The review of the research on buried active faults all over the world has indicated that the exploration and research of buried active faults have experienced 3 main development stages: the development of exploration technique (the early stage), the use of single exploration technique (the middle stage), and the use of multiple exploration techniques (the modern stage). In the 1990s, comprehensive exploration of buried active faults through shallow seismic prospecting and drill logs has been carried out in China, Japan and the United States, for the purpose of major engineering construction and seismic hazard reduction. Good progress has been made in locating buried active faults and timing of fault activity. According to the present situation of the research of buried active faults and its heavy responsibilities, great attention should be paid to the following problems: (1) how to enhance the coordination of various exploration techniques, especially the coordination of a series of drill logs with the corresponding age dating and shallow seismic prospecting; (2) attention should be paid to the improvement of the locating precision of buried faults and the determination of displacement amount; (3) how to focus our research on the meticulous quantitative determination of the age of fault activi~ty and the displacement amount. It is suggested, therefore, that the precise location of buried active faults and the quantitative research of their Quaternary activity, the relationship between the Meso Cenozoic active faults with the late Quaternary active faults, the 3 dimensional correlation between the seismogenic fault and the shallow level fault, as well as the the establishment and application of the 3 dimensional geologic structural model of buried active fault in plain area are the main key problems and difficulties in the research and exploration of buried active faults at present. According to the present development of the research of buried active faults and the demands of national economic constructi
