【Abstract】 Developments in the research in physics of earthquake source since the 1990's in China are reviewed in perspective of observation, theoretical modeling, and laboratory experiment. These developments include: estimation of source parameters of continental earthquakes; inversion of the ‘modern’ earthquake parameters, such as moment tensor and slip function, using digital broadband seismic data; application and development of fracture mechanics; application of non-linear dynamics in the study of earthquake source; laboratory experiments characterized by improved resolution; and experimental studies of the mechanism of the possible earthquake precursors. It is pointed out that the development of high-technology and modern physics has a significant influence on the research of physics of earthquake source in China, leading to a better understanding of the complexity of continental earthquakes. The study in physics of earthquake source in China in the turn of the centuries is prospected in the view of the development of modem seismology. It may be expected that such studies will play an active role in the social endeavor of the reduction of seismic hazards.
