Abstract :
Ionospheric variations were observed by DEMETER (Detection of Electro-Magnetic Emission Transmitted from Earthquake Regions) satellite, during strong earthquake. The main aim of the DEMETER satellite mission is to study the ionospheric variations associated with seismic activity. In present paper, we have studied ionospheric irregularities for strong earthquake by using ion and electron density data. These data recorded by the IAP and ISL instruments of DEMETER satellite, respectively. Perturbations in plasma parameter were observed near the epicenter of the earthquake few days before the main shock. Observed variation in ionosphere was examined by checking geomagnetic (Dst and Kp indices) data.
