Long-term monitoring of recent crustal movements in the region of Southwestern Bulgaria. Results from 2022

Abstract

This article examines the study of modern crustal movements in the region of southwestern Bulgaria, a geologically and seismically active region with the presence of numerous fault structures. The main method of obtaining deformation information is by using GNSS measurements. The monitoring of geodynamic processes in the area has been going on for more than 25 years. GNSS data obtained from periodic campaign measurements between 1997 and 2022 are processed and analyzed to obtain the deformation accumulation result in southwestern Bulgaria. As a result of long-term measurements, more and more accurate and reliable results are obtained for the velocities of the points. A certain relationship has been established between the modern movements of the Earth’s crust, seismic events and tectonic structures. This extensive movement of southern Bulgaria and northern Greece is also confirmed. The results can be used for a detailed geodynamic and geological study of the active fault structures in the area.
