Abstract


SATELLITE INTERFEROMETRY FOR GROUND DEFORMATION MONITORING, LGOM EXAMPLE

Abstract. The article presents surface deformations and changes in the Rudna mining areas, which occured between 28 November and 10 December 2016. These changes were recorded on the radar differential interferogram derived from the scenes of the ESA radar satellite Sentinel-1. The interferogram is a raster image that is a combination of two radar scenes, showing the phase difference of the reflected microwave signal. This difference reflects changes occurring on the earth surface in the form of interferometric stripes called “fringes”.
They are interpreted as contours of changes in earth morphology. During the analyzed period, 3-cm variations were identified. All indications show that they were related to the November 29 seismic shock, which was confirmed by comparing the location of the earthquake epicentre with the recorded fringes.
