Abstract :
The area of Southwestern Ryukyu Arc and Eastern Taiwan are characterized by collision and subduction of the Philippine Sea Plate under the Eurasian Plate. Huatung Valley is a huge valley formed by plate motion and existing between the cities of Hualian and Taitung with approx. length of 130 km. Since 1998, Tokai University has started seismological activity measurements with Dahan institute of technology (DIT). DIT measuring GPS and electronic distance meter (EDM) data to monitor the crustal movement in the northern part of test area. We have performed a repeat-pass differential interferometric analysis using the ENVISAT/ASAR data in 2005 and 2006. In addition, we propose a crustal movement extraction using successful ALOS/PALSAR image pairs in 2007.
