[MIS34-P37] DInSAR Analysis on regional distribution pattern of surface displacement caused by the 2016 Kumamoto Earthquake
Keywords:Satellite SAR Differential Interferometry (DInSAR), Sentinel-1 C-SAR data, regional distribution pattern of surface displacement
Two co-seismic pairs of the Sentinel-1 C-SAR data, acquired on 2016/4/8 and 2016/4/20 on the ascending orbit and of 2016/3/27 and 2016/4/20 on the descending orbit, are used in the study. The results of DInSAR analysis of each pair as well as 2.5-dimensional analysis combining these pairs are introduced. Adding to the Sentinel-1 C-SAR data processing, Multi Aperture Interferometry processing which treats the azimuthal offsets along the flight direction of the satellite was performed using co-seismic pair of ALOS-2 PALSAR-2 data covering the main part of the Futagawa Fault and the Mt. Aso caldera.
