| 摘 要： | 2016年青海省发生门源6.4级和杂多6.2级地震,针对2次6级以上地震发生前热红外数据变化特征进行分析,研究发现:门源6.4级和杂多6.2级地震前热红外辐射增强变化应为地震异常;2次地震映震结果对比表明,频段1、4和5为优势映震频段,异常幅度为年均值4.5倍左右可作为地震异常判断依据。

| Abstract: | In 2016, there occurred Menyuan MS 6.4 earthquake and Zaduo MS 6.2 earthquake in Qinghai Province. In this paper, it is analyzed the characteristics of thermal infrared data before these two earthquakes and found the increase of thermal infrared radiation before the Menyuan MS 6.4 and Zaduo MS 6.2 earthquakes are earthquake anomalous. The comparison between the two earthquakes shows that the 1, 4 and 5 bands are the dominant reflection frequency bands and the abnormal amplitude of about 4.5 times the annual average value, so that could be considered as the basis of earthquake anomalies. |
