Earthquake-induced landslide dam in the Kashmir Himalayas

The Kashmir earthquake of 2005 triggered numerous landslides in inaccessible areas of the western Himalayas, which could be mapped using satellite remote sensing. The largest recorded seismicity-induced landslide dammed a river, which resulted in the formation of a stream in the toe region and creat...

Description
Summary:The Kashmir earthquake of 2005 triggered numerous landslides in inaccessible areas of the western Himalayas, which could be mapped using satellite remote sensing. The largest recorded seismicity-induced landslide dammed a river, which resulted in the formation of a stream in the toe region and created two reservoirs that pose an enormous threat in the event of a landslide dam breach. Using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data sets corresponding to the pre- and post-earthquake period and derived digital elevation models, landslide-induced lakes were monitored. The aerial extent, depth profile and volume of both the reservoirs were determined. This study has demonstrated the utility of ASTER data in providing valuable information that is critical for hazard mitigation in case of a landslide dam breach.
