Sudden landslides cause big problems all over the world. These landslides often take place in the fault areas marked by a high seismic activity. Here, we study the impact of teleseismic events, located in the Pamir-Hindukush source zone, on the stability of the landslide-prone slopes in Tien-Shan. The Pamir-Hindukush zone is a unique seismic region of the Earth, where the strongest earthquakes occur at depths of 200–250 km. Some of those earthquakes have a magnitude of M > 7. Overall, 89 perceptible earthquakes (M > 5) occurred from 1991 to 2010 (according to the available data) with 35% of them occurring in springtime. In the mountainous regions of the Tien-Shan, such earthquakes cause liquefaction on water saturated slopes with accompanying slumping and cracking. This paper describes mechanisms of sudden landslide movement using the example of Sary-Bulak landslide which failed in 1976 after the earthquake in the Pamir-Hindukush zone.
