Abstract
About 70% coverage in Taiwan is mountain area. As Taiwan locates at the collision zone of Philippine seaplate and Eurasian plate, hazard induced by earthquake always happens. Also Pacific Ocean is nearby, thus tropical cyclone in summer can produce typhoon or heavy rainfall which induces high accumulated or high intensity rainfall in recent years. Despite of already slip landslide investigation, potential landslide is also very important for control priority of landslides. A heavy rainfall event in June, 2006 is selected in this research. Differential Interferogram Synthetic Radar (DInSAR) is adopted for search potential deformed landslides. Detail discussion of these potential deformed landslides and their relationship with following events is performed in this study. Moreover, ground landslide displacement monitoring results in three selected landslide sites selected to discuss the validity of this method and suggestion to further research.
