In this study, changes of the L-band ALOS/PALSAR polarimetric signal scattered from earthquake/tsunami damaged areas has been investigated. Because it is not always possible to get data sets which have sufficiently good spatial/temporal resolutions to detect large area of damages precisely, it is of specific interest to use of wave polarization information appropriate to assess disaster-induced changes of scattering phenomena. This study aims to evaluate the fully polarimetric change detection method for automatic identification of damages. Preliminary experimental results indicate that a high potential of utilizing fully polarimetric measurements for identifying damaged area. The polarimetric parameter on the volume scattering contribution among backscatter signal can provide useful information on the spatial extent of collapsed building.
