| 标题： The problem of interrelation of severe space weather and earthquakes: Current state and future Russian-Chinese cooperation for earthquake hazard mitigation | |
| 摘要： The state-of-the-art research of possible interrelation of space weather with the earthquake source is discussed. The results obtained recently demonstrated again, in spite of certain skepticism, that this interrelation may be used for seismic hazard mitigation. Both impacts of the earthquake source on ionosphere, as well as impacts of space weather on deformation processes in the Earth crust resulted in earthquake triggering are considered. Based on the results obtained to-date the Russian-Chinese cooperation project "Space weather and earthquakes" was launched this year. The project is directed to further study of interconnection of processes in the "ionosphere-atmosphere-lithosphere" system in the seismic-prone regions for solving the problem of seismic hazard mitigation relevant for Russia and China. The specific objectives of the project are to refine existing models of the relationship between the earthquake source and space weather parameters based on data of space monitoring by Chinese satellite CSES-1, as well as to analyze the degree of an influence of variations of the space weather parameters on deformation processes in the earthquake source and the possibility of triggering the seismic events by strong ionospheric disturbances. The scientific novelty of the project is to obtain new results on possible ionospheric precursors of strong earthquakes according to new data from the CSES-1 satellite and their theoretical justification, as well as the physical justification (or rejection) of the possibility of earthquake triggering by strong bursts of geomagnetically induced currents in conducting seismogenic faults of the Earth crust during severe space weather. The project provides for an analysis of satellite observations over the seismic-prone regions of Russia and China, the refinement of the model of ionospheric-lithospheric relations, a numerical analysis of induction of telluric currents in the conducting zones of the Earth crust (faults) by strong geomagnetic disturbances and their effect on deformation processes in the earthquake sources. Physical modeling will be performed at laboratory set-ups for studies of the process of generating telluric currents and their concentration in the conducting model fault, the laboratory "earthquake" triggering by electric pulses at spring-block models of seismogenic fault, as well as the process of rock failure under electromagnetic impact. The results of the project will have a fundamental importance in terms of understanding the relationship between space weather and Earth seismicity and can be used in future technologies of the short-term earthquake prediction. The first results of the statistical analysis of the impact of space weather on the parameters of repeating earthquakes observed in China, Russia, Japan, and the USA are presented. It is shown that electromagnetic perturbations in ionosphere resulted in the flash of geomagnetically induced currents in lithosphere lead to shortening the recurrence interval of the repeating earthquakes similar to dynamic impact of remote strong earthquakes that strongly supports the idea of specific earthquake triggering from space. The reported study was funded by RFBR, project number 21-55-53053 and NSFC, project number 4201101274. | |
