Geodynamic interpretation of the Central Mediterranean combining geological and 
VLBI data.
 
                   ABSTRACT
 
 
The Central Mediterranean  is a very interesting place to test
the use of VLBI data for geodynamics interpretation.  It is a very
tectonically active area which means that the movements of the different
blocks are quite fast. There are three stations distributed over this area
and located on the different blocks involved. And finally the geodynamic
setting is now quite well known even if there are still some controverses.
In this paper we compare the results of our plate tectonics model with the
velocities obtained by VLBI method and we will discuss the geodynamic
meaning of the relative motion vectors.
The plate tectonic model show that the rollback of the apenninic subduction
hinge slowed down during the evolution the orogen with drastic change when
the Southern Apennines  front collided with the Puglia swell. The Adriatic
plate has to be divided in two sub-plates separated by the Tremiti line.
The results obtained by VLBI method are in good agreement with the
velocities derived from the geodynamics model.
