Abstract
Management of earthquakes as an important natural disaster for high seismic regions is regarded as a critical task. Therefore location of high risk seismic regions and prediction of the earthquake is very important. By timely prediction of earthquake, it would be possible to control and reduce the hazards and loss of lives and Properties.

Many seismic, geodetic, electromagnetic, biologic and many other earthquake precursors have been reported but scientific communities have often been in doubt about the usefulness of short term earthquake precursors because of the lack of a reliable mechanism for the sources of these precursors. Recently Freund has introduced a new theory for the mechanism of these precursors named P holes theory which can be applied to many of the bove mentioned precursors. However, now investigations in this field are followed with a greater concern. At the other hand advancements in remote sensing technology have lead to considerable progress in detection of these signals.

In this paper, different electromagnetic earthquake precursors such as the low frequency electromagnetic signals, change of earth magnetic field, ionospheric perturbations and ionosphere total electron content changes have been evaluated. Potentials of the remote sensing satellites like Cosmos 1809, quakesat, Demeter for detection of these precursors have been investigated. Finally contribution of future satellites and remote sensing projects for prediction of the earthquakes has been reviewed.
