EXPERIMENTAL RESEARCH AND VISUALIZATION OF CONTEMPORARY GEODYNAMIC MOVEMENTS

Abstract

Methods and results of experimental research of modern
geodynamic movements using strain monitoring data,
and related issues of modeling natural, man-made and
ecological systems are presented. The parameters of the
current geodynamic movements have been calculated by
determining the difference between the spatial coordinates of observation points obtained by satellite geodesy
methods from international geodetic networks.
The paper outlines main provisions of the technique for
visualizing geodynamic movements based on the results
of cyclic geodetic measurements, which makes it possible
to reasonably identify active geological structures,
blocks and tectonic faults. Based on experimental data, it
establishes the vortex character of modern geodynamic
movements as an indicator of active tectonic disturbances. An important characteristic of the vector field of
geodynamic movements is divergence, which characterizes the degree of convergence or divergence of the vector flow.
We show that as a key source of information about geodynamic movements carried out on large space-time
bases, it is advisable to use not the absolute values of the
displacement vectors of observation points, but their
velocities reduced to the annual cycle. This allows, in
terms of existing mining enterprises, to solve the problem
of loss of reference points of the observation station, by
the partial rotation of the landmarks due to the restoration of destroyed and adding new ones in the geodetic
construction.
The tasks for further research are set, including: solving
the question of possibility to increase the efficiency of
obtaining the results of geodynamic studies by using
accurate ephemerides of different classes in calculations,
as well as solving the question of choosing the minimum
possible interval between the cyclic series of instrumental measurements, in which the errors of individual
measurements will have a minimal impact on the result
of determining the speeds of current geodynamic movements.
