In the given paper there are presented results of analysis of the total electron content (GPS TEC) variations prior to the Japanese earthquake which took place on November 28, 2004. It was revealed the occurrence of the specific seismoionospheric anomaly in the form of local TEC enhancement. The increase of electron concentration reached the value of 40-50% relative to the quiet geomagnetic conditions. For detailed analysis it was considered GPS TEC data obtained for GPS stations located at different distances from the epicenter position, as well as the data of ground-based vertical sounding station.
Keywords: seismoionospheric effects, GPS, GLONASS, total electron content
