| 摘 要： | 基于Coulomb静应力变化的概念，研究了青藏高原北缘的海原（1920年2月,M=8.5）、古浪（1927年5月,M=8.0）和昌马（1932年12月,M=7.6）3次大地震之间的相互关系。结果表明，海原大地震发生可能诱发古浪大地震提前16～44a发生；而昌马地震发生可能不受海原和古浪地震诱发静应力变化的影响。

DYNAMIC ANALYSIS ON INTERACTION BETWEEN THEHAIYUAN-GULANG-CHANGMA GREAT EARTHQUAKE IN THE NORTH BOUNDARY OF THE TIBETAN PLATEAU |
| |
| Abstract: | This paper has studied the interaction between theHaiyuan-Gulang-Changma gre at earthquake on the north boundary of the Tibetan plateau based on the concep tion of Coulomb static stress change. The results show that the Gulang earthqua ke occurred in advance of 16～44 years from triggering by Haiyuan event, and the occurrence of Changma earthquake was not affected by Coulomb static stress change resulting from Haiyuan and Gulang earthquake occurrence. |
