摘要

The occurrence of a tsunami, a set of oceans waves caused by any large, abrupt disturbance of the sea surface, hitting avulnerable system on land can cause massive loss of life, destruction of coastal infrastructure and disruption of economicactivity. Vulnerability assessment and risk modelling are important components for an effective end-to-end hazard earlywarning system and therefore contribute significantly to disaster risk reduction. The focus of this study is on thecapabilities and synergistic usage of multisensoral remotely sensed data to contribute to these complex tasks. We usemedium and high resolution optical satellite data (Landsat and Ikonos), high resolution radar data from TerraSAR-X aswell as a digital elevation model to provide multiple products for the assessment of spatial vulnerability in case of atsunami impact on the heterogeneous and highly structured coastal urban area of Padang, Indonesia. Results includephysical indicators like dimension and location of urbanization, quantification of potentially affected buildings, theidentification of safe areas as well as a time-dependent population assessment.
