Abstract
The authors propose a research framework in developing a method to search and detect the impact of catastrophic tsunami disaster by integrating remote sensing and GIS technologies, which consist of four damage mapping efforts, 1) Inundation mapping by satellite remote sensing, 2) Structural damage mapping by aerial photo interpretation, 3) Estimation of structural damage, 4) Mapping tsunami debris by post-event image analysis as an indicator of impact. The method is implemented to the 2011 Tohoku earthquake tsunami disaster to identify the regional impact of this event.
