Recent activity of the regional geologic structures in western SloveniaKeywords: recent tectonic activity , geodynamics , levelling line , Kra ki Rob , Southalpine Front , Julian Alps thrust , Ra a fault , Diva a fault , vertical geodynamic activity , Slovenia Abstract: Several important geological structures in the western Slovenia were identifiedas active and their activity was quantified. Geologic interpretation is based on the analysis of repeated leveling line campaigns data along the Se ovlje–Bled polygon. Taking intoaccount the limitations of the method – only the vertical component of displacement is measured – the following structures were identified as active:a juvenile syncline between Strunjan and Koper, the Kras Imbricate Structure, the Diva~a fault, the Ra{a fault, the Southalpine Front and the Julian Alps thrust. Vertical movement rate is relative, calculated with respect to the benchmark in Se ovlje. The largest uplift rate difference between Se ovlje and Bled is 7 mm/a.Vertical Geodynamic Activity (VGA) is introduced as a link between geologic interpretation of geodetic measurements on one side and possible applications on the other as well as a mean of comparison between tectonically active regions.
