Аннотация:The Tien Shan is an intracontinental mountain system~1500 km long and up to 500 km wide that formed between theTarim Basin and the Kazakh Shield due to the India-Asian collision.It is shared by the five nations of Kyrgyzstan, Kazakhstan, Uzbekistan,Tajikistan, and China. As one of the highest and most seismotectonicallyactive parts of the Central Asian Mountain Belt, it is extremelyprone to large rock-slope failures. At least nine rock slopefailures >1 km3 in volume, two of which involved ~10 km3, have beenidentified in the Tien Shan. Thanks to an arid climate many of theseformerly river-blocking rockslides and long-runout rock avalanchesare well preserved, and both their morphology and internal structuremay be readily studied in detail. Here we briefly describe thestate-of-the-art and planned future international collaborations inresearch on rock-slope failures in the Tien Shan.
