摘要
本文通过对青海Ms≥6.4级地震发震地点的分析,认为青海高原及邻区的6.4级以上地震具有明显的等间距特征。地震位于北东向和北西向网络的交汇点附近,网络节点间距为230公里左右,网络呈菱形。并初步讨论了其成因的地球物理机制。
In this paper, the author think that the earthquakes with magnitude over 6.4 have obvious equally spaced through analysing the locales of earthquakes Ms≥6.4 in Qinghai province and its adjacent areas. Meanwhile, the epicentre is near by point of intersection in NE and NW direction network, the network is rhombus, and space is about 230km. Finally, the genetic geophysical mechanism is also studied preliminarily.
