唐山7.8级地震前水氡异常演化特征

THE EVOLUTION FEATURE OF THE WATER RADON ANOMALY BEFORE THE TANGSHAN M 7.8 EARTHQUAKE

  • 摘要: 根据华北地区分布的33 个水化观测点的水氡观测资料,以半年为尺度对唐山7.8 级地震前水氡的异常演化过程进行了研究,认为:唐山7.8 级地震前水氡异常存在由外围向震中区演化的异常特征,且在唐山地震发生的短临阶段,水氡异常在唐山地区形成集中,异常强度最大。

     

    Abstract: On the basis of water radon data of 33 wells distributed in North China and taking per half of a year as a scale, the evolution processes of the water radon before the Tangshan M7.8 earthquake are studied. The results are: the water radon anomalies were progressively developed from the outer ring to the epicentral area before the Tang shan M7.8, the earthquake occurred in its short-imminent stage, at this stage, water radon anomalies were accumulated at Tangshan area and the anomalous intensity was the bigest.
