Conference Paper
Full-text available
The European network of tiltmeters – vertical static pendulums – was established in 2007 (Neumann and Kalenda 2010, Kalenda et al. 2012). Two pendulums were installed in the Prokop Gallery in Příbram at a depth of 2 m and 96 m below the surface. Another pendulum was installed in Cave No.13C in the Moravian Karst at a depth of 60 m below the surface...

The deformation measurement of rock mass in the depth and mathematical modelling solved the old question of Wegener´s theory “What is the main engine for the lithosphere movement?”.The solar energy, which reaches the Earth, is two orders higher than the energy of all earthquakes and volcanoes. Only a small part of the solar energy is accumulated in...
Conference Paper
Full-text available
Resume The vertical static pendulums can measure the changes of horizontal stress in real time. The stress waves result from the nonlinear behaviour of the massif. The „stress waves“ precede the strongest EQs and they are detectable everywhere before M7.5 EQs. The first precursors before M7 EQs are detectable week before the mainshock. The respons...
Conference Paper
Full-text available
We present a new model of lithosphere-plates movement based on three pillars: 1) The thermoelastic wave, which was described first of all by Berger (1975), 2) The ratcheting mechanism, which was described for asphalt buckling and/or lithosphere evolution by J. Croll (2006, 2007), and 3) the solar irradiance energy, as quantified by IPCC (2007). The...
Conference Paper
Full-text available
More than seven years of experience with the measurement of micro deformations of massif by vertical static pendulums, caused by changes of horizontal components of tectonic stress, showed that the lithosphere plates can transfer the tectonic stress to the distance, comparable with the circumference of the Earth. The strong deformations were observ...

Static vertical pendulums have been installed in mines or caves in Central Europe since 2007. The two dimensional optical measurement of tilt of rock mass and continuous full digital on-line evaluation of results makes possible to detect small tilt of the surroundings with resolution of tens of nanoradians or deformation of the surroundings in the...
Article
Full-text available
The depth distribution of seismicity has changed significantly several times since 2000. We can observe atypical low seismicity on the global scale at the Moho depths during the last four months (since June 2013) in comparison with the seismicity of the last ten years. We suppose that some parts of the Moho discontinuity are locked. Such asperity o...

The town of L´Aquila was hit by earthquake on April 6, 2009 (M6.4) and 309 people were killed. Gianpaolo Giuliani predicted such an earthquake on March 23 based on his radon and local seismicity measurement in L´Aquila and its surrounding. He detected two anomalies – one in the beginning of March and the second between March 19 and March 23, 2009....
Data
The earthquake prediction must fulfill at least three parameters: time window, focal area and minimal magnitude of future earthquake. The new measurements of tilt by vertical static pendulums confirm that the best model of the processes inside of focal area before the mainshock could be model of asperity. This model show that quite before the failu...

Data
We analysed three “independent” data sets of three volcanoes (Katla and Hekla on Iceland and Pichincha in Equator) and global seismicity for the time span of the last 500 years. The statistical analysis of volcano eruptions and global seismic activity show that these processes are not independent and random, but they are the consequence of one glob...

The measurement by vertical static pendulums is described in the paper. This apparatus measures the small deformations in horizontal plane or tilt of plumb line. That is why the measurement must be realised in the underground – in caves or abandoned mines. The main aim of such measurement is to detect so called “stress” or “tectonic” waves, which p...

We introduced the asperity model of earthquake prediction, where the nucleation phase of earthquake is proportional with the magnitude of earthquake according the rule log T [day] = 0.46 M – 2.2. In the second part, we analysed our tilt measurement and we showed the "stress waves", which precede the earthquakes.
