[MIS27-P03] Investigation of preseismic- ionospheric disturbance observed by the DEMETERs

3-min talk in an oral session

Keywords:Earthquake, Ionosphere, DEMETER

We investigate pre-seismic- ionospheric disturbance observed by the DEMETER. The data was ISL (Electron density and temperature) and IAP (Ion density and temperature). Since there are several papers concerning the pre-seismic ionospheric disturbance by using the data of electron/ion densities and temperature, we verify the reported pre-seismic anomalies by means of superposed epoch analysis.
