Abstract: The Qixian-Xinxiang-Jiaozuo area is located at the southern section of the piedmont.fault belt of the Taihang mountain,which is one of main earthquake risk areas in China.In addition to geological structures and lithological characteristics,the condition of stress is also considered as one of essential factors for the occurrence of a strong earthquake.Recent tectonic stress state in this area has been studied by analysing recent activities of faults,ground water fluctuations and local mechanisms.From these studies the author suggests that recent regional tectonic stress fields are characterized by ENE-WSW horizontal principal compressional stress and NNW-SSE horizontal principal tensional stress.Recent tectonic stress state and its relation to seismicity have been studied by means of the finite element method.The calculations show that in the Xinxiang-Xiuwu complicated rhombic fault block,under the action of recent regional stress fields,the east and west acute angle region where two earthquakes of M=5.5 and M=6 have occurred is in a process of being highly stressed and may be a candidate of a strong earthquake.
