Globally, modern crustal movements are being studied as a priority, a large number of projects are being developed and significant funds are being allocated for the development of research in this field of science. Due to the social importance of the problem, the need to obtain geodetic data on the current activity of the earth's crust is realized.
This article examines the study of the temporal movements of the earth's crust and the accumulated stresses in a geologically and seismically active region with the presence of many fault structures. The region around Sofia and southwest Bulgaria is distinguished by many fault structures, and the presence of tectonic and seismic activity, thus implies the emergence of dangerous geodynamic processes. A geodynamic GPS network has been built in the region to study the geodynamic processes. Campaigns with GNSS measurements have been performed for more than 23 years. GNSS data acquired from periodic geodetic measurements between 1997 and 2020 are analyzed to obtain the strain rate field for southwestern Bulgaria. The newly acquired strain rate field show dominating N-S extension and the deformation is not uniformly distributed over the studied area. Some important conclusions have been made about the behaviour of the fault structures. The result for strain rate field confirms that the movement of the points in the region of Southwest Bulgaria is in the southern direction relative to stable Eurasia. This extensive movement of southern Bulgaria and northern Greece is confirmed. Due to the long period of measurements the results are highly reliable and can be used for detailed geodynamic and geological study of the fault structures in the region and evaluation of the seismic hazard. |
