An attempt to detect earthquake-related Ionospheric disturbances with the use of GPS data

[ABSTRACT] Ionospheric disturbances preceding large earthquakes have been reported, recently. Those are devided into two types; one is transmission anomaly of radio station signals such as VLF navigation system (Omega system) and VHF broadcasting signals and the other is anomalous density distribution of ionosphere. As for latter one, convincing results were reported by Liu et al(2000, 2001). It was pre-seismic ionospheric phenomena associated with Chi-Chi earthquake, Taiwan (21/09/1999, Mw 7.8) by using Ionosonde. The aim of this study is to verify the ionospheric disturbances of electron density associated with large earthquakes. In this paper, we analyzed total electron content (TEC) variation with the use of GPS (Global positioning System) data around the day of Tottori earthquake (06/10/2000 M7.3) and Geiyo earthquake(24/03/2001 M6.4).
