Tracking the local seismicity level in the active influence zone of the southern Uzbekistan reservoirs

Assessment of local seismicity caused by human engineering activity is a necessity after several earthquakes have been recorded in world practice, which destroyed hydraulic structure, dam and accompanied casualties. The Tupalang, Gissarak Pachkamar reservoirs, operated southern Uzbekistan, are located the mountain system part Tien Shan seismogenic fault. According to general seismic zoning, zones where these reservoirs classified as 8-9 magnitude shakes during strong earthquakes. Localisation associated with operation necessary for taking operational measures prevent possible emergencies an increase level technogenic seismicity. Methods assessing regime were used track catalogs occurring zone active influence compiled. levels changes angle inclination recurrence determined each object separately. dependence variation on mode has revealed. Several evidence negative impact large deformation state Uzbekistan identified.
