Abstract:

Starting in 1994, the monitoring network of the RSE Institute of Geophysical Research consisted mainly of sensitive seismic arrays of different configurations operating in the territory of Kazakhstan. Seismicity monitoring of Kazakhstan has revealed a significant number of earthquakes in regions that were traditionally considered as aseismic. A range of earthquakes is related to places of induced seismic activity. The report gives information on events of an induced and man-made nature in the territory of Kazakhstan using contemporary instrumental data from a regional monitoring network, and data of the International Data Centers. The man-made earthquakes occurred at solid mineral deposits (Zhezkazgan deposit in Central Kazakhstan, gold ore quarried of Northern Kazakhstan); at raw hydrocarbon deposits (oil and gas Tengiz deposit, gas condensate Zhanazhol deposit); at former Semipalatinsk Test Site. Natural-induced (induced) earthquakes (in Central and Western Kazakhstan) were also studied. Possible reasons of its occurrence are considered. The wave pattern of records from sources of different nature from the same region are analyzed for reliable discrimination.
