Modeling the 2D seismic waves propagation from singular sources in porous media based on the Laguerre spectral method

A linear two-dimensional problem in the form of dynamic equations of porous media for the components of velocities, stresses and pressure is considered. Dynamic equations are based on conservation laws and are consistent with the thermodynamics conditions. The medium is considered to be ideal (there is no energy loss in...

On the search for new impact structures based on the "orbital" hypothesis

In this paper, a cosmogenic "orbital" model of formating astroblemes on the Earth's surface is used for the search for new large structures of the impact origin. Because of the only known exact parameter of this model is the distance of 23.25° between the round-the-world turns of a cosmic body...

Modeling the infrasonic and seismic waves propagation from various types of singular sources in the Atmosphere-Earth interface

In this paper, we consider the results of the numerical simulation of the propagation of seismic and acousto-gravitational waves for the spatially inhomogeneous "Atmosphere-Earth" model. The seismic wave propagation in an elastic half-space is described by a system of first order dynamic equations of the elastic theory through interconnection of...

The dynamics of parameters of individual earthquake swarm sequences in different geotectonic settings

To study the swarm sequences of earthquakes in the areas of plate convergence and divergence, the parameters: surface wave magnitude MS and depth H are used, as well as one of the characteristics of the seismic regime — creepex CrNcat, included in the complex of the...
