Abstract:
|
The fast developing remote sensing techniques play an increasingly important role in earthquake emergency response , disaster survey and loss estimation. As there is a lack of quantitative studies on seismic damage based on remote sensing , its practicality in seismic disaster management has usually been questioned. The paper introduces the essential quantitative study
idea , the concept of the remote sensing seismic damage index ( DRSI ) and analysis models ,demonstrates the seismic damage indices ( DGI ) of buildings obtained from ground surveying and its quantitative relation to DRS I in Dujiangyan city , Sichuan Province , which was destroyed by the 2008 Wenchuan earthquake with MS810. The primary results show that an obvious relationship exists between the DRS I of buildings obtained from the high resolution satellite or aerial remote sensing images and DG I or the building collapse ratio obtained through ground survey , which suggests that the quantitative study on seismic damage based on remote sensing will provide an effective method for seismic damage survey and loss estimation. |
