Background

  A number of reports have been produced on the electromagnetic phenomena associated with earthquakes, such 
as ULF/ELF/VLF emissions, air glow increase, changes of electron density and temperature in the ionosphere and 
charged particle precipitation. The number of reports on TEC changes with seismicity have also increased rapidly in 
the recent years.

  It is still uncertain, however, that how the earthquakes influence the ionosphere and by what mechanism. 
Therefore, it is also true that researchers skeptic or a negative on these new developments still exist.

One of the large factors obstructing the earthquake precursor research by the conventional ground based 
observation is the long time needed to accumulate useful data because the occurrence of large earthquakes is 
limited in space and time.

  On the other hand, however, the satellite observation can afford global coverage so that relevant data may be 
obtained in a short time. In fact, globally, magnitude 7 to 8 class large earthquakes occur about 10 to 20 times 
every year on the average. It is the main reason why satellite observation is executed and proposed by many 
countries.

  One of the purposes of the workshop is to inform the existence of the effects of earthquakes on the ionosphere 
to ionospheric scientists. As you may be well aware that only a few ionospheric scientists are pursuing this issue in 
the world.

  Second purpose of the workshop is to discuss the satellite missions, which scientists from several countries are 
trying to propose. To accelerate the action toward the satellite mission, we should collaborate.

Toward the satellite mission, we would like to discuss the instruments to be onboard, orbit and many other related 
matters.
