and lateral flow of the soil. Thus, SAR interferograms can provide important information for monitoring of further development of deformation and planning of countermeasures.
