| Research Abstract |
This study proposes a method to search and detect the impact of tsunami disaster by integrating numerical modeling, remote sensing and GIS technologies, which consist of four damage mapping efforts, 1)Regional hazard/damage mapping effort to search the potential impacted region, 2)Damage estimation effort using the numerical modeling of tsunami inundation and fragility function for structural damage, 3)Local damage mapping effort using the analysis of high-resolution optical satellite imagery to detect the extent of tsunami inundation zone and the structural damage. The method is implemented to the recent tsunami events to identify the structural damage probabilities within the inundation zone, combined with the post-tsunami survey data.
