A strong earthquake hit El Salvador on January 13, 2001. The earthquake with a magnitude of 7.6 caused huge damage in the urbanized areas as well as numerous landslides. In case of these types of earthquake, the identification of hard hit areas is important and necessary information for decision-makers to handle the disaster relief process. In this study, remote sensing images taken before and after the earthquake by Landsat 7 (ETM+) satellite are compared to identify the location of landslides and hard hit urban areas. The proposed method uses the rationing between bands in the visible range as well as the sharpening of the multi-spectral bands by merging with the panchromatic band. It is expected that with the help of this additional band the identification of landslides and damaged areas will be improved.
