Let us consider the propagation of magnetoacoustic waves in the porous media saturated with electrolyte in the case when the loss of energy occurs due to electroconductivity, intercomponental friction coefficient and electrokinetic effect.
The fundamental solution to describe the three-dimensional steady-state flows of viscous fluids of the two-velocity continuum with pressure phase equilibrium has been obtained.
This paper presents the results of experimental investigations of the original ecologically safe approach as related to the assessment of the geoecological risk from powerful mass explosions for the social and natural environment. In this approach, seismic vibrators are used as sources imitating…
The method for estimating a tsunami height using the wave front kinematics computation has been developed and tested. This method is based on an orthogonal advance of computational points located along a moving tsunami wave front line. Precise algorithms for determining these points movement…
The new meaning or a property of the Gaussian and of the mean curvature of surfaces forming a family in terms of the vector analysis has been discovered. The divergence representations were found for the mean curvature H = H(x; y; z) and the Gaussian curvature of K = K(x; y; z) of the surfaces Sα…
The divergence formulas we have obtained (differential conservation laws) of the form div F = 0 for an arbitrary smooth field of unit vectors τ(x; y; z), for a family of spatial curves as well as {Lτ} for a family of surfaces {Sτ} continuously filling a certain domain. The solenoidal vector field…
The use of the shady relief model of the ENDDB-program (the Earth's Natural Disasters Database) and the data from “Global marine gravity”, V18.1 for constructing the relief and the shaded gravity anomaly maps allows us to visually reveal the new morpho-structural elements of astroblemes or to…
This paper outlines some aspects of an approach to reconstructing an initial water elevation field that generates a tsunami. Recently, the devastating tsunamis have acutely put forward the problem for their timely warning and, as consequence, the importance of the accurate tsunami simulation…
