【摘要】 通过对元江水氡观测资料的分析,发现其在滇南及滇西南地震之前有很好的对应关系,是滇南及滇西南地区发生中强地震的一个敏感测项.其映震特征为:日测值成组的、大幅度的高值突跳,且5日均值出现长时间的超过1倍均方差线,同时伴随有井口翻花冒泡、流量增大等宏观现象.当元江井出现宏观异常现象后,一般均有至少2个5级以上地震发生或1个6级以上地震发生.更多还原

【Abstract】 By Analyzing the observation data of Yuanjiang water radon,we found it has a very good corresponding relationship before the earthquake of south Yunnan and southwest Yunnan,and it is a sensitive material before the earthquake in south Yunnan and southwest Yunnan.It`s earthquake reflecting characteristics is:when the day average appears anomaly sudden jump in groups,and five day average more than 1 times average variance line for a long time,and accompanied macroscopic phenomena at the wellhead such as inverted flower bubbling and flow rate increases.When the wellhead appears macroscopic phenomena,there will be at least two ML≥5 or one ML≥6 earthquake generally.更多还原
