The Republican Center of Seismological Service of the National Academy of Sciences of Azerbeijan

Talat Tagiev and Arif Gasanov


The republican Center of Seismological Service of the National Academy of Sciences of Azerbaijan (CSS NASA) is the main seismological body of the republic. CSS NASA was founded under the order of directive bodies of Azerbaijan in 1979.
Research-and-production activity of CSS NASA is directed on the following:
  • the study of seismicity on the territory of Azerbaijan
  • the study of features of statistical and dynamic parameters of seismic field
  • the study of mechanism of seismic center, on specification of seismic tectonics elements and oil and gas prospects of seismic zones based on seismological data

Alongside with seismological research, CSS NASA carries out a big complex of geophysical and geochemical work on revealing the seismically abnormal effects arising before earthquake in the variations of intensity of geomagnetic field, electromagnetic radiations, in the variations of gravitational field and the second derivatives of gravitational potential, in the parameters of hydro geochemical, gas geochemical and radio geochemical fields.
Figure 1 shows the network of CSS NASA. Untill 2000 the network of seismic stations consisted of 19 permanent and 3 temporary stations equipped with short-periodand broadband seismometers, allowing to register earthquakes in a range of frequencies of 0,05-20 Hertz, and also with seismometers for registration of strong movements (threshold of abrasion 3-4 points).

In the beginning of 2000 six seismic stations (Baku, Pirkuli, Mingechevir, Sheki, Gandzha, Shamkir) were equipped with digital seismographs with telemetric connection channels (manufactured by Italian company ISMES Spa).
In the beginning of 2001 with the purpose of further modernization of the seismological network, on the basis of tender 15 complete sets of telemetric system of seismic monitoring by "Kinemetrics" company (USA) were purchased. Creation of a new network on the base of "Kinemetrics" system has been completed in March, 2003.
Stations of this system are placed on eight working (Baku, Nardaran, Guba, Pirkuli, Ismailli, Sheki, Gandzha, Lenkoran) and seven newly opened seismic stations (Devechi, Gobu, Gala, Ali-Bayramli, Dzhalilabad, Barda, Nakhchivan), see Figure 2.

One of the main advantages of the new system of seismic monitoring is the opportunity of collection and processing of the data in real time. Transfer of the information is made via satellite connection channels.
In the near future will be opened the web-site of our organization and we shall at once let you know the address of the site.
