【 摘 要 】

The seismic performance assessment of building community prior to the occurrence of earthquakes is important to the disaster prevention and relief planning. However, one big challenge is the available information for assessment is generally limited, which makes the reliability of the assessment low. In this paper, a new approach to extraction and analysis of high-resolution remote sensing images is proposed to facilitate its prior seismic performance assessment. The proposed approach is finally verified by the case study of Dujiangyan urban area in Wenchuan earthquake. In the case study, the performance of the buildings during the earthquake were extracted from the aftershock remote sensing images by the application of the image change detection technology, and it is compared with the results from the prior assessment with the proposed approach. The comparison shows that the consistency is well between the prior assessment and the aftershock investigation.
