| 摘 要： | 分析了新疆3次6级强震前的短期前兆异常动态演化图像特征。这3次地震前兆异常的共性是地震前半年都出现了不同程度的短期前兆异常变化,且在震前2个月,短期异常均超过8项。但是3次6级强震发生前前半年的短期前兆异常变化不一致,有向震中迁移的,有包围震中的,还有前兆异常逐渐减少的。这些前兆异常现象同通常认为的越临近地震前兆异常数目越多是不一致的。

| Abstract: | Using the characteristics of dynamic evolution image about precursory abnormities of short-term before 3 strong earthquakes with MS6 in Xinjiang, we obtain some results as following.Before 3 strong earthquakes with MS6 occurred,the same characters are that there are some different changes of precursory abnormities of short-term about half a year before earthquakes.And in two month before earthquakes,the precursory abnormities of short-term all exceeded 8 items.The complexity is that all precursory abnormities of short-term is inconsistent in half a year before earthquakes.Some of them are to migrate to epicenter.Some of them are to surround the epicenter,and others of them are to reduce gradually.It is inconsistent with we thought as usually.That is more approaches the earthquake is,the more number the precursory abnormities are. |
