Ground penetrating radar (GPR) named “Roteg” was used to detect known and unknown passages of Divaška Jama and Trhlovca caves in SW Slovenia. “Roteg’s” main characteristics are an extraordinary high power output (20 MW) and high voltage on

The measurement of deformations of the elevator shaft in the Skutina fortress between the 2nd floor and the depth of 33 m below the surface took place in 2009. These measurements showed that, in addition to the tides, the diurnal thermoelastic wave d

This article shows how the probabilistic SBRA (Simulation-Based Reliability Assessment) Method (i.e. stochastic Monte Carlo approach) is applied to the model of the behaviour of the lithosphere of the Earth (geomechanical model). The main idea is bas

This paper shows the probabilistic SBRA Method application to the model of the behaviour of the lithosphere of the Earth. The method extends our initial work where we created the geomechanical model of the lithosphere. The basic idea was about the ge

Vertical static pendulums have been installed in mines or caves in Central Europe since 2007. Two-dimensional optical measurement of the tilt of a rock mass and continuous fully digital on-line evaluation of results makes possible the detection of a

Annual drift is typical for microseisms. We propose a model based on thermoelastic wave generation that explains the highest microseisms during winter using higher stress level at the same time. If we remove the average influence of the background st

The basic scientific question of this study was: do other mechanisms exist for excitation of secondary microseisms aside from the widely accepted mechanism by non-linear interactions of respective ocean waves. Here we use continuous broadband data fr

A new kind of Ground Penetrating Radar (GPR) ”Roteg“ was tested at generally known speleological sites in the Czech Republic. The first examined site – the Hranice Abyss located in the Hranice Karst – is the deepest underwater cave in the wor

We present results of a study of the seismicity and the geoelectric structure of the Eastern Carpathians. After the evaluation of the seismicity, new methods of processing and analyzing seismic data are developed, which allow constructing an averaged

The seismic network can be used for the localization of the fireball trajectory in the atmosphere. The types of sonic or blasting waves, created during the meteorid’s penetration of the atmosphere, are discussed. The practical use of the localizati
