濮阳2次ML4.0级地震前兆异常研究

STUDY ON THE PRECURSORY ANOMALY BEFORE TWO ML 4.0 EARTHQUAKES OCCURRED IN PUYANG

    摘要
  • 摘要: 介绍了濮阳2次ML4.0级地震的基本参数。2次地震前出现了电磁波、水位、逸出气氦等异常。对前兆资料的异常特征进行了分析研究。异常出现的起始时间、持续时间、异常幅度等不同手段、不同台站在地震前的表现各不相同,表现出异常的复杂多样性。

     

    Abstract: The parameters of two ML4.0 earthquakes occurred in Puyan are introduced. Some anomalies of electromagnetic wave, groundwater level and helium gas had appeared before the two events. The characteristic of these anomalies is analyzed. As the beginning time, duration and magnitude of the anomalies are different in stations, it shows the complicated feature of the anomalies.
