In this study the effect of hazardous geodynamic processes in the area around the city of Sofia is investigated using radar satellite data. The area is of particular interest due to its high population density and high concentration of industrial facilities and residential areas. This highlights the importance of the study area in societal aspect. This the reason the authors set the main objective of this research to be the monitoring of the ongoing geodynamic processes by complementary use of synthetic aperture r...

The focus of this study is detection of the deformations of the Earth's surface caused by March 3 2021 earthquake using Differential Interferometric Radar Synthetic Aperture technique. This method takes advantage of the remotely sensed SAR data provided at no cost by ESAs’ Sentinel-1 mission which are often used for creation of topographic maps as well as for detection of ground motions. The final results of this processing deliver reliable information about the displacements caused by the mentioned events with ce...

Geodynamic processes and seismic activity are considered to be the prime driver of horizontal and vertical movements of the Earth's crust in the Balkan Peninsula. One proven method for continuous monitoring of ground deformations is the use of data from active radar remote sensing. These data are the basis for the creation of interferometric images (IFIs) for quantitatively assessment the recorded ground movements of the Earths? surface within a fixed time interval. For this research a set of IFIs were created for...
