The Republican Center of Seismological Service of the National Academy of Sciences of AzerbeijanTalat Tagiev and Arif Gasanov
Research-and-production activity of CSS NASA is directed on the following:
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).
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
