Abstract

In 2011 a 9.0 magnitude earthquake occurred off the pacific coast of Tohoku area of Japan. Accompanied with the subsequent tsunami, it caused serious damages on buildings, infrastructures and so on, in the coast area. We made observations of the damaged areas by the NICT airborne X-band synthetic aperture radar (SAR) system, “Pi-SAR2”, immediately after the earthquake. Pi-SAR2 can produce fully polarimetric radar images with high spatial resolution of 0.3 m. The image data were used to estimate the damages in detail and quantitatively. We have found that the high resolution radar image data are useful to estimate damaged buildings, flooded areas and amount of debris. Multitemporal observations are essential to reveal those changes.
