Abstract

The results of research studies from deformation investigation of geotectonic recent movements in east Slovakia are presented. Satellite measurements were implemented in the geodetic network in the Kosice Basin. Transformation of the geodetic points coordinates from WGS-84 into the Slovak national positional coordinate and height system was carried out using Helmert seven-element transformation. The aim of the deformation measurements was determining geotectonic recent movements especially in the urban agglomeration of the city of Kosice. The major tectonic fault in the Kosice Basin, according to which two expressive geological blocks of the top part of the Earth's crust could be each other's move, passes in the line of the north-south direction along the river Hornad which flows through the city of Kosice. 3D modelling deformations in the Kosice Basin are applied into Geographical information systems for utilization of the municipality self-government of the city of Kosice. The deformation investigation outputs confirmed the assumption that for the period 1997-2016 there were recorded no geotectonic recent movements beyond the authorized border safety limits.
