Mathematical problems in geophysical investigations of solid Earth

The wave nature of seismic process developing within the margins of the Pacific Ocean is considered. A wave rotation model of seismic process is constructed based on the idea about ro-tation of «elementary» seismofocal blocks under conditions of the Earth’s rotation around own axis. Within the scope of the model, it is shown that there are interrelations among waves of the seismic migration, strain waves and Chandler’s oscillations. On the basis of world seismological data the correlations between velocities of the earthquake migration and magnitude values is found. The earthquake focal source model corresponding to the wave rotary characteristics of seismic process is developed. Following this model an earthquake may be considered as a result of interaction between the tectonic wave and an «elementary» seismofocal block. The basis for the wave geodynamics of lithosphere of the Earth is formulated.
