Researches on the yearly characteristic of IR brightness temperature and the different hypsography on the active faults

GUO Wei-ying1,MA Jin2,SHAN Xin-jian2(1.Seismological Bureau of Xinjiang Uyger Autonomous Region,Urumqi 830011,China;2.State Key Laboratory of Earthquake Dynamics,Institute of Geology,China Seismological Bureau,Beijing 100029,China)  
By using the CH5 infrared(IR) night-time thermal images of the NOAA satellite and the digital elevation models(DEM),this thesis studies the dynamic change of the IR brightness temperature on the active faults in the years without major earthquake.Taking several examples of the eastern Kunlun fault,the Altyn fault and the Qiliansha-Haiyuan fault which are seated on the northern of the Qinghai-Tibetan plateau,the results show that topography has a dominate control on the yearly change of IR brightness temperature on the both sides of the faults,of which the IR brightness temperature are well negatively correlated with elevation variations,and the negative correlation comply with the vertical lapse rate of the temperature basically.Besides of this,rock differences,distribution of water and frequent human activity have also effect on the both sides of faults.It is of great importance to study the IR radiation brightness temperature seasonal changes on fault,it would provide some reference and help for the effects of earthquake prediction by means of satellite remote sensing IR technique.
