摘要
系统地总结分析了巴颜喀拉地块北、东、南边界带的构造特征、各个边界带上的强震活动、部分强震的震源机制解和区域地震活动,从而探讨了2010年玉树7.1级地震发生前巴颜喀拉地块地震活动特征。从2008年玉树地区地震活动变化、巴颜喀拉块体北边界和南边界强震呼应及块体动力学过程进行了地震趋势预测的思考。
In this paper, the Bayankala block structural features of North, East and South border zone, the strong earthquake activity on the border, some strong earthquakes focal mechanism and regional seismic activi- ty are summarized and analyzed. The characteristics of seismic activity of Bayankala block before Yushu Ms7. 1 earthquake in 2010 are discussed. The earthquake trend prediction is studied according to the seismic activity in Yushu in 2008, the North and South boundaries of Bayankala blocks echoed strong earthquakes, and the process of block dynamics.
