| Abstract: | By use of the data from three IGS stations located in the area of Mw9.0 Japanese earthquake,the total ionospheric electronic content(TEC) values in four days before and after the earthquake were obtained.There was an explicit ionospheric disturbance phenomenon on that day by analyzing and comparing the computational results.The TEC disturbance phenomenon can be found from different satellite data,which become insignificant with increased distance between the stations and epicenter.A four-day average TEC values before and after the earthquake are computed.The results indicate a significant increase of mean TEC for a few hours after the earthquake. |
