丰满地震台水氡对M≥5.0级东北深震的映震分析
|
摘要
在对丰满地震台水氡井的基本情况和水氡的动态影响因素分析的基础上,列举并分析了该测点自1987年1月1日到2011年12月31日期间M≥5.0级东北深震前后水氡资料的异常形态,得出水氡具有一定的深震效应。结合深震震源机制和水氡井所处特殊区域地质构造,对深震前后异常形态问题进行了初步解释,为今后利用水氡异常形态判别深震发生提供依据。
Based on analysis of geological structure and dynamic impact factors of water radon well in Fengman Seismic Station,the paper illustrates and analyzes water radon anomaly morphology before and after M≥5.0 deep earthquakes in Northeast from January 1st,1987 to December 31st,2011.Combination of earthquake mechanism and well's geological structure,the author gives some initial explanations and proposes water radon anomaly may be used to tell the occurrence of deep earthquakes to some extent.
