Abstract

Indonesia is characterized by a very high level of natural hazards such as seismic and volcanic activities and it is one of the main tsunami-prone areas. Natural hazards (earthquakes, flooding, volcanism, etc.) determine life conditions of the population to a large extent: several active volcanoes have the potential to seriously threaten adjacent communities. Extended flooding has led to severe problems. Therefore, various types of vulnerability assessment methodologies, software, and tools available for the state, local governments, and local stake holders have to be investigated. In the fields of awareness, preparedness, and mitigation of natural hazards, a multidisciplinary integration of different methods and data has the greatest potential for substantial progress. In the scope of this study, the use of remote sensing and geographic information systems (GIS) is examined as contribution to a multirisk database. Satellite imageries and digital elevation data form the basic data stock. Digital image processing methods are used to enhance satellite data in order to contribute to the investigation of environmental conditions and of natural hazards. LANDSAT enhanced thematic mapper (ETM) imageries merged with digitally processed digital elevation data clearly indicate areas that might be prone to flooding in cases of extreme weather events, catastrophic tsunamis, or storm surge. Subsurface structures such as fault zones can be derived by geomorphologic analysis (drainage pattern) and the identification of linear tonal anomalies on the imageries. Some factors influencing volcanic activity can be derived from satellite imageries and morphometric maps such as slope steepness.
