The Dynamics of High-energy Cosmic Rays In Near Earth Space and Earthquake Prediction
Abstract
The existence of correlation between short-term variations of high energy charged par- ticle fluxes in the near Earth space and seismic activity was discovered at the end of 1980s in MARIA experiment on board SALYUT-7 orbital station. Basing on 15 years investigations of high energy charged particles fluxes dynamics in magnetosphere by means of instruments installed on spacecraft it was found the correlation between the variations of particle intensities and earthquakes as temporal and spatial as well. It dis- plays as the sudden increases of counting rate of charged particles several hours before active phase of earthquakes with magnitudes more then 4 (Richter scale) The detailed study of electron and proton flux variations under the radiation belt was continued by means of MARIA-2 magnetic spectrometer on board MIR orbital station, and by in- strument ELECTRON on board INTERCOSMOS-BULGARIA-1300 and METEOR- 3 satellites. The results of analysis of bursts of high-energy charged particle fluxes on the base of these experiments and data of GAMMA and SAMPEX satellites as well are presented. All these experiments confirmed the existence of correlation between short-term sharp increases of particle intensities and seismic phenomena. The possi- ble nature of this correlation is discussed. The phenomenon is explained by resonance interaction of VLF electromagnetic emission of seismic origin with charged particles trapped in radiation belt above an epicentre and following drift of disturbance along the longitude in the same L-shell as epicentre has. The fact of spatial correlation of epicentre position and place of registration of intensity variation gives the possibility to obtain the coordinates of future earthquake some hours before its beginning with accuracy up to 100 km in real time and so use this precursor in practice.
