| Abstract: | The anomalous changes of the ionospheric electronic density in the space over the regions of Kuril Islands earthquake on Nov. 15,2006 and Haixi(China) earthquake on Feb. 25,2007 had been observed by use of the GPS radio occultation for COSMIC satellite before those events and those anomalies were proved through refering to the indices K from Wuhan geomagnetic station as it was not related to the influences from actions in outer space.Therefore,it can be concluded that the GPS radio occultation technique can be used for monitoring the anomalous change of ionospheric electromic density in the space over the region where an earthquake may occur imminently because these anomalies are probably caused by the generation of earthquakes. |
