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 areas surrounding the city of Sofia. The main objective of this research is monitoring of the ongoing geodynamic processes by complementary use of SAR and GNNS data. GNSS data from permanent and local geodetic networks are used for validation of the SAR derived information concerning the study area. The study will give reliable data for ongoing risky geo-processes for the region of the Southwest Bulgaria. Landslides are one of the main geological hazards that can cause critical damage to the infrastructure in an area and can result in serious risks to the people?s safety there. Maps of active, stabilized and potential landslides in Southwest Bulgaria provided by the national landslide register part of the GIS maintained by Ministry of Regional Development and Public Works (MRDPW) are used. For mapping the deformations in the studied region interferometric images were produced at 4 months intervals. The results obtained from this study are used for the further development of the methodology for monitoring the risk of geo-processes by combining data from different sources. |
