| 摘 要： | 根据MODIS卫星热红外数据，利用透热指数法和亮温增温异常点比值法，分析福建地区地震震前的热红外时空异常变化，发现透热指数与福建地区中等地震有较好的对应关系，而地表的亮温增温异常区与未来发生的地震震中较为接近。

| Abstract: | Based on the MODIS satellite thermal infrared data and using the methods of heat penetrability index and ratio of pixels with abnormal brightness temperature increasing, a good correlation between moderate earthquakes in Fujian and heat penetrability index anomalies has been found. In addition, the abnormal areas are close to epicenters of subsequent earthquakes. |
