Short summary
Based on κ values, estimated from local earthquakes recorded by seismological stations situated in the western part of Croatia, regional near-surface attenuation is defined. It shows that attenuation properties of rocks in the northwestern External Dinarides are far from isotropic. The most likely anisotropy sources are the preferential orientations of cracks and fractures under the local tectonic stress field, trapping of waves along major faults, and/or attenuation within the fault zones.
