| 摘 要： | 采用差分、滤波、拟合、去周期等方法,分析了临潼地震台流体与汾渭地震带上的地震及个别远场大震的关系,着重以洪洞地震为例,详细分析了地震前后临潼台流体的异常变化特征。结果表明:临潼台水氡、水温在震前以中长期、短期前兆异常为主,水溶气主要表现为短临前兆异常。

| Abstract: | The characteristics of subsurface fluid anomalies in Lintong Seismostation before Hongdong earthquake is analyzed with difference,filtering,fitting,period eliminating method.The results show that the water radon and water temperature anomalies in Lintong Seismostation are mainly moderately long term and short term anomalies,and dissolved vapor anomalies are mainly imminent anomalies. |
