The May 2006 Central Java earthquake (M_w=6,3) heavily struck the Special Province of Yogyakarta, Indonesia. The widespread damage and high number of casualties revealed the necessity of vulnerability assessment within this region. A vulnerability and risk analysis was conducted using a GIS-based Indicator-Index Method. In this analysis very high resolution satellite images were used for two purposes: Firstly to validate the risk map by detecting damaged areas. This lead to the development of an object-based and a pixel-based methodology for damage detection. The detected damage areas were analyzed on a building unit scale. For each building unit the damage was calculated. Secondly to extract detailed information on the spatial distribution of landuse in the study area. This was conducted using a object-based, multiresolution approach.
