Abstract
Sudden landslides formed simultaneously in different areas, triggered by single source seismic impacts of Pamir-Hindu Kush earthquakes create great danger in the foothill areas of the Central Asian region. The role of distant deep-foci Pamir-Hindu Kush earthquakes as a “trigger” for the formation and mechanism in dispersive water-encroached soils under the influence of prolonged, low-frequency vibrations is examined. There are three groups of landslides liquefaction—extrusion, thixotropic liquefaction and mudslides of gravitational liquefaction. Results of geodetic measurements of large landslides in Angren coal mine for 22–26 years and the role of the Pamir-Hindu Kush earthquakes in their formation are analyzed. Figures obtained of the overriding criterion of velocity 74.4 cm/day and time 79 days in transition of the mass movement into progressive creep of clay material.
