Active landslides in the Rogun Catchment, Tajikistan, and their river damming hazard potential

Abstract The region of Tajikistan where the Rogun Hydropower Project is currently under construction has experienced large and catastrophic slope failures in past, often triggered by earthquakes. Co-seismic are thus common pose a high hazard potential; however, to date, no specific analysis activity this area been presented international journals. Here, we present an inventory active landslides identified through satellite imagery particular exploiting space-borne differential radar interferometry. Surface displacements provide basis for detection instabilities, which then further classified using geomorphological indicators visible optical imagery. Additionally, proximity tectonic lineaments, as well regional seismicity, analysed investigate potential relationships integrated river damming potential. results show that approximately 31% all detected would have upon failure, highlighting importance such phenomena efficient long-term land use planning management hydropower plants.
