Japan Aerospace Exploration Agency (JAXA) detected the landslide area of the Izu-Ohshima Island by a polarimetric time-series analysis of the polarimetric Interferometric airborne L-band SAR data. This island was attacked by the Typhoon No. 26 on Oct. 16 and severely damaged by the long lasting heavy precipitations. Western center part of the island was severely landslide. JAXA flew the Pi-SAR-L2 on Oct. 22 over the island and also retrieved the Pi-SAR-L data of Aug. 30 2000 from the data archive. The correlation coefficient of the HH-VV polarization data and its time-variation over 2013 and 2000 successfully discriminated the landslide area as the surface scattering from the forested areas as the volume scattering area. In this short paper, we describe the Pi-SAR-L2 observation and its analysis.
