We tried to establish the detection methodology by viewing single high resolution synthetic aperture radar (SAR) satellite images which are now available. At first, a check list was made to qualitatively evaluate if it is or is not possible to detect landslide dams. By using that check list, high resolution SAR satellite images (TerraSAR-X, COSMO-SkyMed, RADARSAT-2) of Talas disaster in the Kii Peninsula have been evaluated. We confirmed conditions suitable for satellite as follows. All direction radar can detect landslide dams. The radar angle range suitable for obtaining images is from 35 to 50 degrees. Suitable image resolution is 3m. All sensors and bands are capable of detecting landslide dams.
