In the Kerch-Tamagne areas, mud volcanoes and associated "pressed synclines" are evolving. The problem of genesis of mud volcanoes is debated; researchers of mud volcanoes do not have a common opinion about the mechanism of their formation. The necessity of studying the mud volcanoes structures is also connected with the...

The 1996 experiment performed at the Physico-Technical Federal Board (Physikalisch-Technische Bundesanstalt, PTB) provided a value of the Newtonian gravitational constant that exceeds the standard value by ~ 0.6 %. In this paper, it is shown that this anomaly does not result from neglecting the Earth's shielding effect.

One of the methods used to monitor the developing geodynamic processes in seismic-prone zones is based on the regular sounding of a medium by powerful seismic vibrators, with a subsequent analysis of the time dynamics of the seismic field parameters.

Such a monitoring is accompanied by certain nonlinear processes taking...

In this paper, to solve the problem of active vibroseismic monitoring of the processes of fracturing and dilatancy in seismic- and volcano-prone zones, we take into account the dynamic characteristics of the wave field, in addition to a tracking change in the coefficients of medium anisotropy and propagation velocities of...

The problem of the tsunami wave generation by the submarine landslide, which is moving along the bottom slope, is studied. A number of numerical experiments were carried out for a model submarine landslide. A maximum amplitude and the wavelength were defined for various landslide profiles and their moving rates. As...

This study deals with technique of interpretation of harbingers of strong earthquakes aimed at operative forecast of seismic danger. Geomonitoring data of a natural impulse of the Earth's electromagnetic field (NIEEMF) together with seismic monitoring data are analyzed. As an instrument for the analysis of a non-homogenous structure, the wavelet...

The present paper deals with the dynamic problem of linearly de-formable elastic media with an arbitrary anisotropy, containing flat parallel cavities-cracks – the so-called viruses of vibration strength of class 2. The new method with allowance for specific features of integrand functions is used for calculation of multi-dimensional inverse Fourier...

In this paper, we describe a 64 bit version of the visualization system for seismic fields. The system supports well-known SEG-Y, SDS-3, SDS-5 file formats or their scientifically adapted versions without headers. This system is used for several years as a part of industrial seismic data processing system in the...

This paper studies the importance of spatial distribution of the sea-level monitoring stations for the accuracy of restoration of a tsunami source. The ill-posed inverse restoration problem is regularized by means of the least squares inversion using a truncated SVD approach. The wave propagation is described by linearized shallow-water equations...
