Increase in the accuracy of determination of the parameters of seismic sources using the vibroseismic method for Earth’s sounding

It is proposed to increase the accuracy in the determination of the seismic sources’ coordinates and power, taking into account quantitatively the kinematic and dynamic anomalies of the seismic field, associated with a considerable spatial non-homogeneity of the Earth along the traces of the waves’ passage and in the places...

Expansion of a harmonic source seicmic field

A vibroseismic method of studying the Earth’s deep structure has been most intensively used in the last fifteen years. Much progress has been made toward the creation of powerful seismic vibrators with precise amplitude- frequency-phase characteristics as well as toward methods and instruments for measuring the wave field parameters in...

Method for geophysical exploration based on the interaction of waves with the Earth’s magnetic field

The induction seismomagnetic effects arising in the seismic wave motion in the Ktant Earth’s magnetic field are numerically studied in this artical. The phenomenon is described as a simultaneous solution of the system of elastic equations quasistationary Maxwell’s equations with displacement velocity components, solving the problem we use numerical-analitical algorithm...
