摘要: 以静止卫星中波红外亮温为数据源， 应用功率谱相对变化法对2008年新疆于田MS7.3和2010年青海玉树MS7.1地震进行了分析研究. 结果表明， 两次地震前均出现了不同程度的功率谱信息增强现象， 特征周期分别为64和13天； 两次地震前特征功率谱幅值达到近几年来的相对最大值或极值， 且功率谱幅值均在6倍以上； 两次地震前、 后功率谱幅值大于2倍的持续时间均为近80天， 异常极值时功率谱幅值大于6倍的范围面积分别达12万和4万平方千米. 上述结果与长波辐射通量和热红外亮温资料的研究结果基本一致， 可为将来实现多波段同时监测热辐射变化进行地震预测提供参考.Abstract: This paper use middle infrared brightness data from geostationary satellite to research the 2008 Yutian MS7.3 and the 2010 Yushu MS7.1 earthquakes by estimating relative variance rate of power spectrum. The results show that the power spectrum amplitude of middle infrared brightness increased at different degrees before the two earthquakes. The characteristic periods were about 64 days and 13 days respectively. Before the two earthquakes, characteristic power spectrum amplitudes reached relatively the maximum or extreme in recent years, which were over six times of their average. The duration of power spectrum amplitude over twice of average were 80 days. The extreme areas of power spectrum amplitude over six times of average reached about 120000 and 40000 square kilometers respectively. These results are basically consistent with the previous results from outgoing long-wave radiation and thermal infrared brightness temperature data, which can be used as reference for realizing multi-wave band monitoring of heat radiation so as to predict earthquake in the future.
