Several important geological structures in the western Slovenia were identified as
active and their activity was quantified. Geologic interpretation is based on the analysis
of repeated leveling line campaigns data along the Sečovlje–Bled polygon. Taking into
account 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 Divača fault, the Raša fault, the
Southalpine Front and the Julian Alps thrust. Vertical movement rate is relative, calculated
with respect to the benchmark in Sečovlje. The largest uplift rate difference between
Sečovlje 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.
