Recent tectonic activity of the Tatra Mts and Podhale (Poland) studied by InSAR and PSInSAR

Abstract

The paper presents some preliminary results of PSInSAR (persistent scatterers SAR interferometry) processing of the Tatra Mts. and Podhale area in southern Poland. The research is carried out within the framework of a GEO-IN-SAR project aimed to study the recent tectonic activity of selected locations in Poland. As the input for PSInSAR processing 51 ERS-1/2 SAR scenes has been used by obtaining 50 interferograms covering the period from 1992 to 2000. The resulted few hundred PS (Persistent Scatterers) points show relative 1 mm/year uplift of the Zakopane area in respect to Nowy Targ. However, the preliminary interpretation along the transect Zakopane–Nowy Targ shows more complex pattern suggesting recent activity of some faults
