摘要
本文通过德都震区、宏观异常区、两个火山口等四条断层气(土壤氡含量)剖面测量结果与德都地震的宏观异常资料的对比分析,对德都地震的形成原因、发生条件进行了讨论。提出德都地震是一次区域性构造活动事件,并与岩浆活动起伏有关。
Based on the measurement of fault gas (radon contents in soil)released from four profiles along the Dedu seismic area,macroscopic anomaly zone and two volcanic craters,and comparing the results with the macroscopic anomalies occurring in the Dedu seismic area,the origins and generation conditions of the Dedu earthquake are discussed in this paper. It is showed that the Dedu earthquake is a regional tectonic event and related to the fluctuations of magma activity.
