ABSTRACT
Violation of the stability of the massifs, dangerous geological processes (landslides, land-slips, subsidence, suffusion, karst) are widely developed in the mountain and foothill areas (Urgut) of the Zarafshan oasis, Republic of Uzbekistan. Especially, in recent years, due to abundant of atmospheric precipitation earthquakes and active human intervention in the environment create emergency situations and are accompanied by large material losses, often by human losses.
The main reason of the development and descent of landslides is the over moistening of loan at the contact with bedrock surface and groundwaters, as well as, the formation of landslides caused by seismic effects. At present, more then 20 landslide hazardous and 60 potential landslide plots are under observation. In the zone of acting landslides, there are 57 children’s recreation camps within the mountains and foothills areas.
Ongoing permanent observations for especially dangerous five landslide, located in the Urgut district (the villages: Sayguss, the Guss Upper, the Guss Lower, the Aktash Upper, the Аktash Lower, the Khodjaabdal village) of the Samarkand region of Uzbekistan. The above – mentioned landslides were activated by the landslide that came about and were provoked by a forced explosion on November 13, 1994. The results of long – term observations testify, that heavy rainfall and as wall as high seismic activity have a huge effect on the formation of landslides. Landslides are most intensively developed along high-way. This makes it clear, that developing of mountainous and foothill areas without pre-liminary studies to determine the degree of stability of the slopes and the implementation of protective recommendations becomes one of the main factors in the formation of land-slides.
