| Abstract: | It has been proved by a number of researches that the ionospheric anomalous disturbance do appear a few days or hours before earthquake. On the basis of Total Electron Content (TEC) obtained from Internet GPS Service(IGS), by use of the method of moving average, the 50 Ms≥7.0 earthquakes all over the world since January 1, 2007 were examined.The statistical results show that, excluding the other possible factors, there were significant ionospheric disturbances including ionospheric anomalous increase and anomalous decrease before the 94% of all the earthquake onset, and the apparent anomalous decrease occurred within 7 days before the earthquake but the anomalous increase is not the function of the time. |
