摘要：Earthquake is one of the most horror natural hazards that cause a lot of damage. So, humans always have been looking for approaches to predict it so that they can reduce its damage. For this purpose, a wide range of researches have been done in a number of fields. Although some researches have been claimed to reach hopeful results in prediction of a few earthquakes, no general and proved methods have offered for it, yet. On the other hand, applications of remote sensing techniques are being developed because of its advantages (e.g. wide cover, short period of updating, high resolution data and on-time processing methods). In this direction, recently many researches have been trying to use abilities of this technique for earthquake prediction. Earthquake clouds, measurement of temperature anomalies, ground surface displacements and ionospheric perturbations can be enumerated. Among the above-mentioned earthquake precursors, ionospheric perturbations are so promising. DEMETER (Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions) satellite was launched on 29 June 2004, in a polar and circular orbit with an altitude 710 km, with the aim of collecting a number of ionospheric parameters to study the relations between their perturbations with seismic
