Study On A Modified Assessment Of Seismic Intensity Based On Both Muilti-Source Rs Images And Spatial Grid Analysis |
Abstract | ||
|---|---|---|
The seismic damage index (DI) has been developed to be calculated based on the damage interpretation of buildings et al from remote sensing, and further converted to the seismic intensity, but the statistical unit (usually a village or street block) for DI is pre-required. This will affect the timeliness in the emergency stage. The other case is that different capability exist in building damage extraction from multi-source RS images. So it must first convert the DIs evaluated from various images into comparable DIs. The authors in this paper propose an improved method of DI assessment of seismic damage and intensity in gridding unit with multi-source images, and then build new conversion equations according to building damage by both the extraction from aerial RS images and field survey in the disaster region of 2003 Ms7.0 Lushan earthquake. The validation check of the equivalent DIs show high consistency with the ground truth, which implicate that the method and empirical DI conversion models proposed in the paper is applicable in earthquake emergency stage. |
