Abstract: In this paper, we review recent advances and latest developments on the study of ionospheric disturbances prior to earthquakes. We also introduce DEMETER satellite and some statistical studies and earthquake case studies based on DEMETER satellite data. The common steps for studying ionospheric phenomena before strong earthquakes are expounded: select the earthquake examples-choose the parameters of the ionosphere-data analysis, extract and identify disturbance information-validate pre-earthquake ionospheric responses. The electromagnetic effects and correlated phenomena generated in seismo-electromagnetic process, spread to space by ways of chemistry, acoustics, and electromagnetism. The research results show clearly that ionospheric disturbances appearing several months, days or hours prior to earthquakes can be observed. whether the precursors could be used as a tool in earthquake prediction need more research.

Key words: Seismo-ionospheric disturbances, DEMETER Satellite, Statistical research, Earthquake case study
