2003年12月26日，伊朗东南部巴姆市发生强烈地震。地震给这个城市及其周围的农村地区带来了巨大的破坏。QuickBird是一颗高分辨率卫星，于2004年1月3日，即事件发生8天后，拍摄到了巴姆的清晰图像。2003年9月30日，也就是事件发生前三个月，QuickBird也观测到了这座城市。本文利用事件发生前的影像，在地理信息系统上登记各个建筑物的位置，并分配主要道路所包围的城市街区。然后，基于欧洲宏观地震等级（EMS-98）的视觉损害解释进行了逐栋建筑物，比较事件前后的图像。将损伤检测结果与现场调查数据进行了比较，证明了高分辨率卫星图像在损伤检测中的准确性和实用性。
A strong earthquake struck the city of Bam in southeast Iran on 26 December 2003. The earthquake brought massive destruction to the city and its surrounding rural areas. QuickBird, a high-resolution satellite, captured a clear image of Bam on 03 January 2004, eight days after the event. The city was also observed by QuickBird on 30 September 2003, about three months before the event. In this paper, using the pre-event image, the location of individual buildings was registered on GIS and the city blocks surrounded by major roads were assigned. Then, the visual damage interpretation based on the European Macroseismic Scale (EMS-98) was carried out building by building, comparing the pre-event and post-event images. The result of the damage inspection was compared with field survey data, and the accuracy and usefulness of the high-resolution satellite images in damage detection was demonstrated.
