Serant O. Deformations of the crust of Europe according to the GPS - measurements and their correlation with seismic activity

Object - the stress-deformation state of the European continent.The algorithm of the calculation of the velocity of horizontal deformation of the earth's crust is developed. The velocity of the deformation on the territory of the central Europe is determined. The earth's crust dilation value is determined and also its spatial distribution that depends on changes of the density of the stations. The author has conducted the analysis of the changes in geodynamic situation on the territory of Europe during the last 15 years (from 1995 to 2010). The concept of scattering of an ellipse epicenter of an earthquake on the limited territory is introduced. The correlation (0.42 - 0.86) between small half-axle of the ellipse scattering of the magnitudes of the epicenter of earthquakes (formed by weak earthquakes) is established; and also between maximum and minimum axes of distension (contraction) of an area. The correlation between the velocities of the earth's crust deformation and the seismicity on the Vranch area is defined. It is established that the time distribution of deep earthquakes on the Vranch area is characterized by periods of seismic activity and quietness. It is determined that the total magnitude correlates with the difference of the next period of quiet deformations and seismic activity (k = 0, 6). Changing of the rate of deformation in the epicenter of earthquakes is with opposite signs between periods of quietness and seismic activity. The author deduces mathematical dependency for determining post seismic deformations of the solid surface of the earth within the seismic period on the Vranch area.
