ABSTRACT

The Rhodope Mountain (South Bulgaria-Northeast Greece) is the largest mountain system in the eastern part of the Balkan Peninsula. It occupies a median position within the peninsula and thus is close enough to the main tectonic processes in this part of the Eastern Mediterranean (transcontinental collision between the African continental macro plate and Eurasian continental macro plate). This is an important prerequisite for the development of endogenous geodynamic processes with risky nature (earthquakes).The paper presents the results of the study of fractal geometry of the seismic clusters in the Rhodope Mountain. A combined seismic catalog (USGS and IRIS), composed of 640 seismic events (all values) occurring within the mountain massif for the 1965-2016 statistical period, was used in the analysis. Based on the methodology adopted for the calculation of surface fractals, the areas of the individual earthquake clusters were measured and their fractal geometry has been checked. The obtained results confirm the self-organizing nature of the seismic processes operating in the Rhodope region.
