General directions
Areas of research:
· Study of the seismic regime and seismic hazard assessment;
· Overall, detailed and microseismiczoning of territories;
· Monitoring and prediction of earthquakes;
· Evaluation of seismic risk and prediction of damage from earthquakes;
· Geodynamic monitoring and forecast of dangerous technogenic processes;
· Creation of databases in the field of seismology.
Monitoring of seismic regime carries out the Experimental-Methodical Seismological Expedition by Kazakhstan.
The experimental base consists of a network of integrated geophysical observatories, seismic, hydro-geochemical, hydrodynamic stations, geophysical observation points, biological objects, points of space geodesy GPS, chemical laboratory, data acquisition and transmission, a local center, data bank.
At the territory of Almaty, the engineering seismometric service of 15 points is established, it has a digital strong motion stations ETNA, directed to solve the problems of seismic zoning. For continuous earthquakes of varying strength and distance, a complex of modern equipment, including a digital seismic station IDS-24, GSR-18, Q-730, DAS-6102 and seismic system "Volcano" is used. For monitoring of current crustal movements, the works on Space Geodesy and GPS are carried out. Processing incoming information is carried out with the use of modern information technology and software.
The main results of fundamental research:
- The foci of earthquakes with a magnitude of more than 6.0 are formed mainly in the granite-gneiss of the earth's crust, and with M ≥ 7,0 are located at the interface granite-gneiss and basalt layers. Correlation between the parameters of the seismic regime and changes of modern movements of the earth surface.
- The two-dimensional P and S-velocity and density models of the Earth's crust on new geotraverses are developed. The technique of seismic parameterization of seismogenic zones is developed, and the parameterization of Jungar-North Tien Shan region is carried out. The mutual coordination of P-velocity and density models for geotraverses Turkestan, Tamdybulak-Farabi, Farabi, Babatag, Tejan-Karabekaul-Koitash is held. For the same geotraverses, the S-speed simulation, with taken into account the correlations of Vp, Vs and ρ, is carried out.
According to the results of basic and applied research, the next maps are developed:
- seismic zoning of West Kazakhstan region on a scale of 1:1,000,000;
- seismic zoning of the Almaty region on a scale of 1:1,000,000;
- seismic zoning Zhambyl scale 1:1,000,000.
