Application of PSInSAR for observing the vertical component of the recent surface displacements in Julian Alps

Permanent Scatterer interferometry method has been used to observe subtle surface displacements in the north-western part of Slovenia between April 1992 and December 2000. The method proved to be very useful (at least) as indicator of the vertical component of relative tectonic displacements velocity and as the tool to detect co-seismic surface di-splacements. The preliminary displacements in the region (1mm/y about) have been estimated,yet at this stage they are to be taken with restrain.
