| Abstract: | In connection with the intensive development of the northeastern part of the Black Sea, at present a number of serious technical,
scientific, and ecological problems have arisen. As the constructions being raised are of large sizes and they are designed
for a long period of use, the probability of their damage by natural phenomena significantly increases. First of all, these
are phenomena connected with seismotectonic activity. In the present paper, the current concepts about the regional tectonic
structure are considered. Moreover, a detailed analysis of the seismic activity in the Bolshoi Sochi region and the adjacent
regions is conducted in the historical perspective. The basic results of the marine seismic research carried out by the Institute
of Oceanology of the Russian Academy of Sciences on the shelf and the continental slope of the northeastern part of the Black
Sea during the period of 1998–2001 are presented. On the basis of the scheme of the general seismic zoning developed by the
International Expert Group for the Caucasian Region, a scheme of the seismic hazard in the Bolshoi Sochi region has been constructed.
For the specific zones of the region, the values of the seismic hazard characteristics—the maximum shocks and accelerations
and the periods of oscillations under maximum seismic effect—have been calculated. Some ideas concerning the integrated modernization
of the system for seismological observations in this region, including the deployment of autonomous bottom seismographs and
automatic seismographs in almost inaccessible places, are proposed. |
