Remote Sensing Analysis on Neotectonic stress field in the middle part of Shule River Fault

,Based on the information of remote sensing images from landsat MSS ,TM and space shuttle SIR A, the interpretation on active faults in the middle part of Shule River is carried out in this paper.It is confirmed that the direction of main compressive stress of neotectonic stress field is northeast and southwest in this area by analyzing the characteristics of active fault and basin mechanics. According to the genesis of fault related earthquake and geomechanics theory, this paper studies the stress state of active faults and mechanics condition of quake formation.The difference of stress state among the east, middle , west part of Shule River fault shows that there is no mechanics condition for earthquake, and very little probability for big earthquake.Therefore, the pre selected high level nuclear waste disposal site in North Mountain, Gansu is safe from earthquake.
