DEFORMATION ANALYSIS AND TRIAL STUDY FOR STRUCTURAL MONITORING USING C-BAND SAR IMAGING SATELLITE FOR 2016 KUMAMOTO EARTHQUAKE

Abstract

 Deformation analysis and trial study for structural monitoring using C-band synthetic aperture radar (SAR) on Sentinel-1 satellite for Kumamoto Earthquake is described. C-band SAR data is expected to excel at distance (phase) resolution to conventional L-band SAR data. Major ground surface displacement before/after Kumamoto Earthquake is confirmed by interferometric SAR (In-SAR) analysis. Also, sever structural deformation is detected from reflected intensity image. However, small structural movement is not able to evaluated due to the limitation of ground resolution.
