Abstract
The devastating earthquake (Ms=8.0) of 12 May 2008 in Sichuan, China struck the whole world. To detect the large damaged area in less time and identify seismogenic structure, remote sensing technology is strongly recommended. This paper attempts to focus on seismic area to analyze the earthquake damage from different aspects. Firstly, pre- and post-earthquake Landsat TM/ETM images, CBERS-02B CCD images, DEM and relating data is used to observe ground changes. The analysis assumption is testified by the Tangjia Mountain dammed lake in Beichuan county and landslide in Anxian county in relative news and reports. Furthermore, Radarsat data is used to complement the analysis, since it could provide the seismic area surface deformation and a better 3-D vision. Also specific information of local fault, landslide and sub-block features in seismic area could be observed and got, which helps to perfect the damage analysis. All these analysis results could be useful for improving and revising the interpretations of geological, geodetic and seismological data. Finally, the possibility of estimating and inducing earthquake damage using remote sensing data is discussed.
