Abstract:The research findings about regional stress state of Tanlu fault belt were summarized,including the maximum stress directions and magnitudes,the stability of regional faults and dynamic mechanism.The maximum stress direction is NEE in the north segment,and the southern segment,and nearly EW in the middle segment.The fault zone is mainly controlled by the Pacific Ocean plate and East Asia plate.The review shows the whole stress state of Tanlu fault zone,which provides basis for the future research on taking precautions against earthquake.
