以往人们都将宝鸡、陇县(以下统称宝鸡)地区与西吉、海原、固原(以下统称西海固)地区统归一体来论述其地震活动性,萁原因就是二者同处于陇西旋卷构造体系。因而,西海固地区一但有震情活动;就把它作为依据来推测宝鸡地区也具有发震的危险性。我们认为,两区地震活动的差异还是相当大的,甚至是完全不同的。以下列举几点来说明这个问题。
In the past, all of them discussed the seismicity of Baoji, Longxian (hereinafter collectively referred to as Baoji) and Xiji, Haiyuan and Guyuan (hereinafter referred to as Xihaigu). The reason is that both of them are located in the Longxi rotational volcanic tectonic system . Therefore, once there is an earthquake event in Xihaigu area, it will be used as a basis to speculate that the earthquake in Baoji area is also dangerous. In our opinion, the differences in seismicity between the two districts are still quite large or even completely different. Here are some points to illustrate this issue.
