Determination of coseismic deformations in the Balkan Peninsula area based on SAR data

Mila Atanasova

Abstract:
The Balkan Peninsula is one of the dangerous seismic zones on Earth, where several seismic events with a magnitude above 7 have occurred in the last 50 years. Most of the seismic events were generated near or in the fault zone. Area known as the Hellenic arc is located near the territory of Bulgaria, and earthquakes that occur there are often felt. In this study, we focused on determining the deformation of the Earth’s surface that occurred in the Balkan Peninsula region after several earthquakes with a magnitude greater than Mw 6.5 occurred in the last 5 years, recorded by NOA and USGS / along the Hellenic Arc. Thanks to InSAR technology, is possible to determine the coseismic deformations of the earth’s crust. The SAR data was used to record the ground motions that occurred by creating interferometric images, from which information was extracted about the subsidence and uplift caused by the earthquake.
