摘要
在宁夏灵武ML4.6级地震、甘肃礼县ML5.2级地震、甘肃岷县ML5.3级地震和甘肃华亭ML4.2级地震前后,周至井的气氡观数据均出现了大幅度的上升异常,说明周至井的气氡异常和邻近地区的地震有着较好的对应关系,本文对出现这种对应关系的机理进行了讨论。
Before and after Lingwu ML 4. 6 earthquak, Lixian ML 5.2 earthquake, Minxian ML 5. 3 earthquake and Huating ML 4.2 earthquake, gas radon in Zhouzhi well raised abnormally. It is suggested there is a good corresponding relationship between gas radon in Zhouzhi well and earthquake in neighboring regions. The mechanism of the corresponding relationship is discussed in the paper.
