Sažetak
The Dinarides are a part of the complex Alpine– Carpathian–Dinaric orogenic system characterised by NW trend and SW vergence of compressional and imbricated structures. The External Dinarides, their western part, is derived from the Adriatic microplate, i.e. the Adriatic carbonate platform. Recent seismicity in the area varies from moderate to high with the rare occurrence of strong earthquakes. Prevailing compressional stresses result in mainly reverse faulting, with or without a dextral strike-slip component. The southern part of the External Dinarides is the seismically most active area in the External Dinarides, where one of the strongest events occurred: Ston–Slano (1996, ML = 6.0), Montenegro (1979, Mw = 7.1) and Dubrovnik (1667, IX EMS). Therefore, the area shows one of the highest seismic hazard in Croatia. The extended coda normalization method was applied to local earthquakes’ high-frequency body waves in order to estimate attenuation of direct P- and Swaves, i.e. the quality factors QP and QS. The preliminary results of the azimuthal analysis of the attenuation factors clearly indicate anisotropy of seismic attenuation in the high-frequency range, with higher attenuation in the direction perpendicular to the strike of the Dinarides and lower attenuation parallel to it. These quality factors reflect the total attenuation of the direct body waves in the crust and therefore reflect its features. Furthermore, these results indicate strong attenuation of the direct P- and S-waves in general.
