Tidal Station Vyhne
Our department operates tidal station Vyhne in the south-central Slovakia situated in Neogene volcanics setting of the Štiavnické vrchy Mts., in the mining gallery of St. Anton of Padua. The main instrument of the station is an extensometer based on a 20 metre quartz tube.
Development and implementation of analytical (method of crosswise superposition, of homogeneous solutions) and discrete methods of solving linear elasticity rock mechanics problems with gravity loading. Presently, the main objective is their application to the investigation of the behaviour of speleothems (cave sinter formations) under gravitational and inertial loading, with the aim to make conclusions about paleoseismicity and paleotectonics.
The main subject of the work is a numerical modelling of the deformation characteristics of the rock structures by means of finite element method (FEM) applied in the field of gravimetry and geodynamics. The particular application is the modelling of the influence of the cavity effect on the tidal tilt measurements.

Our department operates a tidal station in Vyhne. The tidal station is located underground, in the gallery of St. Anthony of Padua in the Vyhne valley, Štiavnické vrchy Mts., Central Slovakia. Currently, it is equipped with quartz tube extensometer measuring the long-periodic (Earth's tides, annual temperature variations etc.) and aperiodic (tectonic) deformations of the Earth's crust. Since the end of 2005 the station is equipped with an α–particle counter to monitor the Radon emanation. In the beginning of 2006, a radio-frequency telemetric link connecting the seismological and tidal stations was established. With the satellite data connection of the seismic station Vyhne with the headquarters of the Geophysical Institute provided earlier, the data route from the tidal station's datalogger to our Bratislava workplace is now complete. Thus, the data acquisition process can be controlled better and the dropouts of data are prevented or minimized.
