These studies provide important clues in understanding the physical process of hazardous events such as earthquakes and volcanic eruptions. In this review we introduce the practices and advances in exploring and monitoring the subsurface structure with artificial seismic sources. This review is orgainzed as follows. Firstly,we describe the studies on the characteristics of different types of seismic source( especially the airgun source). Then the advances on data processing and mechanical understanding are depicted. At the end of this review,we reveal the prospects of future study of exploration and monitoring of the subsurface structure and its temporal variations using artificial sources.展开更多
