缅甸Ms7.2地震前电离层TEC的异常变化

On the basis of the Total Electron Content(TEC) obtained from International GNSS Service(IGS) and the VTEC derived from the GPS observation data from the reference stations of Crustal Movement Observational Network of China and using the method of moving average,we have processed and analyzed the ionospheric TEC prior to the Myanmar Ms7.2 earthquake. The results show that the anomalous reduction of TEC occurred on 6-8 day prior to the earthquake and the anomalous increase of TEC occurred on the 3rd day prio...
