There are many seismographic stations in the world, that receive seismic waves generated by earthquakes. We proposed the establishment of a new type of seismic station, which continuously transmits seismic waves with artificial source. By use of seismic wave generated by the transmitted stations we can obtain the image of deep Earth. The key problem of the transmitted station is to find the suitable artificial seismic source: powerful, green and clear sources. With the development of air-gun technique and information theory, it is possible now to obtain the image of a 100 000 km2 in spatial coverage and 40 km in depth (deep to Moho) by use of the transmitted seismic stations.
Key words： Image of deep Earth; 100 000 km2; Air-gun in land.; Transmitted station
