The Kahramanmaraş region in southeast Türkiye experienced two earthquakes, 7.7 Mw and 7.6 Mw, originating from the East Anatolian Fault Zone, where the African and Arabian tectonic plates shift. The Peak Ground Acceleration (PGA) observed in this region was 0.6 g, indicating strong ground shaking. Several studies were conducted on seismic impact, field-based structural damage, and geo-tectonics. This study applied remote sensing techniques to derive damaged buildings and validated them using updated Google Earth imagery data. The derived information can be used for inventory data preparation and as a fundamental basis for future susceptibility and hazard mapping. The damaged buildings were extracted using the Synthetic Aperture Radar (SAR) imagery (Sentinel-1) dataset. According to the obtained results, the city's area is classified into various categories of damage: 10% is categorized as very high, 15% as high, 35% as moderate, 38% as low, and 2% as very low. The city center is falling under a very high damage zone, possibly due to high-rise buildings and high building volume. The quality of the materials utilized is not examined in this study as a factor in understanding the percentage of damage. This study will lead to an understanding of the significant geospatial factors responsible for the building damage in Kahramanmaras City for future risk assessment. According to the discussion, the significant factors are building height, soil thickness, and slope, which add to the city's damage. This study offers a primary framework and approach to damage mapping for researchers, government agencies, and damage management practitioners.
