There are many active volcanoes and active faults over Kyushu, which is the southwest island in Japan. Kyusyu
area has the stress field, which tends to develop the normal faults. These crustal features are different from those
of other region in Japan. Additionally, the natural hazards accompanied with geomorphic changes like landslides
and debris flows occur at many places in Kyushu region. In order to learn the critical tendency of the crustal
deformations in Kyushu, it is needed to investigate the amount of the geomorphic changes all over this area
widely.
The DInSAR is the powerful technique to measure the geomorphic changes at a time. Usually the target of
DinSAR measurement is the local crustal movement in one scene, but the area of one scene is too narrow for
covering all Kyushu island area. This study discusses the detection of the wide-area crustal movement in Kyushu
area by DInSAR using JERS-1/SAR and ALOS/PALSAR data. The differential interferograms in 5 paths around
Kyushu main land could be connected with the short-interval data pairs.
