| 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.

| Abstract: | 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 distribu- ted 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. |
