Stress Condition Determination based on Focal Mechanism Data: A Case Study on Kraljevo Earthquake

The aim of this research was to perform stress condition analysis in the area of Kraljevo, based on focal mechanism data of an earthquake from November 3rd 2010, as well as it’s three strongest aftershocks. Focal mechanisms of these earthquakes have been formed based on polarity of first arrivals of P-waves on seismic stations. Also, structural inversion of these data was performed. It was determined that, during investigated earthquakes, strike-slip faults of WSW-ENE were reactivated.
