Abstract

The invention relates to geophysics, and more specifically to methods for predicting earthquakes based on the registration of precursors using artificial earth satellites. The purpose of the invention is to increase noise immunity and expand the field of control. The goal is achieved by registering the precursors of an earthquake in the region located below the radiation on the Earth itself, as a precursor of an earthquake use the intensity of high-energy charged particles, and the focus of preparation of an earthquake is determined by the maximum of the intensity of charged high-energy particles. in the absence of disturbances of the magnetosphere. The expansion of the field of application is provided by choosing the registration area of the earthquake precursors, as well as the selection of the forerunner-intensity of high-energy particles, allowing registration in areas remote from the equator during the daytime and in the presence of irregularities in the ionospheric plasma.

Description

The invention relates to geophysics, and more specifically to methods for predicting earthquakes based on recording forerunners using artificial earth satellites (AES).

The purpose of the invention is to increase the unsustainability and the expansion of the area of control.

The earthquake prediction method is implemented as follows.

The precursors of the earthquake are registered in the area located under the radiation on the Earth itself, using instruments installed on satellites. The intensity of charged high-energy particles is used as a precursor of the earthquake. The focus of the earthquake preparation is determined by the maximum increase in the intensity of high energy high energy particles in the absence of magnetospheric disturbances. Part of the near-Earth space occupied by the ionospheric plasma belongs to the radiation in the Earth itself.

Electromagnetic clusters arising above the foci of preparing earthquakes spread into the ionospheric plasma region over distances up to several thousand km kilometers. The amplitude of the electromagnetic waves depends on the magnitude of the earthquake magnitude of its depth and decreases with increasing distance from the source of the earthquake. The maximum amplitude is recorded directly above the o "a gomi

Electromagnetic waves caused by seismic activity interact with particles of radiation and cause diffusion of particles at pitch angles. A change in the pitch angles of particles captured by the geomagnetic field, having a higher intensity and characterized by a narrow distribution, leads to the expulsion of such particles under radiation from the Earth. The instruments installed on the satellite register the increase in the intensity of particles under the radiation of the Earth. The magnitude of the particle intensity depends on the earthquake intensity of the satellite as well as on the relative position of the satellite and the earthquake source. Since the intensity of the part, under the radial som, is 10g-10 times less than in the radiative region, the flow of precipitated particles can be registered in any area of the near-earth space under the radiation of som. Since the maximum amplitude of electromagnetic oscillations is recorded in the ionosphere directly above the earthquake source, in these areas there is the greatest effect of electromagnetic waves on the flux of particles trapped by the geomagnetic field and a significant increase in the intensity of particles

The tests of the method were carried out at the Salyut-7 station, Meteor AES, stations. Experiments investigate correlations with earthquakes with a magnitude of more than 4. A change in intensity is observed 10-100 times in experiments at Salyut-7, Mir and 1, 5-3.0 times per satellite

In the experiments at the Salyut-7 and Mir stations, protons with an energy of 30–100 MeV are recorded, and at the Meteor satellite, protons with an energy of more than 400 MeV are recorded.

Magnetic storms and other strong changes in the geomagnetic field, explosions, and technogenic processes do not show correlations with rashes on the results of mop / t. The results are not aircraft with a type of satellite. However, it is possible to choose the parameters of the satellite orbit, at which the method is more sensitive, B about (5 flippers x, where the radiation is located near the surface of the Earth, for example, the Brazilian geomagnetic anomaly, the satellite is longer in the region of highest sensitivity,
