| Abstract: | Taking a county in Henan province as an example,this paper analyzed the high resolution remote sensing image,got the buiding information successfully,built the damage matrix and assessed the seismic ability under frequent and rare earthquake with comprehensive earthquake risk index.Contracted with the filed survey,the HRRSI method has high precession with low error,which can meet the practical application satisfyingly.The result shows that HRRSI is extremely helpful and promising in the earthquake damage prediction. |
