The May 2006 Central Java earthquake (M<sub>w</sub>=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.
