摘要

应用中国静止气象卫星FY-2E红外遥感资料对2013年甘肃岷县漳县6.6级地震前的热红外异常信息进行研究,结果表明:由地震黑体辐射热异常时空演化图分析知,中强地震前,往往会有较大范围的热异常演变,热异常大面积沿断层分布,震中位置往往位于边界或热异常变化最大处。对比实时的长波辐射涡度场变化,能更好的对应未来地震的发震区域,涡度异常经常分布在震中边界。
The thermal infrared anomaly information is studied by the application of the static meteorological satellites FY- 2E infrared remote sensing data before Minxian-Zhangxian earthquake with Ms 6. 6 in 2013 in Gansu province,the results show that the wide range of abnormal thermal evolution is appeared which distributed along the fault before the strong earthquakes by the analysis on the seismic blackbody radiation diagram and space-time evolution,the epicenter is located in the border or largest changes of thermal anomaly. The future earthquake can be forecasted by compared the real-time longwave radiation vorticity field change which usually distributed near the border of the epicenter.
