摘　　要：早在公元132年东汉张衡发明地动仪时．中国人就已经认识到地震是远方传来的地面振动。从波动观点对地震的认识是本质性的。近代地震学作为一门独立的学科，很大程度上是由研究地震波传播的知识体系所支撑的。Earthquakes can be regarded as the lamp that sheds lights on the structure and internal processes of the Earth.To utilize the earthquake,we are faced with some problems as poorly determined location and origin time as well as the clustered distribution of seismic zones.Using active sources we can detect the structure and its evolution for a specified region,this process is quite similar with the brightness mode used in medi- cal diagnosis,so we call it GEO-BM.The paper discusses its significance and possibility.And based on data analysis of recent active source-seismic experiments,we regard the Airgun source as an ideal source for the performance of GEO-BM.
