Seismogenerating structures, which are the tectonic basis of the upper-crust zones of earthquake sources, are mainly represented by suture zones of deep-seated faults. The classification of suture zones reflects their common type in various inner continental orogenic and platform areas, as well as in marginal conti­nental island arc systems. It is shown that the seismic potential of suture zones is mainly controlled by the degree of recent tectonic mobility in these regions. For platform areas, the dominant vector orientation of recent vertical movements Ts also important. In addition, the glacio-isostatic factor may be decisive for the areas covered by late Neo-Pleistocene glaciers. The complicated structure of the majority of suture zones determines a variety of mechanisms of earthquakes associated with them. The recommendations are suggested for improving the seismic zoning using suture zones as seismogenerating structures.


Key words: fault, suture zone, seismogenerating structure, zone of earthquake sources, orogen, platform, glacioisostasy.

The grain-size distribution and toxic elements were investigated in the oil field D-6 in the South-East Baltic. The results of monitoring Kravtsovsky oil deposits field sediments (0-5 cm) and contents of toxic elements (Cu, Cr, Cd, Pb, Hg, Ba) in them were investigated. The chemical elements are distributed in according to granulometric fraction rules. Our data were compared with the mean Swedish data and stan­dards. The sediments of monitoring area are not contaminated by the studied toxic elements. But there was discovered the tendency of elevation of elements concentration in sediments during building of oil platform and exploitation.


Key words: oilfield, toxic elements, bottom sediments, Baltic Sea.

The scope of the paper is the current radioecological and geochemical situation in the north-west of the Kola Peninsula. The study of ecological and geochemical environment in this area is an important task because of a high concentration of potential and existing sources of pollution here. The environmental situation is mainly controlled by the operation of radiation-dangerous enterprises, one of them being the "Nerpa" ship reparation yard specialized in the disposal of decommissioned nuclear submarines of the Russian Navy since 1992. The purpose of the study is to analyze the anthropogenic impacts of nuclear industry on the landscapes in the northern territories by the example of the northwest Kola Peninsula. The area is located in the territory of the south-tundra acidic landscapes.


Key words: ship reparation yard, podzols, podburs, peat soils, I37Cs, heavy metals, lateral and radial migration.

A procedure of geochemical mapping of the water area bottom is proposed. It is based on the subdivision of the primary data into two components, i.e., systematic (regional) and random (local). The former is used for the identification of rather large radiogeochemical regions; and the latter, for the identification of local anomalies and evaluation of their properties. The systematic component of the radiogeochemical field is determined from trend-analysis. Next, radiogeochemical zoning of the water area is accomplished using cluster analysis followed by compiling contour maps of local component of radiogeochemical fields represented by value deviations in the point from the trend. Practical application of the procedure is shown for radiogeochemical mapping the water areas in the east Gulf of Finland.


Key words: procedure of geochemical mapping, sea and lake bottom, radiogeochemical zoning, local anomalies radionuclide, trend-analysis, cluster analysis, practical application of the procedure.

Macroseismic data of past events are used to simulate expected shaking intensity in emergency mode with "Extremum" System application. Influence of regional peculiarities of seismic intensity attenuation and uncertainties in event parameters determined by different seismological surveys on reliability of earthquake loss estimation in emergency mode is studied. The events in Italy (2009), Kurchaloi earth­quake in Russia (2008) and other events in the Northern Caucasus are used as examples showing that the proper regional parameters of intensity attenuation laws (which are typical for the area under study), corresponding ratio of ellipse semi-axis, and their orientation increase the reliability of loss estimations in emergency mode.


Key words: earthquake loss estimation, regional peculiarities of seismic intensity attenuation.
