Abstract: With the breakthrough of a series of techniques such as measurement of fault morphology, dating of cosmogenic nuclides, measurement of geochemical elements and the optically stimulated luminescence, the dominant characteristics of bedrock faults in paleo-earthquake research have been constantly explored and it has increasingly become international hotspots and frontiers of paleo-earthquake research. Scholars at home and abroad have carried out a large number of paleo-earthquake studies on bedrock faults from different professional perspectives, and have achieved a series of fruitful results. This paper systematically introduces the current situation, summarizes main research methods of paleo-earthquake study on bedrock fault surfaces, points out some problems existing in selecting a suitable study site. Finally, some aspects that need to be strengthened in the future are proposed, and prospects of paleo-earthquake research on bedrock faults are given.
