利用热红外遥感数据地震处理软件，对中国静止气象卫星FY2C／2E亮温观测数据进行处理，得到2008年3月21日和2014年2月14日于田2次7．3级地震的热红外异常特征。结果表明，热红外异常特征周期均为64天，震中发生于热异常区边缘和热异常条带交汇部位；2008年地震短临异常显著，2014年地震中短期异常明显；西昆仑和阿尔金断裂带的热异常起伏程度相似，热红外异常可能与断裂活动密切相关。在监测能力弱的地区，开展热红外资料在地震预测应用研究工作，可以弥补地震前兆监测能力弱的问题。%Thermal infrared remote sensing data processing software of FIXSATELLITE is used to process Chinese geostationary meteorological satellite FY 2C/2E brightness temperature data , and thermal infrared anomalies of two Yutian 7.3 earthquakes which occurred on March 21st, 2008 and February 14st, 2014, respectively, are obtained.The results showed that the thermal infrared anom-aly period was 64 days, the epicenter occurred in the thermal anomaly zone edges and intersections of thermal anomalies strip .The short impending anomaly of 2008 earthquake was significant , and short-term anomaly occurred before 2014 earthquake .Thermal anomalies of west Kunlun and Altun fault fluctuated similarly , which may be associated with active faults .In areas of weak monitoring capacity , thermal infrared data can be used in earthquake prediction research , which can compen-sate for weak earthquake precursor monitoring capacity problem .
