Nonlinear dynamics, seismic activity and aerospace sounding systems
Journal Title: Геофизический журнал - Year 2015, Vol 37, Issue 2
Abstract
Processes and phenomena are under consideration, which can be realized from the viewpoint of nonlinear dynamics and are typical for geosystems. Attention is focused on the main features and new possibilities given by the ideas and approaches of nonlinear dynamics for solving applied problems of geophysics. Premises for physical interpretation of spontaneous electromagnetic and seismoacoustic emission as a product of temporally uninterrupted transitional dynamic processes related to interaction of different subsystems of geo-medium as its metastable conditions and succession of such conditions are analyzed. An attempt has been undertaken to analyze lithosphere-atmosphere-ionosphere relations, methods of multiparametric aerospace monitoring of short-term precursors of strong seismic events. Its possibilities and limits are considered and the necessity of integrating passive monitoring systems based on the study of medium-generated emission signals spectra with active ones, oriented to system receptivity control. Baselessness of attempts to give reliable and accurate short-term forecast without studying physics of producing destruction sources and development of deformation process within the Earth’s crust during the final stage in a regime with intensification has been noticed.

The structure of the Moldovan iron ore deposit (The Ukrainian shield) according to geological-geophysical data and its possible endogenous nature
An idea of the endogenous nature of ferriferous and ferriferous-carbonate rocks, forming numerous relatively small size of deposits and ore manifestations in the region of the Middle Bug called Pobuzhsky iron-ore distric...
Unsolved problems of the global tectonics and possibility of their solutions
The deep geological and geophysical studies of the continents and oceans have revealed a number of well-defined new regularities in the structure of the crust and upper mantle that do not find a clear explanation in the...
From global tectonics to global geodynamics
Observations suggest that global (plate) tectonics operates on the Earth. The most characteristic features of the global tectonics are ocean floor spreading in mid-ocean ridges and subduction in deep-sea trenches. These...
