Topical issues of seismic monitoring in the Kaliningrad region
This article analyses the data on seismicity of the Kaliningrad region and addresses the issues of introducing monitoring seismic observations in order to identify previously unknown seismic areas at the regional scale alongside a more accurate identification of the seismic hazard of ...
Urban Planning Development and Seismic Safety Provision in the Kaliningrad region
In this study, we analyse today’s urban development trends in the context of densely populated territories located in moderate seismic regions. We perform a brief engineering analysis of the consequences of the Kaliningrad earthquake of September 21, 2004. The earthquake was felt across the Sambia Peninsula, in the Baltics, Finland, some parts of Poland and Belarus, and even ...
About the method of estimating the parameters of seismic signals

The goecological seismic risk associated with the construction of an underground gas storage in the Kaliningrad region
This article justifies the methodology for assessing the geoecological seismic risk associated with the construction of the Kaliningrad Underground Gas Storage (KUGS). A modified Leopold matrix helped obtain semi-quantitative seismic safety estimate for the object under consideration. The risk assessment is taken into account ...
Joint modeling of elastic and acoustic waves in the Arctic
Numerical solutions of seismic prospecting problems in the Arctic is presented. Results of numerical modeling of the explosive impact on the iceberg and earthquake impact on the oil storage are considered as well. The complete system of equations describing the state elastic ...
Numerical modeling of wave processes in 3D fractured media
Seismic response from the cluster of vertical oriented cracks is simulated using grid-characteristic method on parallelepiped structured meshes. Synthetic seismograms and wave fields are calculated. The structure of the response including dependency on ...
Use of results of interpretation of scattered waves on the CSP method at the assessment of resources of the field of hydrocarbons with fracture collectors
Results of an assessment of resources of a field with fracture and cavernous type of a collector are given. The technique of complex interpretation of seismic data on the CSP method is described, allowing to receive such important parameters, as the area of distribution of a fracture collector and its thickness. Importance of exact definition of a form and the size of deposits in carbonates and granites ...
Algorithms of determining of bodies in a 3D irregular point cloud
A technique for recognition of shapes of bodies in a 3D point cloud is de-scribed. At the first step cloud clustering is conducted using the criterion of maximum distance between the points to identify the bodies being determined. Then proceeding to voxel presentation is being done. Existence of a tetrahe-dron with its points in cloud points and size-limited sides for which the voxel being tested is internal is treated as a criterion of belongment of voxel to a body. A fast algorithm for voxel tetrahedron...
Algorithms and software for building three-dimensional models of microseismic monitoring data
Algorithms for constructing three-dimensional models of microseismic activity fields are described. The first approach is based on voxel models and involves the construction of polygonal surfaces of interpolated parameters of microseismic events. The second approach uses a triangulation algorithm based on the Delaunay criterion and α-shapes method. Software developed on the basis of the proposed algorithms, offers advanced graphical tools for the analysis and interpretation of microseismic multiparameter...
