BY : EDY IRWANSYAH
The impact assessment of Sumatera earthquake 2004 estimated that around 19 percent of the approximately 820,000 building units in the affected district suffered around 50 percent damage while nearly 14 percent were totally destroyed. This GIS based assessment has been carried out using a combination of data extracted from high resolution IKONOS images, aerial photographs and substaitiated through field surveys as well as the data collected from various institutions.
Building damage in Banda Aceh City (BAC) has been classified in five class and continue re- classification with visual image interpretation based on European Microseismic Scale (EMS) classification. From the total 27,796 building units in BAC, 35 percent are classified as totally destruction, 29 percent on slightly till moderate damage condition and 36 percent just flooded upon tsunami.
Calculation cost of damage in this study was conducted using building size classification standard in which has been used by BPS for socio-economic survey. Total cost of building damage as impact of earthquake (and tsunami) in BAC is similar with $193,564,333.
