【摘要】 在《西太平洋过渡带及其邻区内强震的活动性及其震源机制特征》一文里,我们分析讨论了西太平洋过渡带及其邻区内强震的地震活动性和震源机制特点,得出结论:1.太平洋板块和欧亚板块之间的相互挤压运动是所讨论地区内构造地震(包括板间和板内)共同的动力来源.2.板块边界上的动力被传递到板块内部,造成中国东部的板内地震,板内地震的活动性和板内已有构造的几何性质和力学性质有关.3.板块不是完全刚性的,应力在一定的条件下被传递.构造之间以及同一构造的不同部分之间的应力的积累和释放是相互耦合的.本文继承该文章的思想,进一步深入分析所讨论地区的地震活动性及其与地震带深大断裂运动之间的关系.为预测板内地震的途径提供了某种思路.更多还原

【Abstract】 In our preceding paper,《Seismicity and characteristics of Focal Mechanism of Strong Earthquakes In the Western Pacific Transition Zone and Its Neighbourhood》,We have analyzed and discussed the seismicity and characteristics of focal mechanism of strong earthquakes in Pacific transition zone and its adjacent areas.We have reached the conclusions: (1) The Pacific plate,Philippines and Eurasia plate are pressed by each other.It is the common motive force source of tectonic earthquakes(both inter and intra plate earthquakes) of the discussed area. (2) The motive force can be transmitted from the boundary to the inner part of the plate, it causes the earthquakes of North and East China.The intraplate seismicity is closely related with the geometry and dynamic properties of deep and big fault belts which already existed. (3) The plate is neither completely rigid,nor homogeneous.The motive force is transmitted under certain condition.So that the accumulation and release of stress on different parts of same fault belt or different fault belts are coupled with each other. In this paper,following the views of the preceeding paper we further analyze and discuss the seismicity and its relation with the motion of deep and big fault belts in North China.更多还原
