摘要
专题讨论了1927年古浪8级大震的基本特征,包括地震的基本参数、震中位置的确定、震源深度及震级、断层面解、地震活动序列等特征,并在此基础上,依据区域断层面倾角及震源随深度的变化特征,讨论了发震断层在地壳深部的几何形态,为进一步认识1927年古浪8级大震的形成机制奠定了基础。
The authors have discussed the fundamental characteristics of Gulang Ms 8 earthquake in 1927, included the fundamental paramters, the source position, the depth and the magnitude,solution of the fault plane and the seismic active sequence. According to these and the features of dip angle of fault plane and the source changed with the depth,they have also discussed the geometry of the occurrence fault in the deep crust,and laid foundation for studying deeply the mechanisms of the Gulang earthquake in 1927.
